Question:1

An ideal gas undergoes four different processes from the same initial state (Figure). Four processes are adiabatic, isothermal, isobaric and isochoric. Out of 1, 2, 3 and 4 which one is adiabatic.


(a) 4
(b) 3
(c) 2
(d) 1

Answer:

The answer is the option (c) 4 is the isobaric process, 1 is isochoric. Out of 3 and 2, 3 has a smaller slope hence is isothermal. Remaining process 2 is adiabatic.

Question:2

If an average person jogs, he produces 14.5 \times 10^{3} cal/min. This is removed by the evaporation of sweat. The amount of sweat evaporated per minute (assuming 1 kg requires 580 \times 10^{3} call for evaporation) is
(a) 0.025 kg
(b) 2.25 kg
(c) 0.05 kg
(d) 0.20 kg

Answer:

The answer is the option (a) 0.025 kg

\text{Amount of sweat produced}=\frac{14.5\times10^3}{580\times10^3}=0.025Kg

Question:3

Consider P-V diagram for an ideal gas shown in Figure.

Out of the following diagrams (Figure), which represents the T-P diagram?



(a) (iv)
(b) (ii)
(c) (iii)
(d) (i)

Answer:

The answer is the option (c)

Question:4

An ideal gas undergoes cyclic process ABCDA as shown in given P-V diagram (Figure). The amount of work done by the gas is

a) 6P_{0}V_{0}
b) -2P_{0}V_{0}
c) +2P_{0}V_{0}
d) +4P_{0}V_{0}

Answer:

The answer is the option (b). Since the direction of arrows is anticlockwise, so work done is negative equal to the area of the loop
=-2P_{0}V_{0}

Question:5

Consider two containers A and B containing identical gases at the same pressure, volume and temperature. The gas in container A is compressed to half of its original volume isothermally while the gas in container B is compressed to half of its original value adiabatically. The ratio of final pressure of gas in B to that of gas in A is
a) 2^{\gamma-1}
b) \left (\frac{1}{2} \right )^{\gamma-1}
c) \left (\frac{1}{1-\gamma} \right )^{2}
d) \left (\frac{1}{\gamma-1} \right )^{2}

Answer:

The answer is the option (a). Let us consider a P-V diagram for container A and B. Compression of gas is involved in both the cases. For the isothermal process (gas A) during 1\rightarrow 2

P_1V_1=P_{2}V_{2}

P_{0}(2V_{0})=P_{2}V_{0}

P_{2}=2P_{0}
For adiabatic process 1\rightarrow 2
P_{1}V_{1}^{\gamma }=P_2V_{2}^{\gamma}

P_{0}(2V_{0})^{\gamma }=P_{2}(V_{0})^{\gamma }

P_{2}=\left (\frac{2V_{0}}{V_{0}} \right )^{\gamma} P_{0}=2^{\gamma } P_{0}

\frac{(P_{2})_{B}}{(P_{1})_{A}}=\frac{2^{\gamma } P_{0}}{2P_{0}}=2^{\gamma -1}

Question:6

Three copper blocks of massesM_{1}, M_{2} and M_{3} kg respectively are brought into thermal contact till they reach equilibrium. Before contact, they were at T_{1}, T_{2}, T_{3} (T_{1} > T_{2} > T_{3} ). Assuming there is no heat loss to the surroundings, the equilibrium temperature T is (s is specific heat of copper)

a) T=\frac{T_{1}+T_{2}+ T_{3}}{3}
b) T=\frac{M_{1}T_{1}+M_{2}T_{2}+ M_{3}T_{3}}{M_{1}+M_{2}+M_{3}}
c) T=\frac{M_{1}T_{1}+M_{2}T_{2}+ M_{3}T_{3}}{3(M_{1}+M_{2}+M_{3})}
d) T=\frac{M_{1}T_{1}s+M_{2}T_{2}s+ M_{3}T_{3}s}{M_{1}+M_{2}+M_{3}}

Answer:

The answer is the option (b) Let the equilibrium temperature of the system=T
Let T_{1}T_{2}<T<T_3
As there is no loss to the surroundings.
Heat lost by M_3=Heat gain by M_{1}+Heat gain by M_{2}
M_{3}s(T_{3}-T)=M_{1}s(T-T_{1})+M_{2}s(T-T_{2})
M_3sT_3-M_3sT=M_1sT-M_1sT_1+M_2sT-M_2sT_2
T(M_{3}+M_{1}+M_2)=M_3T_3+M_1T_1+M_2T_2
T=\frac{M_1T_1+M_2T_2+M_{3}T_{3}}{M_{1}+M_2+M_3}
Hence (b) is correct.

