The mean free path is the average distance traveled by a particle between collisions with other particles. Calculate the mean free path of air at room temperature, =69.8 ∘F. Air is mostly nitrogen, so assume that the collisions are between moving N2 molecules. The diameter of N2 is =1.58×10−10 m and the gas is at atmospheric pressure, =101325 Pa
