Graham's Law of Effusion states that the rate of effusion (or escape) of a gas is inversely proportional to the square root of its molar mass.
This is the process by which gas particles pass through a tiny opening from a region of high pressure to low pressure.
This refers to the spreading out or intermingling of substances due to their kinetic properties.
It is the weight of one mole (6.022 x 10^23 molecules) of any chemical substances calculated in grams per mole (g/mol).
