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 pressureCpof copper from 1 to 1300 K and tungsten from 1 to 3400 K. Selected values are tabulated forCpand also for heat capacity at constant volumeCv. Interpolating functions are given forCp.
