摘要

A linear correlation between the specific heat Cp and thethermal expansion a p is established here for constant tempera-tures close to the melting pressure in ammonia solid III. For thiscorrelation, the experimental data for the isothermal compress-ibility KT is analysed according to a power-law formula withthe critical exponent y and, the Cp and a p are calculated as afunction of pressure near the melting point in ammonia solid III. Values of the entropy changes with the temperature, whichare extracted from linear plots of Cp against a p, decrease as thetemperature increases for the ammonia solid III prior to melting.
