Results of measurements of the specific heat, enthalpy, and average specific heat of copper are reported. Specific heat was measured in the range 295-903 K by the continuous adiabatic heating method with an error of 1%. Enthalpy and average specific heat were measured in the range 1262-1986 K by the drop method with an error of 1%-1.5%. The results are approximated by an equation in the range 298.15-2000 K, and the heat of melting ΔH m =13.59 kJ mol - 1 , the entropy of fusion AS f = 10.01 J mol - 1 K - 1 , and the specific heat of the melt c p = 36.3 J mol - 1 K - 1 were calculated.
