A system goes from $A$ to $B$ via two processes I and II as shown in the figure. If $\Delta \mathrm{U}_1$ and $\Delta \mathrm{U}_2$ are the changes in internal energies in the processes I and II respectively, the
  1. $\Delta \mathrm{U}_1=\Delta \mathrm{U}_2$
  2. relation between $\Delta \mathrm{U}_1$ and $\Delta \mathrm{U}_2$ can not be determined
  3. $\Delta \mathrm{U}_2>\Delta \mathrm{U}_1$
  4. $\Delta \mathrm{U}_2 < \Delta \mathrm{U}_1$

Solution

Internal energy is state function
