In a process on a system, the initial pressure and volume are equal to the final pressure and volume.

Options

A. The initial energy must be equal to the final internal energy
B. The net heat given to the system in the process must be zero
C. The net work done by the system in the process must be zero
D. The initial temperature must be equal to the final temperature

Answer

A, D

Explanation

When `P and `V` remain unchanged, temperature must also remain unchanged and so must be the internal energy of the system.
