On a PV diagram,if a process involves a closed curve,the area inside the curve represents
A)internal energy.
B)heat.
C)work.
D)zero.

Question

Quizplus · Accepted Answer

A closed curve on a PV diagram represents a cycle or a closed loop process. The area enclosed by the curve represents the net work done by the system during the cycle. This is because the work done during the forward path of the cycle is positive, while the work done during the reverse path is negative. The net work done is equal to the difference between the two, which is represented by the area enclosed by the cycle. Therefore, option C) work is the correct choice. Options A) internal energy and B) heat are not represented by the area enclosed by the curve on a PV diagram. Option D) zero is incorrect because the area inside the closed curve has a definite value representing the net work done by the system.
