The heat capacity C-p is calculated as a function of pressure at constant temperatures of 25, 40 and 51 degrees C for the solid and liquid phases of benzene near the melting point. For this calculation, the observed molar volume from the literature are used at various pressures for constant temperatures indicated through the thermodynamic relations in the solid and liquid phases of benzene near the melting point.

Variation of the molar volume with the temperature and the Pippard relations near the melting point in benzene Tari, O.; Yurtseven, Hasan Hamit (2016-08-01) 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 expan...
Analysis of The Molar Volume as A Function of Pressure Close to The Melting Point in Ammonia Solid III Yurtseven, Hasan Hamit (2009-06-01) This study gives the calculation of the molar volume as a function of pressure for constant temperatures in ammonia solid III near the melting point. Using the value of the critical exponent gamma extracted from the experimental,data for the isothermal compressibility kappa(T). The molar volume calculated here decreases as the pressure increases on approach to the melting point. This critical behaviour can describe the observed behaviour of the molar volume near the melting point, as obtained experimentally...
Pressure Dependence of Molar Volume near the Melting Point in Benzene Yurtseven, Hasan Hamit (Tsinghua University Press, 2007-10-01) 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°...
Molar volume calculated at various pressures and the Pippard relations close to the melting point in benzene Yurtseven, Hasan Hamit (2016-03-03) The molar volume of solid and liquid benzene was calculated at various pressures (at constant temperatures), and the Pippard relations were examined close to the melting point in this organic molecule.The molar volume calculated is in good agreement with the observed data, which decreases as the pressure increases up to about 150 MPa. The Pippard relations are also valid within this pressure range at constant temperatures studied here for the solid and liquid phases of benzene.
Pressure Dependence of the Thermodynamic Quantities in Phase II of Solid Benzene Yurtseven, Hasan Hamit (2013-10-01) The thermodynamic quantities such as the thermal expansion (alpha(p)), isothermal compressibility (K-T) and the specific heat (C-P - C-V), are predicted at various pressures up to 26 GPa (T = 540 K) in the solid phase II of benzene using volume data from the literature. The Pippard relations are examined using the pressure dependence of alpha(p), K-T and C-P - C-V and the value of the slope dP/dT is deduced for the solid phase II of benzene. The thermodynamic quantities studied here decrease with increasing...
