Vedclass · Answer

(A) The mean free path $(\lambda)$ is given by the formula $\lambda = \frac{k_B T}{\sqrt{2} \pi d^2 P}$,where $P$ is the pressure.As the pressure $(P)$ increases,the volume decreases and the density of gas molecules increases.This causes the molecules to come closer to each other,resulting in more frequent collisions.Therefore,the mean free path decreases as pressure increases.
