The mean free path of collision of gas melecules varies with its diameter (d) of the molecules as

The mean free path of a gas molecule is the distance

The mean free path of a gas molecule is the distance

Mean free path of a molecule is

Mean free path of a molecule 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.
