D | Isobaric Process |
Choose the correct answer from the options given below: |
A
A-I, B-II, C-IV, D-III
B
A-II, B-I, C-IV, D-III
C
A-I, B-II, C-III, D-IV
D
A-II, B-I, C-III, D-IV
Answer
A-II, B-I, C-IV, D-III
Explanation
Solution
The correct answer is (B) : A-II, B-I, C-IV, D-III
ΔU=nCvΔT
For isothermal process T is constant
So ΔU=0
A⟶II
Adiabatic process
ΔQ=0
ΔQ=ΔU+ΔW
ΔU=−ΔW
Work done by gas is positive
So ΔU is negative
B ⟶ I
For Isochoric process ΔW=0
C⟶IV
For Isobaric process
ΔW=PΔV=0
ΔU=nCVΔT=0
Heat absorbed goes partly to increase internal energy and partly do work.
