show that RMS velocity of a gas molecule is directly proportional to square root of absolute temperature.
Dear Student,
represents expression for r.m.s velocity of gas molecules.

Expression for r.m.s velocity:
Let pressure exerted by one mole of an ideal gas
volume of one mole of the gas.
absolute temperature.
Pressure exerted by gas is given by,
where mass of one mole(molecular weight) of the gas.
But for one mole of an ideal gas,
represents expression for r.m.s velocity of gas molecules.
As and in eqn- are constant,
