Parallel tempering Monte Carlo calculations on the Li+Arn microsolvation clusters have shown that the two peaks appearing in the heat capacity curve as a function of temperature correspond to the melting of the second and first solvation shells.
AbstractThe low-temperature heat capacity of zinc chromite (ZnCr2O4) was measured between 6.5 K and 400 K using adiabatic calorimetry, and some thermochemical functions (CP(T),S(T), S°298,H(T)-H(0)) were derived from the results. The standard entropy (S°298= 128.6±0.3 J mol-1K-1) for zinc chromite was calculated from the results. Our calorimetric measurements indicate one extremely large anomaly in the heat capacity curve at ∼12.3 K which is related to the cubic-tetragonal transition in ZnCr2O4.
The heat capacity of Monel metal over the range − 183° to 25 °C. has been measured in an adiabatic calorimeter. By differentiation of the equation representing the heat capacity curve, an equation for the specific heat over this range is obtained and values at various temperatures calculated. The specific heat at 20 °C. is found to be 0.0997.
