Question 41

A fixed mass of gas is trapped in a container. The volume of the container is decreased while the temperature of the gas is kept constant.

How does this change affect the average kinetic energy of the gas molecules and the rate of collisions of the gas molecules with the walls of the container?

A

Average kinetic energy stays the same; rate of collisions increases

B

Average kinetic energy increases; rate of collisions increases

C

Average kinetic energy stays the same; rate of collisions decreases

D

Average kinetic energy decreases; rate of collisions stays the same
