Meen Free Path

Calculation OF Work from Graphs

SI unit of mean free path is

Statement-1 : Mean free path of molecules of a gas decreases with increases in number density of the molecules. Statement-2 : More the molecules per unit volume, more are the chances of molecular collision. Therefore, mean free path decreases.

A molecule of a gas, filled in a discharge tube, gets ionized when an electron is detached from it. An electric field of 5.0 kV m^(-1) exists in the vicinity of the event. (a) Find the distance travelled by the free electron in 1 mus assuming no collision. (b) If the mean free path of the electron is 1.0 mm , estimate the time of transit of the free electron between successive collisions.

Calculate what fraction of gas molecules (a) traverses without collisions the distances exceeding the mean free path lamda , (b) has the free path values lying within the inerval from lamda to 2 lamda .
