Given,
The average kinetic energy of a molecule is given by, where k is the Boltzmann constant and Tis the absolute temperature of the gas.
The rms speed of molecules is given by
The average kinetic energy of a gas's particles is inversely related to its temperature. As the gas warms, the particles must travel more quickly since their mass is constant.
The average kinetic energy (K) is equal to one half of the mass (m) of each gas molecule times the RMS speed (vrms) squared.
