how to find the average kinetic energy. To figure the total kinetic energy you multiply the average kinetic energy by the number of molecules you have which is nNA where n is the number of moles. Some molecules will be traveling faster and some more slowly.
As stated in the kinetic-molecular theory the temperature of a substance is related to the average kinetic energy of the particles of that substanceWhen a substance is heated some of the absorbed energy is stored within the particles while some of the energy increases the motion of the particles. EqT eq is the temperature in Kelvin. The average kinetic energy K is equal to one half of the mass m of each gas molecule times the RMS speed v rms squared.

K s K g E b where K s is the average kinetic energy of a solid molecule K g is the average kinetic energy of a gas molecule at the same temperature and E b is the energy stored in the inter molecular bonds between the molecules of the solid. Eqk_rmB eq is the Boltzmann constant whose value is eq138. The formula for calculating kinetic energy KE is KE 05 x mv2. See Coulson and Richardson 1999.
