Question 33

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

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

A

The average kinetic energy decreases and the pressure decreases.

B

The average kinetic energy stays the same and the pressure decreases.

C

The average kinetic energy decreases and the pressure increases.

D

The average kinetic energy increases and the pressure decreases.