Question:7

Which of the processes described below are irreversible?
(a) The increase in temperature of an iron rod by hammering it.
(b) A gas in a small container at a temperature T1 is brought in contact with a big reservoir at a higher temperature T2 which increases the temperature of the gas.
(c) A quasi-static isothermal expansion of an ideal gas in a cylinder fitted with a frictionless piston.
(d) An ideal gas is enclosed in a piston-cylinder arrangement with adiabatic walls. A weight W is added to the piston, resulting in compression of the gas.

Answer:

The answer is the option (a), (b), (d)
(a) During hammering the work done on the rod in hammering converts into heat, raises the temperature of the rod but this heat energy cannot be converted into work, so the process is not reversible.
(b) Heat flows from higher temperature to lower. When the containers are brought in contact, the heat of the bigger one gets transferred to a smaller container until the temperature in both the containers become equal, which is an average of both. But the heat cannot flow from smaller to larger.
(d) Adding weight to the piston increases the pressure and decreases the volume. It cannot be reversed back itself.

Question:8

An ideal gas undergoes isothermal process from some initial state I to final state f. Choose the correct alternatives
a) dU = 0
b) dQ = 0
c) dQ = dU
d) dQ = dW

Answer:

The answer is the option (a) and (d).
Since the process is isothermal \Delta T=0or T is constant
For an ideal gas, dU=Change in internal energy=nCvdT
dT=0 ;Thus dU=0
dQ=dU+dW
dQ=dW
Hence, a and d are correct.

Question:9

Figure shows the P-V diagram of an ideal gas undergoing a change of state from A to B. Four different parts I, II, III and IV as shown in the figure may lead to the same change of state.

(a) Change in internal energy is same in IV and III cases, but not in I and II.
(b) Change in internal energy is same in all the four cases.
(c) Work done is maximum in case I
(d) Work done is minimum in case II.

Answer:

The answer is the option (b) and (c). dU is independent of the path followed in a P-V diagram. It depends only on the initial and final position. Work done is the area enclosed with the V-axis.
The initial and final position is the same for different parts I, II, III, IV. So change in U is same. Hence b is correct.
As area enclosed by the path I is maximum with V-axis, so work done during path I is maximum and minimum in III.
Hence, c is correct.

Question:10

Consider a cycle followed by an engine

1 to 2 is isothermal
2 to 3 is adiabatic
3 to 1 is adiabatic
Such a process does not exist because
a) heat is completely converted to mechanical energy in such a process, which is not possible
b) mechanical energy is completely converted to heat in this process, which is not possible
c) curves representing two adiabatic processes don’t intersect
d) curves representing an adiabatic process and an isothermal process don’t intersect

Answer:

The answer is the option (a) and (c).
The given process is cyclic, which starts at 1 and ends at 1.
So, dU=0
And dQ= dU+dW
dQ=dW
The heat energy supplied to the system gets converted to mechanical work which isn't possible by the second law of thermodynamics.

Question:11

Consider a heat engine as shown on the figure. Q_{1} and Q_{2} are heat added to heat bath T_{1} and heat taken from T_{2} in one cycle of the engine. W is the mechanical work done on the engine.

If W > 0, then possibilities are:
a) Q_{1} > Q_{2} > 0
b) Q_{2} > Q_{1} > 0
c) Q_{2} < Q_{1} < 0
d) Q_{1} < 0, Q_{2} > 0

Answer:

The answer is the option (a) and (c)
Q_{1}=W+Q_{2} (From above figure)
W>0\\ Q_{1}-Q_{2}>0\\ Q_{1}>0
Thus, Q_{1}>0 if both Q_{1} and Q_{2} are positive.
And Q_{1}<Q_{2}<0 if both are negative.
Hence, a and c are correct.

Question:12

Can a system be heated, and its temperature remains constant?

Answer:

A system can be heated, but with a constant temperature when it does work against the surrounding to compensate for the heat supplied.
\Delta T=0 \Rightarrow \Delta U=0
\Delta Q=\Delta U+\Delta W
\Delta Q=\Delta W

Question:13

A system goes from P to Q by two different paths in the P-V diagram as shown in Figure. Heat given to the system in path 1 is 1000 J. The work done by the system along path 1 is more than path 2 by 100 J. What is the heat exchanged by the system in path 2?



