Kerala Plus One Physics Notes Chapter 12 Thermodynamics

Summary
Thermo dynamics is the branch of Physics that deals with concept of heat and temperature, their inter-conversions and other forms of energy. In thermo dynamics state of system is specified by macroscopic variables such as pressure, temperature, volume, mass, composition… etc.

Thermo Equilibrium
Thermo dynamic equilibrium:
A system is said to be in thermodynamic equilibrium if the macroscopic variables used to describe the system does not change with time.
Eg: Agas enclosed in a rigid container (characterized by P, V, T, m, and composition) The equilibrium of a thermodynamic system depends on surroundings and nature of wall that separates the system from surroundings. The wall can be

  • Adiabatic wall – It does not allow flow of heat (energy).
  • Diathermic wall – It allows the flow of heat (so that it can comes to thermal equilibrium).

Plus One Physics Notes Chapter 12 Thermodynamics

Zeroth Law Of Thermodynamics
Zeroth law of thermodynamics gives concept of temperature. R.H Fowler formulated this law in 1931. According to Zeroth law of thermodynamics, the systems in thermal equilibrium with a third system separately are in thermal equilibrium with each other.

Let A & B are in thermal equilibrium with each other. If they are separately in thermal equilibrium with C, then the three systems are in thermal equilibrium
(TA = TB = TC).

Heat, Internal Energy And Work
Internal Energy (U):
internal energy of a gas is the sum of potential energy and kinetic energy (translational kinetic energy, rotational kinetic energy and vibrational energy) Internal energy is a thermodynamic variable and hence it depends on state of the thermodynamic system.

Heat and Work:
The internal energy of a system can be changed either by heat or by work. Heat is energy transfer between a system and surroundings due to temperature difference. Work is mode of energy transfer brought about by means like moving piston (it is not due to temperature difference)

First Law Of Thermodynamics
According to first law of thermodynamics, heat supplied to a system is used to increase its internal energy and to do work.
If ∆Q is heat supplied to the system, ∆W is work done by the system and Au is change in internal energy, then ∆Q = ∆U + AW
Note:

  • If the entire heat supplied to the system is used to do work, then ∆Q = ∆W
  • The work done against constant pressure, ∆W = P∆V, ∆Q = ∆U + P∆V.

Specific Heat Capacity
Molar specific heat capacity of solid:
Consider a solid consisting of N atoms. Each atom have an average energy 3KBT, where KB is Botlzman constant. Total energy for one,mole
U = 3KBT × NA
NA is avagadro number.
At constant pressure, ∆Q = ∆U + P∆V
For solid ∆V is negligible ∆Q = ∆U
Molar specific heat capacity
Plus One Physics Notes Chapter 12 Thermodynamics 1

Plus One Physics Notes Chapter 12 Thermodynamics
Thus molar specific heat capacity of solids is found to be 3R. But at low temperature molar specific heat capacity is not a constant.
Specific heat capacity of water:
The specific heat capacity of water is 4186 J Kg-‘K1. But the specific heat capacity of water changes with temperature as shown.
Plus One Physics Notes Chapter 12 Thermodynamics 2
Mayor’s Relation; Cp – Cv = R
If molar specific heat capacity of constant pressure is Cp and that at constant volume is Cv then Cp – Cv = R, for an ideal gas.
Proof:
According to 1st law of thermodynamics
∆Q = ∆U + P∆V
If ∆Q heat is absorbed at constant volume (∆V = 0)

Plus One Physics Notes Chapter 12 Thermodynamics 4
Substituting in equation (2)
Plus One Physics Notes Chapter 12 Thermodynamics 5
Equation (4) – Equation (1), we get Cp – Cv = R.

Thermodynamic State Variable And Equation Of State
Extensive and Intensive variables:
Thermodynamic variables can be extensive or intensive. Extensive variables depend on size of the system.
Eg: mass, internal energy, volume.
Intensive variables are independent of size of system.
Eg: Pressure, temperature, density.
Equation of state:
The relation between state variables of a system is called equation of state. For an ideal gas equation of state is PV = µRT

Thermodynamic process
1. Quasi-static process:
The thermodynamic process in which thermo dynamic variables (P, V, T… etc) changes so slowly that the system remains in thermal and mechanical equilibrium is called quasi static (nearly static) process. In quasi-static process change in temperature or pressure will be infinitesimally small. The different types of quasi static process are listed in the above table.

2. Work done in isothermal process:
For an isothermal process, the equation of state is
PV = constant = µRT
P = \(\frac{\mu \mathrm{RT}}{\mathrm{V}}\)
Let a system undergoes an isothermal process at temperature T, from the state (P1, V1) to (P2, V2). Let ‘DV’ be a small charge in volume due to pressure P.
Then work done (for ∆V)
∆W = P∆V

3. Work done by adiabatic process:
Let an ideal gas undergoes adiabatic charge from (P1, V1) to (P2, V2). The equation for adiabatic charge is PVγ = constant = k
Plus One Physics Notes Chapter 12 Thermodynamics 8
from equation (a) P1V1γ = P2V2γ = k

Plus One Physics Notes Chapter 12 Thermodynamics
Substituting ideal gas equation.
Plus One Physics Notes Chapter 12 Thermodynamics 10
Note:

  1. The graph connecting P and V of isothermal process is called isotherm.
  2. In adiabatic process
    • T1 < T2, then work is done on gas (w < 0)
    • T1 > T2, then work is done by gas (w > 0)
  3. For Isothermal process
    • V1 < V2, w > 0 work is done by gas
    • V1 > V2, w < 0 work is done on gas.
  4. In isochoric process no work is done on or by gas because volume is constant.

Cyclic process:
In cyclic process, the system returns to its initial state such that change in internal energy is zero. The P – V diagram for cyclic process will be closed loop and area of this loop gives work done or heat absorbed by system.
Plus One Physics Notes Chapter 12 Thermodynamics 11

Heat Engines
Heat engines converts heat energy into mechanical energy. Heat engine is a device by which a system is made to undergo a cyclic process that results in conversion of heat to work.
Heat engines consists of:

  1. Working substance (the system which undergoes cyclic process) eg: mixture of fuel vapor and air in diesel engine, steam in steam engine.
  2. An external reservoir at a high temperature (T1) – it is the source of heat.
  3. An external reservoir at low temperature (T2) or sink

Plus One Physics Notes Chapter 12 Thermodynamics 12

Plus One Physics Notes Chapter 12 Thermodynamics
Working:
The working substances absorbs an energy Q1 from source reservoir at a temperature T1. It undergoes cyclic process and releases heat Q2 to cold reservoir. The change in heat (Q1 – Q2) is converted in to work (mechanical energy).
Efficiency of heat engine (η):
The efficiency of heat engine is the ratio of work done to input heat.
Plus One Physics Notes Chapter 12 Thermodynamics 13
Note:

  • Q2 = 0, η = 1. When entire heat input is converted into work heat engine is 100% efficient. But practically 100% efficiency cannot be achieved. It is limited by second law of thermodynamics.
  • Heat engine can be external combustion engine or internal combustion engine.

In external combustion engine, the fuel (system) is heated by external furnace.
Eg.: Steam engine.
In internal combustion engine, fuel is heated internally by exothermic chemical reactions.
Eg: Diesel engine, Patrol engine.

Plus One Physics Notes Chapter 12 Thermodynamics

Refrigerators And Heat Pumps
Refrigerator is reverse of heat engine, the device used to cool a portion of space (inside a chamber) is refrigerator. The device used to pump heat into a portion of space (to warm-up room) is called heat pump.

