Özet

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 CCl4 which can be verified experimentally.
