Question 31

A fixed mass of gas is trapped in a cylinder with a movable piston.

The volume of the gas is decreased, but the temperature of the gas is kept constant.

How does this change affect the average kinetic energy of the molecules and the pressure of the gas on the walls of the cylinder?

A

Average kinetic energy stays the same; pressure increases

B

Average kinetic energy increases; pressure increases

C

Average kinetic energy stays the same; pressure decreases

D

Average kinetic energy decreases; pressure stays the same
