Question 59

A fixed mass of gas is trapped in a rigid container. The temperature of the gas is decreased while the volume of the gas is kept constant. How does this change affect the average kinetic energy of the molecules and the pressure exerted on the walls of the container?

A

Average kinetic energy decreases, pressure decreases

B

Average kinetic energy stays the same, pressure decreases

C

Average kinetic energy decreases, pressure increases

D

Average kinetic energy stays the same, pressure increases