In both devices, the working substance absorbs heat Q2 from cold reservoir at temperature T2. Some external work (by compression of gas by electric means) is done on it and heat Q1 is supplied to hot reservoir at T1.
Plus One Physics Notes Chapter 12 Thermodynamics 14
The working cycle of refrigerator:
In refrigerator the working substance is a gas (freon)

Step1: The gaseous working substance is converted into vapor- liquid mixture at lower temperature (T2)
Step 2: The cold fluid absorbs heat from region to be cooled (cold reservoir) and convert it into vapor.
Step 3: The vapor is heated by external work.
Step 4: The vapor release heat to surroundings and then comes to initial temperature T2.

The coefficient of performance (α):
The coefficient of performance of refrigerator is defined as
α = \(\frac{Q_{2}}{W}\)
where Q2 is heat extracted from cold reservoir and W is work done on system.
Note:

  • The working substance in refrigerator is termed as refrigerant.
  • For heat engine η can not exceed 1. But α can be greater than one.

Second law of Thermo dynamics
Kelvin – Plank statement:
No process is possible whose sole result is the absorption of heat from a reservoir and complete conversion of heat into work.
Clausius statement:
No process is possible whose sole result is the transfer of heat from a colder object to hotter object.

Plus One Physics Notes Chapter 12 Thermodynamics

Reversible And Irreversible Processes
A themodynamic process is said to be reversible if the process can bring both system and surrounding back to the original state without any change.

A reversible thermodynamic process is ideal case. Most thermodynamic processes are irreversible because the process involves dissipative effects like friction, viscous force etc. and during such process, system passes through non-equilibrium states.
Note: Condition for a thermodynamic process to be reversible is

  1. Quasi static
  2. non-dissipative

Question 1.
What is the importance of reversibility in thermo dynamics?
Answer:
The main concern of thermodynamics is efficiency with which heat can be converted into work. According to second law of thermodynamics, the efficiency can not be 100%. The heat engine can have highest efficiency only if the cyclic process is reversible.

Carnot’S Engine
Carnot’s theorem:
Sadi carnot proposed Carnot’s theorem. According to Carnot’s theorem

  1. No engine operating between two temperature can have efficiency more than that of Carnot’s engine,
  2. The efficiency of Carnot’s engine is independent of nature of working substance.

Carnot’s engine:
A reversible heat engine operating between two temperatures is called Carnot’s engine.
Carnot’s cycle:
The Carnot cycle consists of two isothermal processes and two adiabatic processes.

खाना कोई भी जीवों की आधारभूत आवश्यकता है। खाना नहीं है तो कोई भी जीव अपनी जिंदगी को आगे नहीं ले जा सकती है। अकाल की वजह से केवल मनुष्य ही नहीं अन्य जीव भी मुसीबत में पड़ जाते हैं। अकाल के कई कारण होते हैं। आज की पीढ़ी खेती के महत्व को भूल जाते हैं। नई पीढ़ी खेती से मुंह मोड़ कर आ रही है। सब लोग सफ़ेदपोश नौकरी के पीछे पड़े रहे हैं। हमारे राज्य में खेत और खेती दिन व दिन कम होता जा रहा है। नई पीढ़ी का दायित्व है खेती के प्रति रुचि पैदा होना। सब लोग खेती के महत्व को समझें और खेती की उन्नति के लिए कार्य करना चाहिए।

How many roads must a man walk down
Before you call him a man?
How many seas must a white dove sail
Before she sleeps in the sand?
Yes, and how many times must the cannon balls fly
Before they’re forever banned?
The answer, my friend, is blowin’ in the wind
The answer is blowin’in the wind.

Yes, and how many years can a mountain exist
Before it is washed to the sea?
Yes, and how many years can some people exist
Before they’re allowed to be free?
Yes, and how many times can a man turn his head
And pretend that he just doesn’t see?
The answer, my friend, is blowin’ in the wind
The answer is blowin’ in the wind.
Answer:
Bob Dylan’s “Blowin’ in the Wind” asks a series of rhetorical questions, some gentle, some very penetrating. Rhetorical questions are questions for which the answer is already known. They are actually meant to make us think.

In the first stanza itself the poet asks a number of questions. How many roads should a man walk before he can be called a man? How many seas should a white dove sail before she can rest? How many times should the cannon balls fly before they are banned? The answers are there but nobody wants to find them.

The 2M stanza has also three questions. How long the mountains can last, how long can people live without being free and how many times can a man turn his head and pretend that he just doesn’t see? The answers are blowing in the wind.

The third stanza also has 3 big questions. How many times’ must a man look up before he can see the sky? How many years must one have before he can hear people cry? How many deaths will it take for him to know that too many people have died?

The poem is aimed at our emotions in order to sensitize our consciences. The poet wants to say that enough evil has already occurred in the world and so let us stop it. The language is simple, direct and powerful. The poem reminds us the teaching of Jesus who said, “Let people with eyes see and people with ears hear.” The poem is actually a song and very melodious. There is fine imagery. There is repetition in the poem. Then poem is against war and also against racial discrimination.

Questions 12 to 16. Read the following passage and answer the questions given. Each question carries one score. (1 × 5 = 5)

I still remember the rush of energy I got from actually leaving the store undetected.

Satyajit Ray took pains to shoot the scene with a tiger for his film ‘Goopy Gyne Bagha Byne’. Prepare a write-up describing the difficulties Ray experienced in shooting the scene. (Hints: contacts Bharat Circus – meets the manager – brings the tiger to the location – tiger springs out – controls – calms down – shoots the scene – too dark – retake)
Answer:
As arranged with Mr. Thorat of Bharat Circus, a lorry arrived with two well-fed tigers. He brought two so that if one did not do things properly the other could be used. Atripod was placed facing the bamboo grove to mount the camera. The audience was instructed to get behind the camera. Goopy and Bagha were placed close to the bamboo grove so that they could be seen along with the tiger.

A five-foot iron rod was fixed to the ground, some 30 feet from the area where the tiger was to walk. A tiger-skin collar with a thin wire inside was placed in the neck of the tiger. The door of the cage was opened and the tiger jumped out. But instead of walking calmly it started running and jumping about. When it became calm some shots were taken. But the shots were later found to be dark owing to poor light.

The scenes had to be shot a second time. A bamboo grove near Calcutta in Boral was found. The lorry arrived with Thorat, the tiger, the steel wire, the special collar and the iron rod. The whole village came to watch the shooting. The villagers were told to keep at least 70 feet away from the scene of the shot. Without listening to the instructions, the entire crowd got as close to the camera as they could.

Thorat opened the cage. With a roar the tiger charged towards the crowd. The crowd disappeared as if my magic. Soon the tiger calmed down and the shots were taken as required. This time the tiger and the camera behaved well.

Answer:
I met Mr John and his wife in a ship as I was returning home after a trip to New York. I noticed a young man was trying to talk to me. It was Mr. John’s wife who persuaded him to come and talk to me.

John lost his parents and so his uncle got him an employment in a London Lawyer’s office. As he was without friends and relatives, he soon fell into bad company and started living beyond his means. He bet on horses and lost all his savings.

He borrowed money which also he lost. He decided to steal some money from his office and make a final gamble. That also he lost. Now he would be caught and jailed and so he decided to commit suicide. He went to his room and left the gas on.

A policeman and the landlady called a doctor to help him. The doctor revived him. The policeman asked him why he decided to kill himself. He said he stole 7 pounds and 10 shillings from the office safe, If that is not returned, he would be caught and jailed.

In his helpless condition, the three present there – the doctor, the landlady and the policemah – decided to help him. The doctor gave him the money to be put back in the safe. The policeman agreed not to report the case. The landlady agreed to give John free board fora month.

