When a system goes from state $A$ to state $B$,the change in internal energy is $40 \, kJ/mol$. If the system returns from state $B$ to state $A$ via a reversible path and then returns to state $A$ via an irreversible path,what is the net change in internal energy?
- A$< 40 \, kJ$
- BZero
- C$40 \, kJ$
- D$> 40 \, kJ$
