Vedclass · Answer

(A) Internal energy $(U)$ is a state function. State functions depend only on the initial and final states of the system and are independent of the path taken to reach the final state. In both processes $I$ and $II$,the system starts at state $A$ and ends at state $B$. Therefore,the change in internal energy for both processes is the same: $\Delta U_1 = U_B - U_A$ and $\Delta U_2 = U_B - U_A$. Hence,$\Delta U_1 = \Delta U_2$.

$A$ system goes from $A$ to $B$ via two processes $I$ and $II$ as shown in the figure. If $\Delta U_1$ and $\Delta U_2$ are the changes in internal energies in the processes $I$ and $II$ respectively,then:
