Macleod’s relation

The surface tension varies with density p according to Macleod s relation (1)... 

Macleod s relation provides a number of important relationships for analyzing the effects of molecular weight, glass transition, phase transition (crystallization), and chemical constitution on surface tension, as discussed below. 

Macleod s relation also provides relationships for the effects of glass and crystal-melt transitions. At the glass transition, the surface tension is eontinuous, but its temperature coefficient is diseontinuous. (d y/dT) below the glass temperature, Tg, is related to (d y/dT) above T, (1) by...

Pure Liquids An approach suggested by Macleod [Macleod, D. B., Trans. Faraday Soc., 19 (1923) 38] and modified by Sugden [Sug-den, S. J., Chem. Soc., 125 (1924) 32] relates C to the liquid and vapor molar densities and a temperature-independent parameter called the parachor P...
