Question 14

The pressure of the gas inside a rigid, sealed container decreases when it is placed in a freezer. This is caused by a change in the average speed of the gas particles and a change in the temperature of the gas inside the container.

Which of the following describes the changes associated with this decrease in gas pressure?

A

Average speed of the gas particles decreases; Temperature of the gas decreases

B

Average speed of the gas particles decreases; Temperature of the gas increases

C

Average speed of the gas particles increases; Temperature of the gas decreases

D

Average speed of the gas particles increases; Temperature of the gas increases
