WebApr 4, 2024 · The symbol gamma is used by aerospace and chemical engineers. γ = C P C V = c P c V where C is the heat capacity and c the specific heat capacity (heat capacity per unit mass) of a gas. The suffixes P and V refer to constant pressure and constant volume conditions respectively. The only possible motion of an atom in a monatomic gas is translation (electronic excitation is not important at room temperature). Thus by the equipartition theorem, the kinetic energy of a single atom of a monatomic gas at thermodynamic temperature T is given by , where kb is Boltzmann's constant. One mole of atoms contains an Avogadro number () of atoms, so that the energy of one mole of atoms of a monatomic gas is , where R is the gas constant.
