B)Its pressure would increase.
C)Its pressure would hold constant.
D)The number of moles of the gas would decrease.
E)The average kinetic energy of the molecules of the gas would decrease.

Question

Quizplus · Accepted Answer

According to the kinetic molecular theory of gases, an increase in temperature increases the average kinetic energy of the gas molecules, which in turn increases the frequency and force of collisions between molecules and with the walls of the container. This increased collision frequency and force will cause an increase in pressure. Additionally, a decrease in volume will cause the gas molecules to be more closely packed and collide more frequently, thereby further increasing the pressure. Therefore, as both temperature and volume decrease, the pressure of the gas will increase.