Answer:

For path 1 Q1=1000J
WD=W_1-W_2=100
W_1=WD through path 1
W_2=WD through path 2
W_{2}=W_{1}-100 (Change in internal energy by both paths are same)
\Delta U=Q_{1}-W_{1}=Q_{2}-W_{2}\\ 1000-W_{1}=Q_{2}-(W_1-100)
Q_2=900J

Question:14

If a refrigerator’s door is kept open, will the room become cool or hot? Explain.

Answer:

When the refrigerator door is kept open, the amount of heat absorbed from inside the refrigerator and the work is done on it by electricity both will be rejected by the refrigerator in the room. This will make the room hotter.

Question:15

Is it possible to increase the temperature of a gas without adding heat to it? Explain.

Answer:

In adiabatic compression, the temperature of gas increases while no heat is added to the system.
dQ=0
dQ=dU+dW
dU=-dW
So in compression work done on the system is negative. Thus, dU is positive, increasing the temperature of the system. As the internal energy of gas increases, its temperature decreases.

Question:16

Air pressure in a car tyre increases during driving. Explain.

Answer:

During driving, a reaction force is applied due to the force on tyres. The temperature of gas increases due to this reaction force causing the gas inside the tyre to expand while the volume inside the tyre remains constant. In accordance with the Charles Law, the temperature of the car tyre increases as well as the pressure (P\propto T)

Question:17

Consider a Carnot’s cycle operating between T_1 = 500K and T_{2} = 300K producing 1 k J of mechanical work per cycle. Find the heat transferred to the engine by the reservoirs.

Answer:

The efficiency of Carnot's engine \mu =1-T_2/T_1
T_{1}(Temp of source)=500K
T_{2}Temp of sink=300K
\frac{\text{Output work}}{\text{Input work}}=1-\frac{300}{500 }
\frac{1000 J}{x}=1-0.6
\frac{1000 }{x}=0.4
x=\frac{1000}{0.4}=2500J

Question:18

A person of mass 60 kg wants to lose 5kg by going up and down a 10m high stairs. Assume he burns twice as much fat while going up than coming down. If 1 kg of fat is burnt on expending 7000 kilo calories, how many times must he go up and down to reduce his weight by 5 kg?

Answer:

The energy produced by 1 kg fat=7000 k cal
Energy produced by 5 kg fat=35000 k cal=35×106 cal
Energy consumed to go up one time=mgh
Energy consumed to go up and down one time=mgh+0.5mgh
E=\frac{3}{2}mgh=\frac{3}{2}\times 60\times 10\times 10=9000 J=\frac{9000}{4.2}cal
Let us assume that he goes up and down n times, then
n\times \frac{9000}{4.2}=35\times 10^{6}
n=35\times 10^{6}\times \frac{4.2}{9000}=16.3\times10^3

Question:19

Consider a cycle tyre being filled with air by a pump. Let V be the volume of the tyre (fixed) and at each stroke of the pump \Delta V\leq V)
of air is transferred to the tube adiabatically. What is the work done when the pressure in the tube is increased from P1 to P2?

Answer:

Air is transferred into tyre adiabatically.
Let the initial volume of air be V and after pumping it becomes V+dV and pressure P+dP
P_1 V_1^\gamma =P_2V_{2}^{\gamma }
P(V+dV)^\gamma =(P+dP)V^\gamma
PV^\gamma \left [1+\frac{dV}{V} \right ]^\gamma =P\left [1+\frac{dP}{P} \right ]V^\gamma
PV^\gamma \left [1+\gamma \frac{dV}{V} \right ]=PV^\gamma\left [ 1+\frac{dP}{P} \right ]
On expanding by binomial theorem and neglecting the higher terms
1+\gamma \frac{dV}{V}=1+\frac{dP}{P}
dV=\frac{VdP}{\gamma P}
\int pdV=\int_{P_{1}}^{P_{2}}\frac{VdP}{\gamma }
\int_{W_{1}}^{W_{2}}dW=\frac{V}{\gamma }(P_2-P_1)
W=\frac{V}{\gamma }\left (P_2-P_1 \right )

Question:20

In a refrigerator, one removes heat from a lower temperature and deposits to the surroundings at a higher temperature. In this process, mechanical work has to be done, which is provided by an electric motor. If the motor is of 1kW power, and heat is transferred from to , find the heat taken out of the refrigerator per second assuming its efficiency is 50% of a perfect engine.

