$A$ system goes from $A$ to $B$ via two processes $I$ and $II$ as shown in the figure. If $\Delta U_I$ and $\Delta U_{II}$ are the changes in internal energies in the processes $I$ and $II$ respectively,then:
- A$\Delta U_{II} > \Delta U_I$
- B$\Delta U_{II} < \Delta U_I$
- C$\Delta U_I = \Delta U_{II}$
- DThe relation between $\Delta U_I$ and $\Delta U_{II}$ cannot be determined.
