In which of the following process (es), there is no change in the internal energy of the system?

A

Isothermal

B

Adiabatic

C

Free expansion

D

Cyclic

Text Solution

Verified by Experts

The correct Answer is:
A, C, D
In isothermal process, heat supplied is used to do work against external surroundings, in free expansion as `P=0`, so change in internal energy is zero, and cyclic process, system is returened to its initial state `:. DeltaU=0`
