Surface Tension of Supercooled Water: On The Way

Popis výsledku v původním jazyce

For a limited time, pure liquids can remain liquid even deep below the freezing point. Liquid below its equilibrium freezing point is metastable and it is called the supercooled liquid. Supercooled liquid water in small macroscopic samples was observed down to 240 K. Surface tension is an important property in case of small droplets, capillary flows etc. It governs the process of nucleation. Surface tension is of critical importance for estimation of nucleation and growth rates of droplets of supercooled water. Contemporary accurate relation for surface tension, adopted by the International Association for the Properties of Water and Steam (IAPWS, 1994), is only applicable above the triple point temperature. Only two datasets (Hacker, 1951, Floriano and Angel, 1990) exist for the surface tension of supercooled water. These datasets are mutually inconsistent. Therefore, a project was started to obtain new measurements.
