Heat Capacity of Reference Materials: Cu and W

Abstract

The CODATA Task Group on Thermophysical Properties is preparing a set of recommended values for the heat capacity, thermal expansion, and transport properties of key solids which are used in calibrating or checking measuring equipment. The present paper surveys selected data on heat capacity at constant pressure Cp of copper from 1 to 1300 K and tungsten from 1 to 3400 K. Selected values are tabulated for Cp and also for heat capacity at constant volume Cv. Interpolating functions are given for Cp.