Question 25.
Vanka’s Grandfather was sad after he had left the boy at Alyakhin’s work place. He writes his feelings in his diary. Prepare the likely diary entry of the Grandfather.
Answer:
Today is a sad day for me. I have left Vanka with the shoemaker Alyakhin, in Moscow. Vanka will be an apprentice to the shoemaker. I do hope that Alyakhin will treat Vanka properly. I am worried because Vanka is only a 9 year old boy. He is an orphan as his parents have died. In Alyakhin’s place there are other boys who are also apprentices. Those senior boys might rag Vanka and make him do unpleasant things. I have.heard that Alyakhin’s wife is a cruel woman. She also might mistreat Vanka. She has a small baby and maybe she will ask Vanka to take care of that baby.

I think I made a mistake in apprenticing Vanka to Alyakhin. If Vanka were with me he would help me in so many ways. He would help me in the kitchen and in the garden. He could buy things for me. He could take care of my dogs Ka’shtanka and Eel. Eel seemed to love Vanka.

Vanka could grind snuff for me. I remember how he helped me during the last Christmas when I went to the forest to bring a Christmas tree for Miss Olga Ignatevnya. She liked Vanka very much. She used to give him sweets and she taught him to write and read and to count. He too loved her.

I left him with Alyakhin in Moscow for his own welfare. I am 65 years old. I can’t teach Vanka any trade so ; that he can take care of himself when I am no more. It was with this intention I took him to Alyakhin. I only wish Vanka well. I hope he is happy there and will learn the trade of shoe-making so that he can be a successful man later in his life.

Question 27.
Martha was extremely happy on the day she received the Scholarship Jacket. Imagine that she wrote a letter to her friend describing all the incidents that had happened in the school. Prepare the likely letter.
Answer:
St. Andrew’s School,
Texas, USA
10 May 1018

Dearest Ammini,
I received your letter and I am happy to note that you have done well in your studies.

Here in our school, I had a problem. The school had a tradition to award the Scholarship Jacket to the best Standard VIII student for outstanding performance. It is given during the Passing Out Day every year. I worked hard for it. For all the 8 years of my stay in the school I was on top. I was sure that I would get the Jacket.

But things were not as easy as I thought. I overheard a conversation between Mr. Schmidt and Mr. Boone, both my teachers. It made me sad. What I understood was that ttie Management was planning to give Joann, one of my classmates, the Jacket. Joann is the daughter of a member of the School Board.

With the support of some staff members, he wanted to manipulate things so that his daughter would get the scholarship jacket. She was next to me in performance. A new proposal was made to charge 15 dollars from the student eligible for the Award. He knew that my parents could not afford such a sum and naturally Joanne would get the jacket. The Principal had no choice but to agree with the Board’s decision. He asked me to bring 15 dollars.

I requested my grandfather to give me 15 dollars. But he refused to give me the money. He said that a scholarship jacket is not something to be bought. Fortunately for me, some teachers, especially my history teacher Mr. Schmidt supported my case and argued in the staff meeting that I should be given the jacket whether I pay or not.

The Principal had to reverse his earlier decision, and, to cut a long story short, I was given the Jacket. Oh, I am so happy! Ammini, I will visit you during this vacation. Convey my loving regards to your parents and your brother Jose.

Yours lovingly,
Martha

‘A man’s life is shaped by the surroundings in which he lives.’ Imagine you are asked to deliver a speech in the school assembly on this topic. Prepare the speech in the light of the story The Best Investment I Ever Made.’
Answer:
Respected Headmaster, teachers and my dear friends,

Good Morning to you all!

Today I am asked to talk to you on the topic, “A man’s life is shaped by the surroundings in which he lives.” There is no doubt that we are the products of the surroundings in which we live. I can make this very clear by telling you a story written by A. J. Cronin. The story is titled “The Best Investment I Ever Made”. The story is like this: There was a man named John. John lost his parents early in life and so his uncle got him an employment in a London Lawyer’s office.

As he was without friends and relatives, he soon fell into bad company and started living beyond his means. He bet on horses and lost all his savings. He borrowed money which also he lost. He decided to steal some money from his office and make a final gamble. That also he lost. Now he would be caught and jailed and so he decided to commit suicide. He went to his room and turned the gas on.

John was lucky. He did not die. The landlady and the sergeant called a doctor to help him. The doctor soon revived John. The sergeant asked him why he decided to kill himself. He said he stole 7 pounds and 10 shillings from the office safe. If that was not returned, he would be caught and jailed. In his helpless condition, the three present there – the doctor, the landlady and the sergeant – decided to help him.

The doctor gave him the money to be put back in the safe. The sergeant agreed not to report the case. The landlady agreed to give John freeboard for a month. These virtuous acts on the part of his benefactors transformed John. He studies hard and becomes a lawyer and then the director of a charitable organization working for the rehabilitation of maladjusted and delinquent youth.

We see John repaying generosity with generosity. Cronin, the doctor, had made the best investment he had ever made. It is such people that make this world a beautiful place to live in.

Summary
Temperature And Heat
Temperature is a measure of hotness of a body. Heat is a form of energy transferred between two system (or system and surrounding) by virtue of temperature difference. The SI unit of heat is Joule (J) and that of tempera-ture is Kelvin (K).

Measurement Of Temperature
The instrument used to measure temperature is thermometer. The different temperature scales are Kelvin scale, Degree Celsius scale, and Fahrenheit scale. If t1 and tc are temperature in Fahrenheit scale and Celsius scale, then their linear relationship is given by

µ is the number of moles in given gas and R is universal gas constant.
The value of R is 8.31 J mol-1 k-1.
Absolute Temperature:
The minimum value of temperature for ideal gas is – 273.15°C (OK). This temperature is called absolute zero. On kelvin scale -273.15°C is taken as zero point.
Note:
The absolute temperature for a gas can be obtained by extrapolating the pressure versus temperature graph as shown below.

Thermal Expansion
The change in temperature of a body may change its length, area or volume. The fractional change in dimension [ratio of change in dimension to original dimension] is proportional to change in temperature.

The corresponding proportionally constant is called coefficient of thermal expansion or thermal expansivity. Thermal expansion can be defined as ratio of increase in dimension of body to increase in temperature.

There are different three types of thermal expansion, which are shown in the table given below

Question 1.
Derive the following relations

  1. αa = 2αl
  2. αv = 3αl

Answer:
Consider a cube of length ‘l’. Due to the increase in temperature ‘∆T’, length of cube increases by ∆l in all directions.
Coefficient of linear expansion, αl = \(\frac{\Delta \ell}{\ell \Delta \mathrm{T}}\)
1. Increase in area of cube ∆A
= Final area – initial area
= (l + ∆l)2 – l2 = 2 × l × ∆l

Heat capacity (S) of substance is the quantity of heat required to increase the temperature of whole substance.
If ∆Q is the amount of heat required to increase the temperature by ∆T the heat capacity.
Plus One Physics Notes Chapter 11 Thermal Properties of Matter 12
Specific heat capacity:
Specific heat capacity of a substance is defined as amount of heat required to increase temperature of unit mass of substance by one unit.
If ∆Q is amount of heat absorbed by substance of mass m and ∆T is change in temperature, then specific heat capacity is
Plus One Physics Notes Chapter 11 Thermal Properties of Matter 13
The SI unit of specific heat capacity is J Kg-1K-1.
Molar specific heat capacity (C):
Molar specific heat capacity of a substance is the amount of heat required to increase the temperature of 1 mole of substance by one unit.
Its unit is J mol-1 K-1.
If a sample has ‘µ’ moles of substance, then its molar specific heat capacity is given by
Plus One Physics Notes Chapter 11 Thermal Properties of Matter 14
Molar specific capacity are of two types:

  • molar specific capacity at constant volume (CV)
  • molar specific heat capacity at constant pressure (CP).

Plus One Physics Notes Chapter 11 Thermal Properties of Matter

Note:

  • Water has high specific heat capacity. So it is used as coolant in automobile radiators and as a heater in hot water bags.
  • Due to high specific heat capacity of water, land is more warmer than water during daytime.

