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 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.

Pressure dependence of the heat capacity near the melting point in benzene Yurtseven, Hasan Hamit (2017-09-01) 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.
Pressure Dependence of the Raman Modes Related to the Phase Transitions in Cyclohexane Yurtseven, Hasan Hamit (2015-03-01) The pressure dependence of the Raman frequencies for the v(21) mode is studied by using the volume data at room temperature close to the transitions among the phases of III, IV and V in cyclohexane. By determining the pressure dependence of the mode Gruneisen parameter gamma T in the phases and taking the average values, the Raman frequencies of those modes associated with the phase transitions are predicted through the volume data in cyclohexane. Our predicted Raman frequencies agree with those observed ex...
Calculation of thermodynamic quantities for carbon tetrachloride (CCl4) close to the III-IV phase transition Yurtseven, Hasan Hamit (2011-01-01) We calculate the thermal expansion alpha(p), isothermal compressibility K-T and the specific heat, C-p-C-v as a function of pressure using the observed V-P data at room temperature close to the phase transition in CCl4. Calculated K-T, alpha(p) and C-p-C-v decrease as the pressure increases from phase III to phase IV in this molecular crystal system, as expected. On the basis of our calculations of the K-T, alpha(p) and C-p-C-v, the Pippard relations are established close to the III-IV phase transition in C...
Critical behaviour of the thermodynamic quantities near the melting point in the solid phase of hexadecane Yurtseven, Hasan Hamit (2008-01-01) We study here critical behaviour of the thermodynamic quantities such as thermal expansivity alpha(p), isothermal compressibility k(T) and the specific heat C-p close to the melting point in solid hexadecane. By analyzing experimental data for the thermal expansivity measured at various pressures for constant temperatures of 302 and 325 K, we calculate the pressure dependence of the isothermal compressibility k(T) and specific heat C-p near the melting point in solid hexadecane. We then establish the Pippar...
alpha-beta Transition in Quartz: Temperature and Pressure Dependence of the Thermodynamic Quantities for beta-Quartz and beta-Cristobalite as Piezoelectric Materials Lider, M. C.; Yurtseven, Hasan Hamit (2014-12-01) Temperature and pressure dependencies of the thermal expansivity (alpha(p)), isothermal compressibility (j(T)) and the specific heat (C-p - C-v) are studied for piezoelectric materials, in particular, for beta-quartz. By analyzing the temperature (at 1 atm) and pressure (at 848 K) dependence of the observed volume V from the literature, the thermodynamic functions (ap, jT and C-p - C-v) are obtained and the Pippard relations (C-p - C-v vs. Vap and ap vs. j(T)) close to the transition from the beta-quartz to...
