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 to describe and predict properties of supercooled water. The equation is based on one of the leading theories (increasingly supported by experiments) - the second-critical-point scenario - that proposes a liquid-liquid critical point in 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. We have used the scientific IAPWS-95 formulation and existing experimental data to find the background functions at ambient pressure and then we have calculated some thermodynamic properties from the scaled equation. The extrapolations below the limit of homogenous nucleation are calculated and resu

Fuentevilla a Anisimov publikovali univerzální škálovací parametrickou stavovou rovnici založenou na 3D Isingově modelu. Rovnice může být použita k popisu a předpovědím vlastností vody v podchlazené oblasti pod hranicí homogenní nukleace, kde je velmi obtížné získat experimentální data. V článku byla použita vědecká formulace IAPWS-95 a existující experimentální data k nalezení funkce pozadí při atmosférickém tlaku. Ze škálovací rovnice byly vypočteny některé termodynamické vlastnosti vody. Byly vytvořeny a diskutovány aproximace vlastností pod hranicí homogenní nukleace.