Calorimetry
Calorimetry means measurement of temperature. Calorimeter is a device used to measure heat. Calorimeter consists of a metallic vessel and a stirrer of same type. The vessel is kept inside a wooden jacket.

The wooden jacket contains insulating mate-rials like glass, wool etc. and hence it prevent heat loss. This jacket has a small opening at top and a thermometer is inserted into this hole.

Change Of State
A transition from one state (solid, liquid or gas) to another state is called change of state. There are four such transitions of state.

Change of stateName of transition
Solid → Liquid
Liquid → gas
Liquid → solid
Solid  → gas (without forming liquid)
Melting
Vapurization
Fusion
Sublimation

Plus One Physics Notes Chapter 11 Thermal Properties of Matter

During change of state, the two different state coexist in thermal equilibrium and temperature remains constant until the completion of change of state.

Melting point:
The temperature at which solid and liquid coexist in thermal equilibrium with each other is called melting point. The melting point decreases with pressure

Boiling point.
The temperature at which liquid and vapour state of substance coexist in thermal equilibrium with each other is called boiling point. The boiling point increases with increase in pressure and it decreases with decrease in pressure.

Regelation
Plus One Physics Notes Chapter 11 Thermal Properties of Matter 15
Take an ice block. Put a metal wire over the ice block and attach 5 kg. blocks at the two ends of wire as shown. Then we can see that the metal wire passes through the ice block to the other side without splitting it.

Explanation: The melting point of ice just below the wire decreases due to increase in pressure. As ice melts wire passes and refreeze (due to decrease in pressure). This process is called regelation.

Question 2.
Cooking is difficult at high altitude. Why?
Answer:
At high altitude, pressure is low. Boiling point decreases with decrease in pressure.

Question 3.
For cooking rice pressure cooker is preferred. Why?
Answer:
In pressure cooker, boiling point of water is increased by increasing pressure. Thus rice can be cooked at high temperature.

Plus One Physics Notes Chapter 11 Thermal Properties of Matter

Question 4.
You might have observed the bubbles of steam coming from bottom of vessel when water is heated. These bubbles disappear as it reaches top of liquid just before boiling and they reach the surface at the time of boiling. Explain the reason?
Answer:
Just before boiling, the bottom of liquid will be warm and at the top, liquid will be cool. So the bubbles of steam formed at bottom rises to cooler water and condense, hence they disappear. At the time of boiling, temperature of entire mass of water will be 100°C. Now the bubbles reaches top and then escape.

1. Latent Heat:
The amount of heat per unit mass transferred during change of state of substance is called latent heat of substance for the process.
Eg: Latent heat of vaporization (Lv), Latent heat of fusion (Lf).
If ‘m’ is quantity of substance which undergoes change of state and Q is amount of heat required, then latent heat
L = \(\frac{Q}{m}\)
Latent heat is characteristic of substance and it depends on pressure. Its unit is JKg-1.

Question 5.
Draw the temperature versus heat diagram for water. Mark the three phases of water (including its change of state).
Give reasons forthe following

  1. The slope of phase line during change of state iszero.
  2. The slope of phase line forthe three phases are different.

Plus One Physics Notes Chapter 11 Thermal Properties of Matter 16
Answer:

  1. During change of state temperature remains constant.
  2. Specific heats of different phases are different.

Question 6.
Burns from steam are usually more serious than boil-ing water. Why?
Answer:
Latent heat of vaporization for water is 22.6 × 105J Kg-1 (ie; 22.6 × 105J heat is required to convert 1 kg of water into steam at 100°C). So at 100°C, steam carries 22.6 × 105J. (more heat than water).

Heat Transfer
Heat transfer occurs due to temperature difference. The three modes of heat transfer are

  1. conduction
  2. convection
  3. radiation.

1. Conduction:
In conduction, heat transfers between two adjacent parts of a body due to temperature difference. Heat conduction can be considered as time rate of heat flow (heat current). At steady state the time rate of heat flow (H) is proportional to temperature difference ∆T area of cross section (A) and inversely proportional to length of conductor (L).

K is called thermal conductivity.
Its unit is JS-1m-1K-1 or Wm-1K-1.

Question 7.
Some cooking pots have copper coating on its bottom. Why?
Answer:
Because of high thermal conductivity of copper, it distributes heat over the bottom of pot very quickly and promotes uniform cooking.

Note: In the house with concrete roof, a layer of insulatiori is made on the ceiling to prevent heat transfer and hence to keep the room cooler.

2. Convection:
In convection, different parts of fluid moves from one point to other. Convection can be natural of forced.
In natural convection when fluid is heated, it expands and becomes less dense. It then rises up and colder part replaces it. This process goes on as a cycle.

Plus One Physics Notes Chapter 11 Thermal Properties of Matter

Question 8.
Explain the reason for sea breeze
Answer:
During the day, land heats up more quickly than water in lake (due to high specific heat capacity of water). The air on the surface of earth gets heated, expands, becomes less dense and rises up. The colder air (wind) replaces the space created by hot air. It creates a sea breeze. At night the land loses its heat very quickly than water. So water remains more warmer at night.
Plus One Physics Notes Chapter 11 Thermal Properties of Matter 18
Note: In forced convection, material is forced to move by pump or by other physical means. Some examples are cooling system of automobile engines, heart that circulate blood throughout our body.

3. Radiation:
In radiation, energy is transferred in the form of electromagnetic radiation called heat radiation. Medium is not required for heat transfer. Earth receives energy from sun by means of radiation.

Thermal radiation:
The electromagnetic radiation entitled by a body by virtue of its temperature is called thermal radiation.

Question 9.
The untensils for cooking purpose are blackened at the bottom. Why?
Answer:
This is to absorb maximum heat from fire and hence to fast up cooking.

4. Black body radiation:
Black body:
A black body is one which absorbs radiations of all wavelengths incident on it. When a black body is heated it will emit radiations of all possible wavelengths. The wavelengths emitted by a perfect black body are called black body radiations.
Energy distribution in a black body radiation:
Plus One Physics Notes Chapter 11 Thermal Properties of Matter 19

Plus One Physics Notes Chapter 11 Thermal Properties of Matter
Lummer and Pringsheim performed an experiment to study the distribution of energy (among the radiation emitted by a black body) at different temperatures.
Result of experiment:
1. Fora given temperature the energy distribution is not uniform.

2. The energy associated with both longer and shorter wavelength of radiation emitted is small.

3. For each temperature there exists a particular wavelength corresponding to which the energy associated is maximum (λm).

4. This maximum energy carrying wavelength (λm) decreases with an increase in temperature of the black body.
Plus One Physics Notes Chapter 11 Thermal Properties of Matter 20

5. The area under each curve represents the total energy emitted by the body at a particular temperature.

This area increases with increase of temperature. It is found that area is directly proportional to the fourth power of absolute temperature,
ie. E a T4
Wein’s displacement law:
Wein’s displacement law states that the product of the wavelength corresponding to maximum energy (λm) and the absolute temperature of black body is constant.
ie. λmT = constant
The value of the constant (Wein’s constant) is 2.9 × 10-3mK.
This law explains why the colour of a piece of iron heated in a hot flame first becomes dull red, then reddish yellow and finally white hot.

Wein’s law is useful for estimating the surface temperatures of moon, sun and other stars. If red and blue stars emit radiations of continuous wavelengths, then blue star is hotter than red star.

Stefan’s law of radiation:
Stefan’s law states that the total radiant energy emitted persecond from unit area of the surface of a black body is directly proportional to the fourth power of its absolute temperature.
E a T4
E = sT4

Green house effect:
The earth surface is a source of thermal radiation because it absorbs energy received from sun. The wavelength of this radiation lies in the infrared region. But a larger portion of this radiation is absorbed by greenhouse gases, (CO2, CH4, etc).

