Question

How will the behavior of the gases in the piston chamber change if more pressure is applied to the piston?

Answer 1

The answer is D.

The gas particles will hit the walls more frequently. Because more pressure is applied, the container will shrink in size. When this happens, the particles have less space to move and will hit the walls of the container more frequently, exerting more pressure.

Answer 2

Here molecules of gas remains constant. If more pressure is applied to the piston, gaseous molecules will come closer to each other. Hence their volume decreases and density increases. Hope this helps you.
