Question

An ideal gas in a closed container is slowly heated. As its temperature increases, which of the following statements are true?\ (A) The mean free path of the molecules decreases.\ (B) The mean collision time between the molecules decreases.\ (C) The mean free path remains unchanged.\ (D) The mean collision time remains unchanged.\

Professor PC Thomas Classes · Answer

(a) : As temperature increases velocity of molecules will increase. So, the mean collision time between molecules will decrease. For a constant volume, mean free path is independent of temperature.\
