A certain amount of a monatomic gas is maintained at constant volume as it is cooled by 50 K. This feat is accomplished by removing 400 J of energy from the gas. How much work is done by the gas?

Question

Quizplus · Accepted Answer

When a gas is maintained at constant volume and cooled, the volume does not change, meaning no work is done by the gas. Work done by a gas is given by the formula W = PΔV, where P is pressure and ΔV is the change in volume. Since the volume does not change (ΔV = 0), the work done (W) is zero.
