Calculation of the internal energy of neon, argon, krypton and xenon at their critical points using a thermomechanical model

摘要

The energy balance equation of phenomenological thermomechanics has been used to calculate thermal, repulsive, attractive, vibrational and spin energies of Ne, Ar, Kr, and Xe at their critical points. The obtained results show a good agreement with analogous calculated data for the thermomechanical substance. The discrepancies between them never exceed 4.9%. (C) 1999 Elsevier Science Ltd.
