The presence of this quantity gives rise to an angle described by Young's equation.
The presence of this quantity gives rise to an angle described by Young's equation. Measured using the De Noüy ring method and predicted by the Eötvös rule, differences in this quantity lead to mass transfer in the Gibbs-Marangoni effect. "Tears of wine" and meniscuses are caused by this property, which is decreased by surfactants. Arising from unbalanced intermolecular forces, it allows certain insects to walk on water. For 10 points, name this property of liquids that causes falling drops to be spherical, and leads to capillary action.
