Apparent molar volumes and heat capacities of aqueous lithium chloride, rubidium chloride, and cesium chloride at temperatures from (278.15 to 393.15) K at the pressure 0.35 MPa

Apparent molar volumes V-phi and apparent molar heat capacities C-p,(phi) were determined for aqueous solutions of lithium chloride, rubidium chloride, and cesium chloride at molalities m = (0.02 to 1.0) mol(.)kg(-1), and at the pressure p = 0.35 MPa. Density measurements obtained with a vibrating-tube densimeter at temperatures T = (278.15 to 368.15) K were used to calculate V-phi values, and heat capacity measurements obtained with a twin fixed-cell, differential-output, power-compensation, temperature-scanning calorimeter at temperatures T = (278.15 to 393.15) K were used to calculate C-p,C-phi values.
