Question: Work Done in a Cyclic Process (a) In Fig. 19.7a, consider the closed loop 1 3 + 2 4 1. This is a cyclic process

Work Done in a Cyclic Process
(a) In Fig. 19.7a, consider the closed loop 1 → 3 →+ 2 → 4 → 1. This is a cyclic process in which the initial and final states are the same. Find the total work done by the system in this cyclic process, and show that it is equal to the area enclosed by the loop.
(b) How is the work done for the process in part (a) related to the work done if the loop is traversed in the opposite direction, 1 → 4 → 2 → 3 → 1 Explain.
