Text Solution

Verified by Experts

The correct Answer is:
B
Although neither heat not work is a state function their sum `(q + w)` is equal to `Delta U` and `U` is a state function their sum `(q + w)` is equal to `Delta U` and `U` is a state function Similarly, `q_(v)` is a state function as it is equal to `Delta U`. Moreover by specifying the exact path, we give the path function an exact value.
