Question 90

The temperature of a gas in a sealed container of fixed volume is reduced, causing the gas particles to lose energy from their kinetic store. Which of the following describes the effects of this change on the gas?

A

Both the pressure of the gas and the average speed of its particles decrease.

B

Only the pressure of the gas decreases, while the average speed of its particles remains constant.

C

Only the average speed of its particles decreases, while the pressure of the gas remains constant.

D

Neither the pressure of the gas nor the average speed of its particles decreases.
