surface tension of supercooled water no Inflection Point down to 25 c
Journal of Physical Chemistry Letters, 2014Co-Authors: Jan Hrubý, Radim Mareš, Václav Vinš, Jiří Hykl, Jana KalováAbstract:A dramatic increase in the surface tension of water with decreasing temperature in the supercooled liquid region has appeared as one of the many anomalies of water. This claimed anomaly characterized by the second Inflection Point at about +1.5 °C was observed in older surface tension data and was partially supported by some molecular simulations and theoretical considerations. In this study, two independent sets of experimental data for the surface tension of water in the temperature range between +33 and −25 °C are reported. The two data sets are mutually consistent, and they lie on a line smoothly extrapolating from the stable region. No second Inflection Point and no other anomalies in the course of the surface tension were observed. The new data lies very close to the extrapolated IAPWS correlation for the surface tension of ordinary water, which hence can be recommended for use, e.g., in atmospheric modeling.

Second Inflection Point of the Surface Tension of Water
International Journal of Thermophysics, 2012Co-Authors: Jana Kalová, Radim MarešAbstract:The theme of a second Inflection Point of the temperature dependence of the surface tension of water remains a subject of controversy. Using data above 273 K, it is difficult to get a proof of existence of the second Inflection Point, because of experimental uncertainties. Data for the surface tension of supercooled water and results of a molecular dynamics study were included into the exploration of existence of an Inflection Point. A new term was included into the IAPWS equation to describe the surface tension in the supercooled water region. The new equation describes the surface tension values of ordinary water between 228 K and 647 K and leads to the Inflection Point value at a temperature of about 1.5 °C.

Second Inflection Point of water surface tension
Applied Physics Letters, 2006Co-Authors: B. WeiAbstract:The classical molecular dynamics method is applied to simulate the surface tension of water over the wide temperature range from 193to398K. The results show that the temperature dependence of surface tension obviously increases in supercooled region, and there exists a second Inflection Point in the surface tension-temperature curve at about 303K similar to the first one at 525K, which confirms the conjecture based on the experimental measurements. When the temperature approaches 180K, the simulated surface tension displays a sharp rise like the anomalies of some bulk thermodynamic properties.