Answer:

Here refrigerator acts as a Carnot's engine in reverse order with an efficiency \eta

\eta =1-\frac{T_2}{T_1}=1-\frac{270}{300}=110

\eta '=0.5\times0.1=0.05
Coefficient of performance \beta =\frac{Q_2}{W}=\frac{1-\eta '}{\eta '}=\frac{1-0.05}{0.05}=19
Q2=19% WD by motor on Refrigerator
=19\times 1kW=19kJs

Question:21

If the coefficient of performance of a refrigerator is 5 and operates at the room temperature, find the temperature inside the refrigerator.

Answer:

\beta=\frac{T_2}{T_1-T_2}
T_1=27+273=300K
5=\frac{T_{2}}{300-T_{2}}
On solving, we get
T_2=250K

Question:22

The initial state of a certain gas is P_i, V_i, T_i. It undergoes expansion till its volume becomes V_f. Consider the following two cases:
a) the expansion takes place at constant temperature
b) the expansion takes place at constant pressure
Plot the P-V diagram for each case. In which of the two cases, is the work done by the gas more?

Answer:

The expansion from Vi to Vf at a constant temperature in (a) is an isothermal expansion.i.e.
P_{i}V_{i}=P_fV_f at a constant temp.
The expansion at constant pressure in (b) is the isobaric process wherein the graph of P-V will be parallel to V axis until its volume becomes V_f.
The area enclosed by graph (a) is less than the graph (b). So, work done by the process (b) is more than (a).

a) find the work done when the gas is taken from state 1 to state 2
b) what is the ratio of temperature \frac{T_{1}}{T_{2}} if V_{2}=2V_{1}
c) given the internal energy for one mole of gas at temperature T is \left (\frac{3}{2} \right )RT, find the heat supplied to the gas when it is taken from state 1 to 2 with V_2 = 2V_1.

Answer:

Let P_{1}V_{1}^{\frac{1}{2}}=P_BV_B^{\frac{1}{2}}=K
And P=\frac{K}{V^{\frac{1}{2}}}
Work done for process 1 to 2; WD=\int_{V_{1}}^{V_{2}}PdV=\int_{V_{1}}^{V_{2}}\frac{K}{V^{\frac{1}{2}}}dV=K\left [ \frac{V^{\frac{1}{2}}}{\frac{1}{2}} \right ]=2K\left [ \sqrt{V_{2}}-\sqrt{V_{1}} \right ]
WD from V1to V2=
dW=2P_1V_1^{\frac{1}{2}}V_2-V_1=2P_2V_2^{\frac{1}{2}}V_2-V_1
  1. Equation of ideal gas PV=nRT
T=\frac{PV}{nR}=\frac{K\sqrt{V}}{nR }
T_{1}=\frac{K\sqrt{V_{1}}}{nR }and T_{2}=\frac{K\sqrt{V_{2}}}{nR }
\frac{T_1}{T_2}=\frac{\sqrt{V_1}}{\sqrt{V_2}}=\frac{1}{\sqrt{2}}
(c )
\Delta U=\frac{3}{2}R\Delta T=\frac{3}{2}R(T_{2}-T_{1})
\Delta U=\frac{3}{2}RT_1(\sqrt{2}-1)
dW=2P_1V_1\frac{1}{2}\left (\sqrt{V_2}-\sqrt{V_1} \right )
dW=2P_1V_1^{\frac{1}{2}}(\sqrt{2V_1}-\sqrt{V_1})
dW=2P_1V_1(\sqrt{2}-1) =2nRT_{1}(\sqrt{2}-1)
n=1
dW=2RT_1(\sqrt{2}-1)
dQ=dW+dU=2RT_{1}(\sqrt{2}-1)+\frac{3}{2}RT_{1}\left (\sqrt{2}-1 \right )
=(\sqrt{2}-1)RT_{1}\left (2+\frac{3}{2} \right )

Question:24

A cycle followed by an engine is shown in the figure.

A to B: volume constant
B to C: adiabatic
C to D: volume constant
D to A: adiabatic
V_C = V_D = 2V_A = 2V_B
a) in which part of the cycle heat is supplied to the engine from outside?
b) in which part of the cycle heat is being given to the surrounding by the engine?
c) what is the work done by the engine in one cycle in terms of P_A, P_B, V_A?
d) what is the efficiency of the engine?

