Question 30 POST_UTME_UNIOSUN • 2025 • PHYSICS • objective

A gas is confined to a cylinder of volume $V$ with a movable piston. If the temperature of the gas is $T$ and the pressure is $P$, what is the work $W$ done by the gas?

Correct Answer A. The work $W$ done by the gas is equal to the pressure $P$ times the change in volume $\Delta V$.

B. The work $W$ done by the gas is equal to the pressure $P$ divided by the change in volume $\Delta V$.

C. The work $W$ done by the gas is equal to the pressure $P$ minus the change in volume $\Delta V$.

D. The work $W$ done by the gas is equal to the pressure $P$ plus the change in volume $\Delta V$.

Correct Answer

Correct Option:

The work $W$ done by the gas is equal to the pressure $P$ times the change in volume $\Delta V$.
