Q. A system changes from state $X$ to $Y$ with a change in internal energy measuring to 25 $kJ \, mol^{- 1}$ , by a reversible path and returns from $Y $ to $X$ by an irreversible path. What will be the net change in internal energy?

Solution:

For a cyclic process, net change in internal energy is zero. Change in internal energy does not depend on the path by which final stage is reached.