Answer:

(a) Heat is supplied to the engine in part AB where dV=0
dW=PdV=P(0)
dW=0
dQ=dU+dW(First law of thermodynamics)
dQ=dU
P=\frac{nRT}{V}
V=constant
p\propto T
(b) Heat is given out by the system in a part CD where dV=0 and pressure and temperature decreases
(c ) WD by system=\int_{B}^{A}PdV+\int_{B}^{C}PdV+\int_{C}^D{}PdV+\int_{D}^{A}PdV
\int_{B}^{A}PdV=0 \text{and}\int_{C}^D{}PdV=0
For adiabatic change
PV^{\gamma}=K
P=\frac{K}{V^{\gamma}}

\int_{B}^{C}PdV=\int_{A}^{B}\frac{K}{V^{\gamma }}dV=K\left [ \frac{V^{-\gamma +1}}{1-\gamma } \right ]^{V_{C}}_{V_{B}}
\int_{B}^{C}PdV=\frac{K}{1-\gamma}\left [ V_{C}^{1-\gamma}-V_{B}^{1-\gamma} \right ]
\int_{D}^{A}PdV=\frac{K}{1-\gamma}\left [ V_{A}^{1-\gamma}-V_{D}^{1-\gamma} \right ]
\int_{D}^{A}PdV=\frac{P_{A}V_{A}^{\gamma}V_{A}^{1-\gamma}-P_{D}V_{D}^{\gamma}V_{D}^{1-\gamma}}{1-\gamma}
\int_{D}^{A}PdV=\frac{P_{A}V_{A}-P_{D}V_{D}}{1-\gamma}
\int_{D}^{A}PdV=\frac{P_{A}V_{A}-P_{D}V_{D}}{1-\gamma}
\int_{B}^{C}PdV=\frac{P_{C}V_{C}-P_{B}V_{B}}{1-\gamma}
Total WD=\frac{[P_{C}V_{C}-P_{B}V_{B}+P_{A}V_{A}-P_{D}V_{D}]}{1-\gamma}
For Adiabatic change=P_{B}V_{B}^\gamma =P_{C}V_{C}^{\gamma}
P_C=\frac{P_BV_B^{\gamma}}{V_C^\gamma}=P_B\left (\frac{V_B}{V_C} \right )^\gamma=P_B\left (\frac{V_B}{2V_B} \right )^\gamma=\frac{P_B}{2^\gamma}
P_{D}=\frac{P_{A}}{2^\gamma }
Net WD= \frac{1}{1-\gamma} [P_BV_C2-\gamma-P_BV_B+P_AV_A-P_AV_D2-\gamma ]
=\frac{1}{1-\gamma}[P_B2V_B2^{-\gamma}-P_BV_B+P_AV_A-P_A2V_A2^{-\gamma}]
=\frac{1}{1-\gamma}[-P_{B}V_{B}[-2^{1-\gamma }+1]P_{A}V_{A}[-2^{1-\gamma }+1]]
=\frac{1}{1-\gamma}[P_{A}V_{A}-P_{B}V_{B}][1-2^{1-\gamma}]
2V_B=2V_A\Rightarrow V_B=V_A=\frac{1}{1-\frac{5}{3}}\left [ -2^{1-\frac{5}{3}}+1 \right ][-P_B+P_A]V_A
=\frac{3}{2}\left [ 1-\left ( \frac{1}{2} \right )^{\frac{2}{3}} \right ][P_B-P_A]V_A

Question:25

A cycle followed by an engine is shown in the figure. Find heat exchanged by the engine, with the surroundings for each section of the cycle considering C_{v} = \left (\frac{3}{2} \right )R.

AB: constant volume
BC: constant pressure
CD: adiabatic
DA: constant pressure

Answer:

Ans.

(a) For A\rightarrow B, dV=0
dW=\int PdV=\int P\times 0=0
dQ=dU+dW=dU+0
dQ=dU
dQ=nC_vdT
n=1;C_v=\frac{3}{2}R
dQ=1\left (\frac{3}{2} R \right )(T_B-T_A)
dU=dQ_1=\frac{3}{2}\left (RT_B-RT_A \right )=\frac{3}{2}(P_BV_B-P_AV_A)
(b) B\rightarrow C
dQ_2=dU+dW=C_vdT+P_BdV
dQ_2=\frac{3}{2}R\left (T_C-T_B \right )+P_B\left (V_C-V_B \right )
=\frac{3}{2}[P_CV_C]-\frac{3}{2}{P_BV_B}-P_BV_B+P_BV_C
V_A=V_B and P_B=P_{C}
dQ_2=\frac{5}{2}P_BV_C-\frac{5}{2}P_BV_A=\frac{5}{2}P_B[V_C-V_A ]
(c ) C\rightarrow D, adiabatic change
dQ_{3}=0
  1. In diagram D\rightarrow A
\Delta P=0
Compression of gas at constant pressure takes place. Therefore, heat exchange is similar to part (b)
dQ_{4}=\frac{5}{2}P_A(V_A-V_D)

