Using the concepts of instantaneous normal modes to calculate the heat capacities of liquid metals at high temperatures
Annotation
In this article, based on the concept of instantaneous normal modes, a simple semiempirical formula for calculating the heat capacity of liquids is proposed. The calculation results were compared with experimental data on the heat capacity of sodium, lead, and bismuth. It is shown that the formulas make it possible to assess properties in the high-temperature region with satisfactory accuracy.
