Özet
We examine here the validity of the Pippard relations close to the melting point in the premelting region of hexadecane. For this verification, we analyze the observed data for the thermal expansivity ? p obtained for various pressures at constant temperatures of 302 and 325 K in this system. By calculating the isothermal compressibility T and the specific heat C p in the same pressure region of the premelting region of hexadecane, we obtain that C p varies linearly with ? p and also that ? p varies linearly with T for this system. This indicat es that some molecular organic compounds, such as solid hexadecane studied here, can exhibit -phase transitions prior to melting which are expected to verify the Pippard relations. © 2012 Hamit Yurtseven et al.
