Starting from the equation of state of the Clapeyron gas, it is shown that the temperature of a monatomic molecule of radius and mass moving with velocity is equal to , where: l are the length of a molecule without collisions, the Boltzmann constant, the kinetic energy of the molecule. The physical meaning of the temperature of a molecule should be understood as the kinetic energy that it has in the path without collisions l. The dimension of temperature coincides with the size of energy, but quantitatively the energy differs by the presence of a dimensionless factor , characterizing the motion of a molecule in fractions of its radius. Based on the temperatures of the individual molecules and their relative amounts contained in the gas, a formula is proposed for the overall gas temperature, for any, even nonequilibrium, distribution. The physical meaning of the gas temperature is determined by the product of the mean kinetic energy, the average mean free path of its molecules, and their size.
