Question 7

A sealed, rigid metal container contains a gas. The gas and container are initially at room temperature. The gas and container are then heated.

Which row in the table describes the change in the average kinetic energy of the gas molecules and the pressure of the gas as the temperature increases?

Average kinetic energy of the gas moleculesPressure of the gas
Aincreasesincreases
Bincreasesstays the same
Cdecreasesdecreases
Dstays the sameincreases
A

Average kinetic energy increases; pressure increases

B

Average kinetic energy increases; pressure stays the same

C

Average kinetic energy decreases; pressure decreases

D

Average kinetic energy stays the same; pressure increases
