The internal energy change when a system goes from state A to B is 40 kJ/mole. If the system goes from A to B by a reversible path and returns to state A by an irreversible path what would be the net change in internal energy?

Ans)
For a cyclic process the net change in internal energy is ZERO(0).

For a cyclic process the net change in the internal energy is zero because the change in internal energy does not depend on the path.
