Gas state of the substance at low temperatures

The classical Boltzman statistics is shown to be applicable for gaseous state of substance at low temperatures, conditions of applicability being observed the better, the lower temperature is. Limiting values of some thermodynamical characteristics for gaseous state at T→0 K are considered. Values of thermodynamical characteristics for real gases at T→0 K are stated to approach the values peculiar to the model of monoatomic ideal gas, and the gaseous state at T→ 0 v is found to be the only limiting state for which the model of ideal gas is maximally true
