Of the following which might NOT vanish over one cycle of a cyclic process?

Question

Quizplus · Accepted Answer

In a cyclic process, the net work done by the system is equal to the net heat absorbed, so option A vanishes. Changes in state variables like pressure, volume, and temperature (options B, D, and E) return to their initial values, so they vanish. However, the energy absorbed as heat (option C) does not necessarily vanish, as it can be converted to work or stored.
