List the factors affecting the mean free path.

Explanation

(i) Mean free path `square` is directly proportional to the mass of the gas molecule. `square propm`
(ii) `squareprop(1)/(rho),rho` - density of the gas
(iii) `squareprop(1)/(d^(2)),d`- molecular diameter.
(iv) `squarepropT,T`- absolute temperature of the gas
(v) `squareprop(1)/(P),P` - pressure of the gas.
