Question

the temperature of a gas is increased. which statement best explains the effect that this has on the motion of gas particles? the average kinetic energy decreases, and the particles stop colliding. the average kinetic energy increases, and the particles stop colliding. the average kinetic energy decreases, and the particles collide less frequently. the average kinetic energy increases, and the particles collide more frequently.

Explanation:

According to kinetic - molecular theory, temperature is directly related to the average kinetic energy of gas particles. When temperature increases, kinetic energy rises, and particles move faster, colliding more often.

Answer:

The average kinetic energy increases, and the particles collide more frequently.
