Theoretical Research on Temperature Dependence of the Specific Heat at Constant Volume for Liquid Metals

Based on the experimental results, Grover[1] presented an approximation formula for the specific heat at constant volume of liquid metals versus temperature: cV3R-RT/Tm, where T is the temperature, Tm is the melting temperature, R is the gas constant, is an empirical constant, with value of 0.11~0.24, its average value is about 0.15. In this paper, the approximation relation is deduced by using the Lennard-Jones-Devonshire theory.
