A system goes from $A$ to $B$ via two processes I and II as shown in figure. If $\Delta U_{1}$ and $\Delta U_{2}$ are the changes in internal energies in the processes I and II respectively, then the relation between $\Delta U_{1}$ and $\Delta U_{2}$ is
$\Delta U_{1}=\Delta U_{2}$
$\Delta U_{2} < \Delta U_{1}$
$\Delta U_{2}>\Delta U_{1}$
can not be determined
Solution
Change in internal energy do not depend upon the path followed by the process. It only depends on initial and final states i.e., $\Delta U_{1}=\Delta U_{2}$
