Dear student
Root mean square velocity (RMS value)is the square root of the mean of squares of the velocity of individual gas molecules. T = Temperature in Kelvin. Average velocity is the arithmetic mean of the velocities of different molecules of a gas at a given temperature.

- Root mean square velocity → The square root of the mean of squares of the velocity of individual gas molecules.
μR.M.S.=M3RT
Whereas,
R is the gas constant.
T is the temperature (in K).
M is the molar mass of the gas.
- Average velocity → The arithmetic mean of the velocities of different molecules of a gas at a given temperature.
μav.=πM8RT
Whereas,
R is the gas constant.
T is the temperature (in K).
M is the molar mass of the gas.
