Question

The kinetic molecular theory of gases predicts pressure to rise as the temperature of a gas increases. It is because

A. gas molecules collide more frequently with the container walls
B. gas molecules collide less frequently with the container walls
C. gas molecules have less kinetic energy
D. gas molecules collide less energetically with container walls

Answer 1

According to the Kinetic Molecular Theory, pressure in a gas increases with temperature because gas molecules collide more frequently and with greater force against the container walls, resulting in higher pressure.

Step-by-step explanation:

The Kinetic Molecular Theory of gases predicts that the pressure of a gas increases as the temperature increases because gas molecules collide more frequently and energetically with the container walls. This is due to an increase in the average speed and kinetic energy of the molecules, which, when the volume is held constant, leads to more frequent and forceful collisions with the walls, thus increasing pressure as stated by Amontons's law. With higher kinetic energy, the molecules exert greater force during each collision, contributing to the rise in pressure.
