Text Solution

Verified by Experts
The correct answer is:
B

For isothermal process T is constant

So

A II Adiabatic process

Q = 0

Q = U + W

U=- W

Work done by gas is positive

So U is negative B I

For Isochoric process W = 0

C V

For Isobaric process

W = P Y 0

U = nCv

Heat absorbed goes partly to increase internal energy and partly do work.
