A thermodynamic description of data for pure Pb from 0 K using the expanded Einstein model for the solid and the two state model for the liquid phase

Thermodynamic data for the crystalline and liquid phases of pure lead were critically assessed. A thermodynamic description was obtained using an extended Einstein model for the crystalline phase and a two state model for the liquid phase. The assessment was carried out through careful analysis of the experimental data published in the scientific literature. Additional measurements using enthalpy drop were also carried out in the present work to remove ambiguities in published experimental data.
