Detailed explanation-1: -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.

Detailed explanation-2: -Graham’s law of diffusion (also known as Graham’s law of effusion) states that the rate of effusion a gas is inversely proportional to the square root of its molar mass. Often, it is used to compare the effusion rates of two gases.

Detailed explanation-3: -Graham’s law states that the rate of effusion of a gas is inversely propertional to the square root of the density of the gas.

Detailed explanation-4: -rate(gas A) × √molar mass(gas A) = rate(gas B) × √molar mass(gas B) This means that the relative rate of diffusion of two gases can be used to determine their relative molecular mass (or molar mass).

Detailed explanation-5: -Diffusion is directly proportional to temperature as it increases the kinetic energy of the molecules and inversely proportional to density of the substance. On increasing the temperature, the diffusion increases and on increasing the density of substance, the diffusion decreases and vice versa.
