(*) curvature according to LaPlace's law.
Techniques to measure this quantity include the du Nouy method, which uses a platinum ring, and a method that can be used to prepare Langmuir-Blodgett films named after Wilhelmy. This quantity's variance with temperature is described by the Eotvos equation. The difference in pressure across the interface of two static fluids is twice this quantity times the mean (*) curvature according to LaPlace's law. It leads to mass transfer in the (*) Marangoni Effect and is lowered by micelle-forming substances called surfactants. For 10 points, name this property measured in dynes per centimeter that causes capillary action and the formation of a meniscus, and explains why some insects can walk on water.
