Root mean square velocity is the measure of the velocity of gas particles that is used for solving problems. It is the square root of the average velocity-squared of the molecules in a gas. The formula for root mean square velocity is sqrt(3RT/Mm) where Mm is the molar mass of the gas in kg / mole, R is the gas constant, and T is the temperature in kelvin.

For an object moving at a variable velocity you:calculate the square of the velocityfind its mean valuecalculate its square root.If the velocity is constant then the RMS velocity has the same value.

Molecular velocity is defined as the velocity of a each molecule in a certain sample of gas. It can be expressed by means of root-mean-square velocity, average velocity and most probable velocity.

Gas velocity involves the variables of system temperature and molar mass of its molecules. Simplified, the velocity as a root-mean-square equals the square root of two-times the kinetic energy divided by molecular mass.
