Question 70

A gas in a sealed, rigid container of fixed volume is cooled, so that its particles lose thermal energy.

Which effect does this have on the gas?

A

Both the pressure of the gas and the average kinetic energy of its particles decrease.

B

Only the average kinetic energy of the particles decreases.

C

Neither the pressure nor the average kinetic energy of the particles decreases.

D

Only the pressure of the gas decreases.
