Molar heat capacity and entropy of calcium metal

The heat capacity of calcium has been measured at 85 mean temperatures betweenT≈ 8 K andT≈ 369 K using an adiabatically-shielded calorimeter in an intermittent heating mode. AtT= 298.15 K, the recommended values for the molar heat capacity, molar entropy, and molar enthalpy increment referred toT= 0 are (25.77 ± 0.08) J·K⁻¹·mol⁻¹, (42.90 ± 0.11) J·K⁻¹·mol⁻¹, and (5811 ±12)J·mol⁻¹, respectively. The uncertainties are twice the standard deviation of the mean.
