Molar heat capacities and molar enthalpies of fusion of the solvates Zn(NO3)2 . 2·24 DMSO, Zn(NO3)2 . 8·11 DMSO, Zn(NO3)2 . 6 DMSO, NaNO3 . 2·85 DMSO, and AgNO3 . DMF, where DMSO is dimethyl sulfoxide and DMF is dimethylformamide, have been determined over the temperature range 240 to 400 K. Endothermic peaks found for the zinc nitrate solvates below the liquidus temperature have been ascribed to solid phase transformations. The molar enthalpies of the solid phase transformations are close to 5 kJ mol-1 for all zinc nitrate solvates investigated. The dependence of the molar heat capacity on the temperature outside the phase transformation region can be described by a linear equation for both the solid and liquid phases.

Ultrasonic velocities and volumetric heat capacities at constant pressure were measured at 298.15 K for water + tetrahydrofuran mixtures over the whole concentration range using pulse–echo–overlap equipment and a flow microcalorimeter respectively. Isentropic and isothermal compressibilities and heat capacities at constant pressure and at constant volume were derived from the results in combination with the results of previous studies of thermal expansivities and excess volumes. The significance of the excess compressibilities and excess heat capacities is discussed in terms of molecular interactions.
