검증된 단계별 안내1
Recall the kinetic molecular theory, which explains the behavior of gas particles in terms of their motion and energy.
Understand that temperature is a measure of the average kinetic energy of the particles in a substance.
Recognize that as temperature increases, the average kinetic energy of gas particles also increases.
Know that an increase in kinetic energy means the particles move faster because kinetic energy is directly related to the velocity of the particles.
Conclude that with higher temperature, gas particles move faster and their average kinetic energy increases, which matches the correct answer.
