Q. Graham’s law is correlated with :
(a) Diffusion
(b) Osmosis
(c) Osmoregulation
(d) Absorption
Solution :
Correct option : A Graham’s law of effusion also known as Graham’s law of diffusion expresses the relationship between the rate of diffusion or effusion of a gas and its molar mass. The law states that under similar conditions of temperature and pressure, the rates of diffusion of gases are inversely proportional to the square roots of their densities. Hence option A is correct.
