Surface Tension of Supercooled Water Determined by Using a Counterpressure Capillary Rise Method

Popis výsledku v původním jazyce

Measurements of surface tension of supercooled water reported by Hrubý et al. [J. Phys. Chem. Lett. 2014, 5, 425] did not show any anomalous temperature dependence of the surface tension of supercooled water. In the present work, this finding is confirmed using a counterpressure capillary rise method as well as through the use of the classical capillary rise method. In the counterpressure method, the liquid meniscus inside the vertical capillary tube was kept at a fixed position with an in-house developed helium distribution setup. A preset counterpressure was applied to the liquid meniscus, when its temperature changed from a reference temperature (30°C) to the temperature of interest, in order to keep the meniscus at a constant height. The combined relative standard uncertainty of the relative surface tensions is less than 0.18%. The new data between ?26 °C and +30 °C lie close to the IAPWS correlation for the surface tension of ordinary water extrapolated below 0.01 °C.
