Crossover Equation and the Vapor Pressure of Supercooled Water

Recently, Fuentevilla and Anisimov have published a scaled parametric equation of state that is universal in terms of theoretical variables and belongs to the three-dimensional Ising-model class of universality. The equation can be used for description and prediction of properties of supercooled water. The main advantage of the scaled equation mentioned above is the possibility to predict some properties of supercooled water below the limit of homogenous nucleation, where it is very difficult to obtain experimental data. This equation has been used to predict the behavior of the isobaric heat capacity in the range 150 K to 233 K, and from a knowledge of the isobaric heat capacity, calculations of the vapor pressure in the range from 123 K to 273 K have been carried out.