This heats up the atmosphere. The net result is heating up of earths surface and atmosphere. This is known green house effect.

Plus One Physics Notes Chapter 11 Thermal Properties of Matter

Newtons laws of cooling
According to Newton’s law of cooling the rate of loss of heat is directly proportional to difference of temperature between the body and its surroundings.
Plus One Physics Notes Chapter 11 Thermal Properties of Matter 21
T1 is temperature of surrounding medium and T2 is temperature of body. K is constant that depends on nature of surface and area of exposed surface.
Note:

  • The law is applicable for small temperature difference.
  • For small temperature difference, cooling occurs due to a combination of conduction, convection, and radiation.
  • The graph between difference in temperature and time is as shown in figure.

उत्तर:
(a)
Kerala SSLC Hindi Previous Year Question Paper March 2019 2

(b) जलसंरक्षण जल जीवन का आधार है। यह जीवों की आधारभूत आवश्यकता है। ऐसा कहा जाता है कि दुनिया में धरती की तुलना में जल की मात्रा अधिक है। लेकिन पीने योग्य पानी की मात्रा बहुत कम है। कुओं, तालाब, नदी, नाले आदि हमारे मुख्य जलस्रोत होते हैं। स्वार्थ के वश में पड़कर मनुष्य हमारे जलस्रोतों का नष्ट करता जा रहा है।

प्रदूषण की वजह से जलस्रोतों का नाश होता जा रहा है। जलस्रोतों का संरक्षण हर मानव का कर्तव्य है। जलसंरक्षण से यदि हम मुँह मोड़ें तो हमारा भविष्य खतरे में पड़ जाएंगे। हमें यह याद रखना चाहिए कि आनेवाली पीढ़ी को इस धरती में जीना है तो जल संरक्षण का कार्य अपने कंधे पर उठाना ही चाहिए। “जल नहीं तो कल नहीं” – यह बिलकुल सही है।

Kerala Plus One Zoology Notes Chapter 2 Animal Kingdom

BASIS OF CLASSIFICATION:
The fundamental features used in animal classification are:

  1. Arrangement of cells
  2. body symmetry
  3. nature of coelom
  4. patterns of digestive
  5. circulatory or reproductive systems.

Plus One Zoology Notes Chapter 2 Animal Kingdom

Levels of Organisation:

In sponges, the cells are arranged as loose cell aggregates, i.e. they exhibit cellular level of organisation. Some division of labour (activities) occur among the cells.
In Echinoderms and Chordates, organs are associated to form functional systems, it is concerned with a specific physiological function. This is called organ system level of organisation.

For example, the digestive system in Platyhelminthes has only a single opening to the outside of the body that serves as both mouth and anus, and is hence called incomplete. A complete digestive system has two openings, mouth and anus.
The circulatory system are of two types:

(i) Open type in which the blood is pumped out of the heart and the cells and tissues are directly bathed in it.
(ii) Closed type in which the blood is circulated through a series of vessels of varying diameters (arteries, veins and capillaries).

Symmetry:
Animals can be categorised on the basis of their symmetry.

Sponges are asymmetrical, i.e., any plane that passes through the centre does not divide them into equal halves
When any plane passing through the central axis of the body divides the organism into two identical halves, it is called radial symmetry. eg: Coelenterates, ctenophores and echinoderms
Animals like annelids, arthropods, etc. where the body is divided into identical left and right halves in only one plane, It is called bilateral symmetry.

Plus One Zoology Notes Chapter 2 Animal Kingdom

Diploblastic and Triploblastic Organisation:

Animals in which the cells are arranged in two embryonic layers, an external ectoderm and an internal endoderm, are called diploblastic animals, eg: coelenterates.
An undifferentiated layer, mesoglea, is present in between the ectoderm and the endoderm. The developing embryo has a third germinal layer, mesoderm, in between the ectoderm and endoderm, they are called triploblastic animals eg: platyhelminthes to chordates

Plus One Zoology Notes Chapter 2 Animal Kingdom 1

Coelom:
The body cavity, which is lined by mesoderm is called coelom. Animals possessing coelom are called coelomates e.g.annelids, molluscs, arthropods, echinoderms, hemichordates and chordates. In some animals, the body cavity is not lined by mesoderm, instead, the mesoderm is present as scattered pouches in between the ectoderm and endoderm.

Such animals are called pseudocoelomates, eg: aschelminthes. The animals in which the body cavity is absent are called acoelomates, eg: platyhelminthes
Plus One Zoology Notes Chapter 2 Animal Kingdom 2

Segmentation:

In some animals, the body is externally and internally divided into segments. For example, in earthworm, the body shows this pattern called metameric segmentation and the phenomenon is known as metamerism.

Notochord:
Notochord is a mesodermally derived rod-like structure formed on the dorsal side during embryonic development in some animals. Animals with notochord are called chordates and those animals which do not form this structure are called non-chordates, eg: porifera to echinoderms.

CLASSIFICATION OF ANIMALS:
Plus One Zoology Notes Chapter 2 Animal Kingdom 3

Plus One Zoology Notes Chapter 2 Animal Kingdom

Phylum – Porifera:
Members are commonly Known as sponges. They are marine and asymmetrical animals. These are primitive multicellular animals and have cellular level of organisation.

  1. Sponges have a water transport or canal system. Water enters through minute pores (ostia) in the body wall into a central cavity, spongocoel (Choanocytes or collar cells line the spongocoel and the canals), from where it goes out through the osculum.
  2. This pathway of water transport is helpful in food gathering, respiratory exchange and removal of waste.
  3. Digestion is intracellular. The body is supported by a skeleton made up of spicules or spongin fibres.
  4. Sexes are not separate (hermaphrodite)
  5. Sponges reproduce asexually by fragmentation
  6. Fertilisation is internal and development include larval stage which is.morphologically distinct from the adult.

Examples: Sycon (Scypha), Spongilla (Fresh water sponge) and Euspongia (Bath sponge).
Plus One Zoology Notes Chapter 2 Animal Kingdom 4

Phylum – Coelenterata (Cnidaria):
They are aquatic, marine and radially symmetrical animals
1. The name cnidaria is derived from the cnidoblasts or cnidocytes present on the tentacles and the body. Cnidoblasts are used for anchorage, defense and for the capture of prey.

2. Cnidarians are dipioblastic animals. They have a central gastrovascular cavity with a single opening, hypostome.

3. Digestion is extracellular and intracellular. For example , corals have a skeleton composed of calcium carbonate.

4. Cnidarians exhibit two basic body forms called polyp and medusa

Plus One Zoology Notes Chapter 2 Animal Kingdom 5

Structure of polyp and medusa:
Polyps are sessile and cylindrical form eg: Hydra, Adamsia, etc. whereas, medusa are umbrella-shaped and free-swimming like Aurelia or jelly fish. They exhibit alternation of generation (Metagenesis), i.e. polyps produce medusae asexually and medusae form the polyps sexually (eg: Obelia).

Examples: Physalia (Portuguese man-of-war), Adamsia (Sea anemone),Pennatula (Sea-pen), Gorgonia (Sea-fan) and Meandrina (Brain coral).

Phylum – Ctenophora:
They incude sea walnuts or comb jellies are marine, radially symmetrical, dipioblastic organisms with tissue level of organisation.

  1. The body bears eight external rows of ciliated comb plates, which help in locomotion
  2. Digestion is both extracellular and intracellular.
  3. Bioluminescence is well-marked in ctenophores.
  4. Sexes are not separate. Reproduction takes place only by sexual means.
  5. Fertilisation is external with indirect development.

Examples: pleurobrachia and ctenoplana.