Question:26

Consider that an ideal gas is expanding in a process given by P = f(V), which passes through a point (V_0, P_0). Show that the gas is absorbing heat at (P_0, V_0) if the slope of the curve P = f(V) is larger than the slope of the adiabat passing through (P_0, V_0).

Answer:

Slope of graph at
(V_0,P_0)=\frac{dP}{dV}_{(P_0,V_0)}
P=f(V) for adiabatic process PV^{\gamma }=\text{constant }K
P=\frac{K}{V^{\gamma}}
\frac{dP}{dV}=-\frac{\gamma P}{}V
(\frac{dP}{dV})_{(P_0,V_0)}=-\gamma \frac{P_0}{V_0 }
P=f(V)
dQ=dU+dW
dQ=nC_vdT+PdV
PV=nRT
T=\frac{PV}{nR}=\frac{V}{nR}f(V)
\frac{dT}{dV}=\frac{1}{nR}[f(V)+Vf'(V)]
\frac{dQ}{dV}=nC_v\left (\frac{dT}{dV} \right )+P\left (\frac{dV}{dV} \right )=\frac{nC_v}{nR}[f(V)+V(f'(V))+P]
\frac{dQ}{dV}_{(V=V_0)}=\frac{C_v}{}R\left [f(V_0)+V_0(f'(V_0))+f(V_0) \right ]
=f(V_0)\left [\frac{C_v}{}R+1 \right ]+V_0f'(V_0)\frac{C_v}{}R
C_P-C_v=R\Rightarrow \frac{C_P}{C_V}-1=\frac{R}{C_v}
\gamma -1=\frac{R}{C_v}\Rightarrow C_v=\frac{R}{\gamma -1}\Rightarrow \frac{C_v}{}R=\frac{1}{\gamma -1}
\frac{dQ}{dV}_{(V=V_0)}=\frac{1}{r-1}\left [\gamma P_0+V_0f'{(V_0)} \right ]
\frac{dQ}{dV}_{(V=V_0)}>1 and \gamma >1 so\frac{1}{\gamma -1}>0
\gamma P_0+V_0f'(V_0)>0
V_0f'(V_0)>-\gamma P_0
f'V_0>-\frac{\gamma P_0}{V_0}

Question:27

Consider one mole of perfect gas in a cylinder of unit cross-section with a piston attached. A spring is attached to the piston and to the bottom of the cylinder. Initially the spring is unstretched and the gas is in equilibrium. A certain amount of heat Q is supplied to the gas causing an increase of volume from V0 to V1.

a) what is the initial pressure of the system?
b) what is the final pressure of the system?
c) using the first law of thermodynamics, write down the relation between Q, Pa, V, V0, and k.

Answer:


  1. Piston is considered massless and balanced by atmospheric pressure. So the initial
pressure of system inside cylinder is Pa
  1. On supplying heat volume of gas increases from V_{0}to V_1

Increase in Volume=V_1-V_{0} =Area of base×height=A\times x
V_{1}-V_{0}=A\times x
x=\frac{V_{1}-V_{0}}{A}
(Force exerted by spring)
F=Kx=\frac{K(V_1-V_0)}{A}
(Force due to spring on unit area)
F=K(V_{1}-V_0)
(Final total pressure on gas)
P_f=P_a+K(V_1-V_0)
  1. dQ=dU+dW (First law of thermodynamics)
dU=C_v(T-T_0)
T=final temperature of the gas
T0=initial temperature of the gas
n=1
T_y=T=\frac{P_fV_f}{R}=\frac{\left [P_a+K(V_1-V_0) \right ]}{R}
dW=P_a(V_1-V_0)+\frac{1}{2}kx^{2}(Increase in potential energy of spring)
dQ=dU+dW=C_v(T-T_0)+P_a(V_1-V_0)+\frac{1}{2}kx^2
dQ=dU+dW=C_v(T-T_0)+P_a(V_1-V_0)+\frac{1}{2}k(V_1-V_0)^2.
