When a gas is allowed to escape through a fine pin hole the phenomenon is termed as effusion.

DIFFUSION:-

Diffusion is the movement of a fluid from an area of higher concentration to an area of lower concentration. 

APPLICATIONS OF GRAHAM'S LAW OF DIFFUSION:-

1. Separation of constituents of a gaseous mixture.
2. Determination of molecular mass and densities.
3. Dispersal of poisonous and foul smelling gases.
4. Marsh gas detector.
