Question 21 • Chemistry A.1 - F26 - Jacob Metsker

The temperature of a gas is increased. Which statement best explains the effect that this has on the motion of gas particles?

Answer
A
The average kinetic energy decreases, and the particles stop colliding.
B
The average kinetic energy increases, and the particles stop colliding.
C
The average kinetic energy decreases, and the particles collide less frequently.
D
The average kinetic energy increases, and the particles collide more frequently.

Explanation

Temperature measures the particles’ average kinetic energy, so increasing the gas temperature increases their average kinetic energy. The particles move faster and, in the same space, collide more frequently. Therefore, the best choice is “The average kinetic energy increases, and the particles collide more frequently.”
