An ideal gas isIdeal Boltzmann gas referred to as a gas in which the interaction is completely neglected between the particles composing the gas. Usually such an approximation is associated with a sufficiently low density or rarefaction of the condensed medium. On the neglect of the interparticle interaction the problem to calculate the partition function Z is greatly simplified and, due to the identity of the particles in the gas, can be reduced to determining the partition function of a single particle. From this point of view an ideal gas is the simplest physical system.

摘要

An ideal gas isIdeal Boltzmann gas referred to as a gas in which the interaction is completely neglected between the particles composing the gas. Usually such an approximation is associated with a sufficiently low density or rarefaction of the condensed medium. On the neglect of the interparticle interaction the problem to calculate the partition function Z is greatly simplified and, due to the identity of the particles in the gas, can be reduced to determining the partition function of a single particle. From this point of view an ideal gas is the simplest physical system.
