Özet

In this study, we calculate variation of the molar volume with the temperature at constant pressures (70.5, 85.2, 128 and 175.2 MPa) using the experimental data from the literature for the solid and liquid phases of benzene near the melting point. The calculated molar volume decreases in the solid phase as the temperature increases toward the melting temperature, whereas in the liquid phase just above the melting temperature it increases abruptly, as expected. By calculating the specific heat, thermal expansion and the isothermal compressibility from the molar volume, which increase with increasing temperature (at constant pressures), we construct the Pippard relations for the solid and liquid phases of benzene near the melting point.
