Refer to figure in previous question, `DeltaU_(1)` and `DeltaU_(2)` be the changes in internal energy of the system in the processes `A` and `B` then

Text Solution

Verified by Experts

The correct Answer is:
When the system is taken from the state `A` to `B` the change in internal energy is independent of the path followed. Therefore, `DeltaU_(1) = DeltaU_(2)`
