An ideal gas is kept in a rigid container.When its temperature is 100 K,the mean-free-path of the gas molecules is λ.What will be the mean-free-path of the molecules at 400 K?
A) 4λ
B) 2λ
C) λ
D) λ/2
E) λ/4

Question

Quizplus · Accepted Answer

The mean free path (λ) of gas molecules in a rigid container is independent of temperature because it primarily depends on the density and diameter of the molecules, both of which remain constant in a rigid container. Therefore, changing the temperature does not affect λ.
