$\Delta U = 0$ in all three cases.

Vedclass · Answer

(D) Internal energy $(U)$ is a state function,meaning its value depends only on the initial and final states of the system,not on the path taken.For a cyclic process,the system returns to its initial state after completing the cycle.Since the initial state and final state are identical,the change in internal energy $(\Delta U)$ for any cyclic process is always zero.All three figures $(a)$,$(b)$,and $(c)$ represent cyclic processes because the path starts and ends at the same point.Therefore,$\Delta U = 0$ for all three cases.

What is the nature of the change in internal energy for the following three thermodynamic processes shown in the figure?