Phylum – Platyhelminthes:

  1. They have flattened body and called as flatworms
  2. Flatworms are bilaterally symmetrical, triploblastic and acoelomate animals with organ level of organisation.
  3. Hooks and suckers are present in the parasitic forms. Some of them absorb nutrients from the host directly through their body surface.
  4. Specialised cells called flame cells help in osmoregulation and excretion.
  5. Sexes are not separate.
  6. Fertilisation is internal and development is through many larval stages. Some members like Planaria possess high regeneration capacity.

Examples: (a) Taenia (Tapeworm), (b) Fasciola (Liver fluke).
Plus One Zoology Notes Chapter 2 Animal Kingdom 8

Phylum – Aschelminthes:
The body is circular and called as roundworms. They may be freeliving, aquatic and terrestrial or parasitic in plants and animals.

  1. Roundworms have organ-system level of body organisation.
  2. They are bilaterally symmetrical, triploblastic and pseudocoelomate animals.
  3. Alimentary canal is complete and called as muscular pharynx. An excretory tube removes body wastes from the body cavity through the excretory pore.
  4. Sexes are separate (dioecious)
  5. Fertilisation is internal and development may be direct or indirect.

Examples Ascaris (Round Worm), Wuchereria (Filaria worm), Ancylostoma (Hookworm).

They may be aquatic (marine and fresh water) orterrestrial; free-living, and sometimes parasitic.

  1. They exhibit organ-system level of body organisation and bilateral symmetry. They are triploblastic, metamerically segmented and coelomate animals.
  2. Their body surface is distinctly marked out into segments or metameres and hence, the phylum called as Annelida.
  3. Aquatic annelids like Nereis possess lateral appendages, parapodia, which help in swimming.
  4. A closed circulatory system is present.
  5. Nephridia help in osmoregulation and excretion.
  6. Neural system consists of paired ganglia connected by lateral nerves to a double ventral nerve cord.
  7. Nereis, an aquatic form, is dioecious, but earthworms and leeches are monoecious.
  8. Reproduction is sexual. Examples: Nereis, Pheretima (Earthworm) and Hirudinaria (Blood sucking leech).

Plus One Zoology Notes Chapter 2 Animal Kingdom 16

Phylum Chordata is divided into three subphyla:

  1. Urochordata or Tunicata
  2. Cephalochordata &
  3. Vertebrata.

In Urochordata, notochord is present only in larval tail, while in Cephalochordata, it extends from head to tail region. Examples: Urochordata – Ascidia, Salpa.Doliolum; Cephalochordata – Branchiostoma (Amphioxus or Lancelet).
Plus One Zoology Notes Chapter 2 Animal Kingdom 17

All vertebrates are chordates but all chordates are not vertebrates.why?
The members of subphylum Vertebrata possess notochord during the embryonic period. The notochord is replaced by a cartilaginous or bony vertebral column in the adult. Thus all vertebrates are chordates but all chordates are not vertebrates.

Vertebrates have a ventral muscular heart with two, three or four chambers, kidneys for excretion and osmoregulation and paired appendages which may be fins or limbs.

State what do you understand by accounting reports?
Answer:
An accounting report is basically the physical form of accounting information. Accounting reports are reports which display information that is acquired from data processing and transformed in an organised manner. Here it is worth mentioning that a report is prepared with a definite objective.

Every report is a collection of related information for a particular need and purpose and must meet the twin objectives of reporting; First to reduce the level of uncertainty that is faced by a decision-maker; second to influence the behaviour (or positive actions) of the decision-maker.

Question 3.
What do you mean by Query in Access. Name the types of queries.
Answer:
A query is a request for data or information from a database table. This data may be generated as results returned by structured query language (SQL) or as pictorials, graphic or complex results.
A query is used to extract data from a database in a readable format according to the users request.
Types of queries:
There are several types of queries in access that are used to generate information. Such queries are called “select queries” because they are used to “select” records with a given set of fileds. There are three types of queries.

  1. Simple query
  2. Parameter queries
  3. Summary queries

Question 4.
With the help of an example, briefly state the meaning of parameter queries.
Answer:
A parameter Query is a query that asks you for one or more pieces of information before displaying the data sheet. A parameter query prompts the user to enter Parameters, or criteria through an input box, for selecting a set of records.

A parameter query is useful when there is a need to repeat the same query with different criteria. The criteria, is not constant as in the case of the simple query. While extracting the transactions to prepare ledger accounts, the same set of queries need to be executed for different account codes. Consider the following SQL statement.

Question 1.
What do you mean by programmed and casual reports?
Answer:
Accouting information, generated by processing accounting data is gathered to generate an accounting report. An accounting report, in order to be useful, must display information context in such a manner so as to give confidence to the user, influence his behaviour and prompt him to take positive action. Accounting reports can be classified into two broad categories ie. Programmed Report and Casual Report.
1. Programmed Reports:
Programmed reports are reports which contain information useful for decision making in those situations which the users have anticipated to occur. There are two types of reports within this report type.

a. Scheduled Reports:
The reports, which are produced according to a given time frame, are called scheduled reports. The time frame may be daily, weekly, monthly, quarterly or yearly. Some Statement of Cash transactions (Cash book), Statement of Ageing Accounts, Closing Stock Report, Profit and Loss Account and Balance Sheet, etc.

b. On-Demand Reports:
The reports, which are generated only on the triggering of some event, are called on demand reports. Some examples of an demand reports are a Customer’s Statement of Account, Inventory Reorder Report, Stock in hand Report for a Selected Group of items, etc.

2. Casual Reports:
Casual reports are those reports, the need for which is not anticipated, the information content of which may be useful but casually required. These adhoc reports and are generated casually by executing some simple queries without requiring much of professional assistance. As opposed to programmed reports, casual reports are generated as and when required.

Describe and discuss the procedure of creating the receipts side of a cash book.
Answer:
As it is known to all a Cash book is a type of accounting report. The procedure of creating the receipts side of cash book is same as reports generation. In the process of producing receipts side of a cash book, it is necessary to retrieve a set of processed data records which provide information on code (Account Number), Name of Account, Particulars and credit Balance with reference of each account where cash account is debited.

Receipt side of cash book deals with the cash receipts. In the process of creating receipts side we have to find out the amount and particulars of the transaction in which cash is received ie. cash account is debited. For creating it, first we have to find out these amounts and a particular set of SQL statement and save them into Database after giving particular name to each query.

After creating the SQL statement now we will start the process of MS Access Database. Select create report in design view and query (Last Saved). This respond to give blank report design dividend into three sections page header, detail and page footer and of available fields of Query.

Here, we design our report with the tools provided by Access like giving name to the report, defining its size and colour. After this we select the all fields from our Query and drag and drop them into the Detail section. By applying some arithmetical calculations provided by Access we get the receipt, side of cash book.

Question 4.
Discuss with a set of inter-related data tables, the basics of creating queries in MS Access?
Answer:
It is a well know fact that Relational Database management system stores data in different table (relations) so that there is no or minimum data redundancy. But for a complete view of data stored across various tables is achieved only by executing Queries based on SQL. A query is capable of displaying record containing field from across a number of data tables.

In other words SQL has statement for data defini-tion, query and update. Besides this, it has the ca-pability to define user oriented views of database; specify security and authorisation, define integrity constraints and various other operations. Various SQL statements are used to create queries for inter-related data tables.

1. Select Queries from Objects list given in LHS of database window. Double click at Create Query by Using Design View given on the RHS.

2. Access responds by displaying a Select Query and Show Tables Window. The select query window is vertically divided into two panes, upper pane and lower pane. The upper pane is meant to display data sources (Tables or Existing Queries) and the lower pane, which is also called Query By Example (QBE) grid, has one column each for field to be included in query being created.

The row of this grid shows field name, table (or query), sort order, whether the selected field is shown in the query results or not and also the criteria that have been applied to the field or fields to restrict the query results.

The Show Table Window is meant to add tables, queries or both to the upper pane of Select Query Window. If closed, the show Table Window can be recalled by a right click at upper pane % show table.

3. Click at View item of Menu bar % Total and then % Table Names.

4. Click at field row of first column of QBE grid to select the fields to be included in the query. The process is repeated for second and subsequent columns of grid to include more fields in the query. This process of selection constitutes the data items to be displayed by SELECT clause of SQL statement.

5. The name of table or query is displayed, in accordance with selection of fields. Such tables or queries constitute the data sources shown after FROM clauses of SQL statement. However, the initial selection a table/ query in the second row of QBE grid restricts the choice of fields to the selected table/query only.

6. Click at row of grid to specify the Group by clause and aggregate functions so that a summary query is created.

7. Click at row of grid to specify the sort order (Ascending or descending) on field(s). The selected fields for sort order are shown after ORDER BY clause of SQL statement in which ascending order is the choice of default.

8. Click at row to check for the selected field to be displayed in the query result. The field(s) may be selected only for the purpose of specifying the sort order or criteria.

9. Click at row ofthe grid to specify the criteria to limit the records to be displayed by the query being created. The specified criteria result in a conditional expression, which is shown after the WHERE clause of SQL statement.

10. Click File % Save (or Press Ctrl + S) to save a query. A dialog box prompts the user to specify the name of the query being created. By default a generic name appears which can be accepted or rewritten with a desired name.

Question 3.
Explain MS Access and its components.
Answer:
MS Access is one of the popularly used Database Management System (DBMS) to create, store and manage database. It is popularly called Access. Access is functionally available with the following seven object classes. Each of these object classes is capable of creating their respective object replicas.

  1. Tables: This object class allows a database designer to create the data tables with their respective field names, data type, and properties.
  2. Queries: The stored data is processed using the query facility to produce desired information.
  3. Forms: This object class allows the designer to create an appropriate user interface to formally interact with back end database defined by the tables and queries.
  4. Reports: This object class is used to create various reports. Such reports are designed in access according to the requirement of end user.
  5. Pages: This object class is meant to create data access pages which can be posted on a website of an organisation using internet.
  6. Macros: A macro is a list of macro-oriented actions that runs as a unit.
  7. Modules: These are the foundation of any application and allow the designer to create a set of programming instructions called functions or sub-routines that can be used throughout the application.

Question 1.
Discuss the SQL view method of creating a query.
Answer:
SQL View Method:
A query may be directly specified in Select Query Pane by a right click at table pane % SQL view. The upper and lower panes of selected query window are substituted by a pane to specify the SQL Statement that is written by using keyboard.

The desired SQL statement is directly okeyed in on this pane and saved in the same manner as described for design method. While forming the SQL statement, the following clauses are normally used for generating information (or Select) queries.

1. SELECT:
This clause is used to specify the fields to display data or information. Consider the following SQL statement segment.
SELECT code, Name, Amount
The fields Code, Name and Amount after SELECT clause indicate the data items to be displayed by the query statement.

2. FROM:
This clause is meant to indicate the source of data in terms of tables or queries or a combination of both. Two tables are joined by specifying a JOIN Clauuse based on a condition of Join. There can be three types of Join, Inner, Left and Right.

3. INNER:
This join clause is meant to display only exactly matching records between two data sources. Consider the following SQL statement segment.
FROM Accounts INNER JOIN Account Type
ON (Catld = Type)
In the above statement, only those records of Accounts and Account Type table constitute the source of query data, which match exactly on Catld = Type.

4. LEFT:
With this Join, all the records in the primary table in the relationship are displayed irrespective whether there are matching records in the related table or not. Consider the following SQL statement segment.
FROM Accounts LEFT JOIN Account Type
ON (Catld = Type)
In the above statement, all records of Accounts along with matching records of Account Type table constitute the source of query data, the matching condition is Catld = Type.

5. RIGHT:
With this join, all the records of related table in the relationship are displayed irrespective whether there are matching records in the primary table or not. Consider the following SQL statement.
FROM Accounts RIGHT JOIN Account Type
ON (Catld = Type)
In the above statement, all records of Account Type along with matching records of Accounts table constitute the source of query data. The matching condition is Catld = Type.

6. WHERE:
This clause in SQL statement is used to provide the condition to restrict the records to be returned by query. The resultant records of query must satisfy the condition which is specified after WHERE clause. This is meant to filter records returned by the query.

Plus One Accountancy Chapter Wise Questions and Answers Chapter 12 Accounting System Using Database Management System

7. ORDER BY:
This clause is meant to specify the order in which the resultant records of query are required to appear. The basis of ordering is determined by the list of fields specified after the order by clause. Consider the following SQL statement segment.
ORDER BY Type, Code
The above statement in the context of Accounts table implies that the resultant record set is ordered by the Type field of Accounts and within Type, by Code field of Accounts.

8. GROUP BY:
The group by clause is used in the SQL statement to enable grouping of records for creating summary query. The fields after GROUP BY clause constitute the basis of grouping for owhich summary results are obtained. Consider the following SQL statement.
Plus One Accountancy Accounting System Using Database Management System Eight Mark Questions and Answers 15
In the above SQL statement, the GROUP BY clause uses Debit account codes as the basis for computing the sum of amount of voucher. The total amount, by which every transacted account has been debited, is given by this SQL statement. In this statement, sum of amount is found for each group of records formed using GROUP BY clause.

Question 2.

Answer:
Model II:
The following series of SQL statements retrieve the record set for producing trial balance when database design for Model-ll is used. In addition to this, the accounts have been categorised within the trial balance according to the Account Type: Expenses, Revenues, Assets, and Liabilities.

1. To find the Total Amount by which the Accounts have been Debited:
The transacted accounts in design of Model-ll have been stored in AccCode of Vouchers Main and Code of Vouchers Detail:
The following SQL statement is formed to generate the relevant information from Vouchers Details.

Both the SQL statements are meant to extract similar sets of records, but from different sources. Therefore, the resultant record set of these SQL statements have been horizontally merged using UNION clause as shown below.
Plus One Accountancy Accounting System Using Database Management System Eight Mark Questions and Answers 19
The above SQL statement is saved as Query 101 for its subsequent use. The total of debit amount in this query represents the Total with positive amounts.

2. To find the Total Amount by which the accounts have been credited:
In order to ascertain the total amount by which every transacted account has been credited, a query similar to that in (a) need to be formed.

This is achieved by substituting Debitfield in SELECT and GROUP BY clause by Credit field and the sum of amount generated by sum(Amount) is multiplied by -1 so that the final amount assigned to Total field is always negative. Accordingly, the following SQL statement is formed.
Plus One Accountancy Accounting System Using Database Management System Eight Mark Questions and Answers 20

Plus One Accountancy Chapter Wise Questions and Answers Chapter 12 Accounting System Using Database Management System
In the above SQL statement, the sum of amount has been multiplied by -1 to ensure that the amount of credit is always negative just as amount of debit is taken as positive. This query is saved as Query 102 for its subsequent use.

3. To find a collective record set of Accounts with their Debit and Credit totals:
A collective record set is generated by forming a union query between Query 101 and Query 102 to ensure that the debit and credit amount with respect to each account becomes available for generating the net amount.
Accordingly, the following SQL statement is formed.

WHAT IS ‘LIVING’?
The features of living organisms are

Growth, reproduction, ability to sense environment etc.

Plus One Zoology Notes Chapter 1 The Living World

All living organisms grow, increase the mass and increase the number of individuals are the characteristics of growth.

