Question

Consider two processes on a system as shown in figure. The volumes in the initial states are the same in the two processes and the volumes in the final states are also the same. Let $\Delta W_1$ and $\Delta W_2$ be the work done by the system in the processes $A$ and $B$ respectively.

Professor PC Thomas Classes · Answer

Both are isobaric expansions. In A, the pressure is lower and $\Delta V_1<\Delta V_2$. This can be concluded from Charle's Law of constant pressure.
