ideal gas

(Also called perfect gas.) A gas for which the potential energy of interaction between molecules is independent of their separation and hence is independent of gas volume.

Thus, the internal energy of an ideal gas depends only on its temperature. To a very good approximation, atmospheric gases at normal terrestrial temperatures and pressures are ideal.
