摘要：

Apparent molar volumes V-phi and apparent molar heat capacities C-p,C-phi, were determined for aqueous solutions of barium nitrate Ba(NO3)(2) at molalities in = (0.0025 to 0.2) mol(.)kg(-1), at T = (278.15 to 393.15) K, and at the pressure 0.35 MPa. Our Vphi values were calculated from densities obtained using a vibrating-tube densimeter, and our C-p,C-phi values were obtained using a twin fixed-cell, power-compensation, differential-output, temperature-scanning calorimeter. Our results were fitted to functions of m and T and compared with values from the literature. (C) 2004 Elsevier Ltd. All rights reserved.
