The rms speed of molecules of an ideal gas is `v_(rms)`. Obtain the expression for rms value of relative speed for all pair of molecules in a gas sample.

The rms speed of a gas molecule is

The rms speed of a gas molecule is

The rms speed of gas molecules =________.

Initially, the translational rms speed of a molecule of an ideal gas is 463 m/s. The pressure and volume of this gas are kept constant, while the number of molecules is doubled. What is the final translational rms speed of the molecules?

Write the expression for rms speed, average speed and most probable speed of a gas molecule.

find the rms speed of oxygen molecules in a gas at 300K.
