Linear variations of the thermodynamic quantities in the liquid phase of carbon tetrachloride close to the melting point

Our linear plots of Cp against αp and also αp against κT give the values of the slope dPm/dT as ~ 8.5MPa/K and 9.5MPa/K, respectively, which can be compared with the experimental value obtained from a P-T phase diagram close to the melting point in carbon tetrachloride.
