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

A

$\Delta U_1 = \Delta U_2$

B

relation between $\Delta U_1$ and $\Delta U_2$ cannot be determined

C

$\Delta {U_2} > \Delta {U_1}$

D

$\Delta {U_2} < \Delta {U_1}$

Solution

The intemal energy is a function of thermodynamic state only and does not depend on the path. Hence

$\Delta \mathrm{U}_{1}=\Delta \mathrm{U}_{2}$
