Second-order phase transitions in water

VitalyA.Prisyazhniuk

Piecewise approximation analysis of experimental data for the isobaric heat capacity Cp = f (T) dependence for water revealed points of the second-order phase transition (PT2). In the temperature range of 273K – 373K (00C - 1000Ñ) there were found five such points and the temperature values initiating the PT2 were calculated. The validity of determining the critical points is corroborated by the published experimental data on anomalous properties of water at these points.
