摘要：
The temperature-dependent heat capacity of vysotskite, PdS, has been determined for the first time by adiabatic, relaxation, and differential scanning calorimetry in a wide temperature range and standard thermodynamic functions of PdS have been calculated. The 298.15-K values thus obtained are= 43.65 +/- 0.09 J/(mol K),S degrees = 51.98 +/- 0.10 J/(mol K),H degrees(298.15 K) -H degrees(0) = 8.03 +/- 0.02 kJ/mol, and CYRILLIC CAPITAL LETTER EF degrees = 25.03 +/- 0.05 J/(mol K). Using the present results and data in the literature, we obtained Delta H-f degrees(PdS, 298.15 K) = -74.0 +/- 1.0 kJ/mol and Delta(f)G degrees(PdS, 298.15 K) = -68.7 +/- 1.0 kJ/mol.
