Özet

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 Pippard relations (C-p vs. alpha(p) and alpha(p) vs. k(T)) for this molecular organic compound close to its melting point.
