The heat capacity of zinc has been determined by adiabatic calorimetry from 298.15 to 940 K. For crystalline zinc Cp,m increases from 25.47 J K−1 mol−1 at the former temperature to an evenly extrapolated value of 30.96 J K−1 mol−1 at the triple-point temperature 692.681 K (ITS-90). The estimated heat capacity increment of fusion is 2.46 J K−1 mol−1. For liquid zinc the heat capacity decreases from 33.42 J K−1 mol−1 at Tfus to 32.31 J K−1 mol−1 at 940 K. Thermodynamic function values have been derived and are tabulated for selected temperatures after revaluation of earlier low temperature results.
