Give the expression for the average kinetic energy of a molecule.

Explanation

Average kinetic energy of a molecule = `=(1)/(2)mv^(2)=((f)/(2))K_(B)T` where f = 3 for monoatomic gas, f = 5 for diatomic gas, f = 3x - y where x is the number of atoms and y is the number of independent relations among the atoms.
