Pressure Dependence of the Thermodynamic Quantities in Phase II of Solid Benzene
The thermodynamic quantities such as the thermal expansion (αp), isothermal compressibility (KT) and the specific heat (CP − CV), 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 usi...

| Summary: | The thermodynamic quantities such as the thermal expansion (αp), isothermal compressibility (KT) and the specific heat (CP − CV), 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 αp, KT and CP − CV 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 pressure, as expected, which can be compared with the experimental measurements for the solid phase II of benzene. We find that the Pippard relations are validated within the pressure range considered, in particular, at high pressures for the solid phase II of this molecular crystal. |