  • In plants, growth by cell division occurs continuously throughout their life span.
  • In animals, growth is seen only up to a certain age.
  • Unicellular organisms also grow by cell division it can be seen in in-vitro cultures by simply counting the number of cells under the microscope.
Reproduction, likewise, is a characteristic of living organisms.
  • In multicellular organisms, reproduction refers to the production of progeny possessing features more or less similar to those of parents.
  • Fungi multiply and spread due to the millions of asexual spores they produce.
  • In lower organisms like yeast and hydra reproduce by budding.
  • In Planaria (flatworms) a fragmented organism regenerates the lost part of its body and becomes a new organism.
  • The fungi, the filamentous algae, the protonema of mosses etc multiply by fragmentation.
Another characteristic of life is metabolism.

All living organisms are made of chemicals. These chemicals are constantly being made and changed into some other biomolecules. There are thousands of metabolic reactions occurring simultaneously inside all living organisms.

Metabolism is a defining feature of all living organisms without exception, isolated metabolic reactions in vitro are not living things but surely living reactions.

Hence Cellular organisation of the body is the defining feature of life forms
  • All organisms, from the prokaryotes to the most complex eukaryotes can sense and respond to environmental cues.
  • Photoperiod affects reproduction in seasonal breeders, both plants and animals.
  • All organisms are ‘aware’ of their surroundings.
  • Human being is the only organism who is aware of himself, i.e. self-consciousness.
Consciousness therefore, becomes the defining property of living organisms.

Living organisms are self-replicating, evolving and self-regulating interactive systems capable of responding to external stimuli. All living organisms are linked to one another by the sharing of the common genetic material, but to varying degrees.

DIVERSITY IN THE LIVING WORLD:

The number of species comes to the range between 1.7 – 1.8 million. This refers to biodiversity of organisms on earth.

Nomenclature:
There are millions of plants and animals in the world; their names need to be standardised all overthe world. This process is called nomenclature.

Identification:
Nomenclature or naming is only possible when the organism is described correctly and the name is attached to. This is identification.

For plants, scientific names are based on agreed principles and criteria, which are provided in International Code for Botanical Nomenclature (ICBN). For animals International Code of Zoological Nomenclature (ICZN). Biologists follow universally accepted principles to provide scientific names.

Each name has two components – the Generic name and the specific epithet. This type of naming with two components is called Binomial nomenclature. This was given by Carolus.

For example the scientific name of mango is written as Mangifera indica. In this name Mangifera represents the genus while indica, is a particular species, or a specific epithet Other universal rules of nomenclature are as follows:

1. Biological names are generally in Latin and written in italics.
2. The first word in a biological name represents the genus while the second is the specific
3. The first word denoting the genus starts with a capital letter while the specific epithet starts
with a small letter
4. Name of the author appears after the specific epithet, eg: Mangifera indica Linn. It indicates that this species was first described by Linnaeus

Classification:
It is the process by which anything is grouped into categories based on some easily observable characters. Hence, based on characteristics, all living organisms can be classified into different taxa. This process of classification is taxonomy.

Hence, characterisation, identification, classification and nomenclature are the processes that are basic to taxonomy. Sytematics include identification, nomenclature and classification. It also takes into account evolutionary Ktogdom relationships between organisms.

The word systematics is derived from the Latin word ‘systems’ which means systematic arrangement of organisms. Linnaeus used Systems Naturae as the title of his publication.

TAXONOMIC CATEGORIES:
It involves hierarchy of steps that represents a rank or category. Since all categories together constitute the taxonomic hierarchy. Each category, referred to as a unit of classification termed as taxon Insects represent a group of organisms sharing common features like three pairs of jointed legs. It means insects are recognisable give the rank. Each rank or taxon represents a unit of classification.

Common categories as kingdom, phylum or division (for plants), class, order, family, genus and species. In the plant and animal kingdoms species is lowest category.This helps in identifying similarities and dissimilarities among the individuals of the same kind of organisms as well as of Other kinds of organisms.
Plus One Zoology Notes Chapter 1 The Living World 1

Species:
The group of individual organisms with fundamental similarities are called species. The species distinguish from other closely related species based on the distinct morphological differences.

For example Mangifera indica, Solanum tuberosum (potato) and Panthera leo (lion). All the three names, indica, tuberosum and leo, represent the specific epithets, while the first words Mangifera, Solanum and Panthera are genera.

Genus:
Genus comprises a group of related species which has more common characters For example, potato, tomato and brinjal are three different species but all belong to the genus Solanum. Lion (Panthera leo), leopard (P pardus) and tiger (P. tigris) with several commodes features are all species of the genus Panthera.

Family:
Family, has a group of related genera with number of similarities. Families are characterised on the basis of both vegetative and reproductive features of plant species.

Solanum, Petunia and Datura are placed in the family Solanaceae. Genus Panthera, comprising lion, tiger, leopard is put along with genus, Fells (cats) in the family Felidae

Plus One Zoology Notes Chapter 1 The Living World

Order:
Order is the assemblage of families which exhibit a few similar characters. The similar characters are less in number as compared to different genera included in a family.

Plant families like Convolvulaceae, Solanaceae are included in the order polymoniales mainly based on the floral characters. The animal order, Carnivora, includes families like Felidae and Cancidae.

Class:
This category includes related orders. For example, order Primata comprising monkey, gorilla and gibbon is placed in class Mammalia The order Carnivora that includes animals like tiger, cat and dog belongs to the Class Mammalia also.

Phylum:
It includes animals like fishes, amphibians, reptiles, birds along with mammals.

They have common features like presence of notochord and dorsal hollow neural system, are included in phylum Chordata.

In the case of plants, classes with a few similar characters are placed in the category called Division.

Kingdom:
All animals belonging to various phyla are assigned to the highest category called Kingdom Animalia The Kingdom Plantae, comprises all plants from various divisions.

The taxonomic categories starting with species and ends in kingdom are arranged in ascending order. From species to kingdom, the number of common characteristics goes on decreasing.

TAXONOMICAL AIDS:
The collection of specimens of plant and animal species is essential for taxonomic studies. These are also fundamental to systematics.

Herbarium:
It is a store house of collected plant specimens that are dried, pressed and preserved on sheets. These sheets are arranged according to a universally accepted system of classification. The descriptions on herbarium sheets, become a store house or repository for future use.

The herbarium sheets also carry a label providing information about date and place of collection. Herbaria also serve as quick referral systems in taxonomical studies.
Plus One Zoology Notes Chapter 1 The Living World 2

Botanical Gardens:
These are the collections of living plants for reference. Plant species in these gardens are grown for identification purposes. and each plant is labelled indicating its botanical/scientific name and its family.

The famous botanical gardens are at Kew (England), Indian Botanical Garden, Howrah (India) and at National Botanical Research Institute, Lucknow (India).

Museum:
Museums have collections of preserved plant and animal specimens for study and reference. Specimens are preserved in the containers or jars in preservative solutions. Plant and animal specimens may also be preserved as dry specimens.

Insects are preserved in insect boxes after collecting, killing and pinning. Larger animals like birds and mammals are usually stuffed and preserved. Museums have collections of skeletons of animals also.

Zoological Parks:
These are the places where wild animals are kept in protected environments under human care that helps to learn about their food habits and behavior.

Key:
It is used for identification of plants and animals based on the similarities and dissimilarities. The keys are based on the contrasting characters in a pair called couplet. The choice made between two opposite options results in the acceptance and rejection.

Plus One Zoology Notes Chapter 1 The Living World

Each statement in the key is called a lead. Separate taxonomic keys are required for each taxonomic category such as family, genus and species for identification purposes. Flora, manuals, monographs and catalogues help in correct identification.

Flora contains the actual account of habitat and distribution of plants of a given area.
Manuals are useful in providing information for identification of names of species found in an area.
Monographs contain information on any one taxon.
