Graham's law of Diffusion or Effusion | video in HINDI

In this Physics ( Thermodynamics ) video tutorial in Hindi / Urdu for class 11 and B.Sc. Part 1 we discussed on Graham's law of Diffusion or Effusion and explained the mathematical derivation of the formula from the Kinetic Theory of gases. Graham's law states that the rate of diffusion or of effusion of a gas is inversely proportional to the square root of its molecular weight.
In the same conditions of temperature and pressure, the molar mass is proportional to the mass density. Therefore the rate of diffusion / effusion of different gases is inversely proportional to the square root of their densities.
