Which of the two diffuse faster a liquid or a gas ?

Which of the gases diffuses faster among N_2,O_2 and CH_4 ? Why?

Why do gases diffuse faster than solids or liquids ?

The rate of diffusion of a gas is

The molecular weight of a gas that diffuses twice as rapidly as a gas with molecular weight 64, is

(A): Gas with lower molecular weight will effuse or diffuse faster than the gas with higher molecular weight. (R) : Kinetic energy of any gas is independent of temperature.

Write an activity which shows the rate of diffusion of liquids.

Give two characters of a liquid.

Two gases have densities 0.388 g L^(-1) and 0.097 g L^(-1) . What is the rate of diffusion of the first gas, if the second gas diffuses at the rate 10 cc s^(-1) under similar conditions ?
