Thermomechanical subdivision of internal energy of some noble gases on the ideal gas line

A calculation-theoretical procedure was developed by using a thermomechanical model of atomic substance for subdivision of the internal energies of neon, argon, krypton and xenon into individual components at their ideal gas lines. The calculations are made using the energy balance equation of phenomenological thermomechanics and generalized experimental data on thermal properties of the above-mentioned substances. They have shown that thermal, repulsive and attractive energies of the enumerated atomic substances increase nearly linearly, as temperature rises in full compliance with theoretical propositions of phenomenological thermomechanics; while, on the contrary, spin energy decreases almost linearly. The vibrational energy of longitudinal and transverse elastic waves is about zero as like for thermomechanical substance. Deviations of design values from those interpolated generalized experimental data do not exceed 2.17%. The follow conclusion can be drawn: the obtained results have practical implementation in cryogenic engineering.
