Liquid metal surface energy correlations

In Figure 6.7, different interfacial tensions or energies of metals are correlated with the fusion temperature in the form 7 fus-Vrm. In general the ratio of the average surface energy of the solid to the surface tension of the liquid is around 1.2... 

This equation shows that the surface energy per atom correlation between the surface energy per atom and the energy of sublimation (or evaporation) is expected provided mi is constant. Such correlations hold well for the solid and liquid surfaces of metallic bodies and also for the liquid surfaces of oxides and halides (see Figures 4.1,4.9 and 4.10). 

The surface energies of a large number of liquid metals are observed to follow this correlation, with C = 0.16 x 10 when is expressed...
