Pressure Dependence of Molar Volume near the Melting Point in Benzene

The pressure dependence of the molar volume was at constant temperatures close to the melting point in benzene. The molar volume of benzene was calculated using experimental data for the thermal expansivity for constant temperatures of 25°C, 28.5°C, 40°C, and 51°C at various pressures for both the solid and liquid phases. The predictions are in good agreement with the observed volumes in both the solid and liquid phases of benzene. The predicted values of the molar volume for a constant temperature of 28.5°C in the liquid phase of benzene agree well with experimental data in the literature.
