A gas is contained in the piston assembly and allowed to expand as in the following figure.Which point on the graph shows the correct final pressure and volume?

Question

Quizplus · Accepted Answer

Since the gas is allowed to expand, the volume will increase and the pressure will decrease. Therefore, the final point should be towards the right and lower on the graph. Point C is the only one that satisfies these conditions, so it is the correct final pressure and volume.
