Abstract

The surface tension of pure liquid mercury in the temperature range 273 K to 523 K (0 °C to 250 C°) was calculated using our previously reported equation. The results were compared with the experimental data and showed a good agreement. The surface tension of mercury decreases linearly with temperature, confirming a negative slope, and therefore shows the usual linear temperature dependence. The calculated surface excess entropy (0.21) is in excellent consistence with the experimental value (0.22). The surface tension also was calculated for many d-block metals (Ti, Zr, Fe, Co, Ni, Cu, Zn, Cd, Ag, Au, Pd, and Pt) at their melting points. The calculated values were compared with the existing experimental data.
