The kinetic- molecular theory predicts that pressure rises as the temperature of a gas increases because _ .
A) the gas molecules collide less frequently with the wall
B) the gas molecules collide more frequently with the wall
C) the average kinetic energy of the gas molecules decreases
D) the gas molecules collide more energetically with the wall
E) both the gas molecules collide more frequently with the wall and the gas molecules collide more energetically with the wall

Question

Quizplus · Accepted Answer

As temperature increases, the average kinetic energy of gas molecules increases, leading to more frequent and more energetic collisions with the walls, thus increasing pressure.
