Correlation between surface tension and critical temperatures of liquid metals.
The inter-relationship of surface tension sigma, molar volume V, and critical temperature Tc has been examined using experimental values for eighteen liquid metals. Hard-sphere diameters a correlate with the equation a(5/2) = 8.9733 x 10(-19) V (sigma/Tc)(1/4) - 1.0459 x 10(-25). Unknown Tc may be estimated using surface tension and liquid density values.
