Abstract:
The paper studies the size dependence of the surface tension at a weakly curved liquid-vapor interface. Statistical expressions for the first and the second corrections to the surface tension are derived with the use of expansion of the first of the equations of the hierarchy of Born-Green-Yvon into a series in terms of the curvature of the dividing surface. A method of approximate evaluation of the second correction by information on the properties of a planar liquid-vapor interface is suggested.

Surface Tension, Capillary Action, and Viscosity
The various IMFs between identical molecules of a substance are examples of cohesive forces. The molecules within a liquid are surrounded by other molecules and are attracted equally in all directions by the cohesive forces within the liquid. However, the molecules on the surface of a liquid are attracted only by about one-half as many molecules. Because of the unbalanced molecular attractions on the surface molecules, liquids contract to form a shape that minimizes the number...
Surface Tension and Surface Energy
Consider a beaker filled with liquid. The bulk molecules in the liquid experience equal attractive forces on all sides with the surrounding molecules. However, the surface molecules experience a net attractive force downward due to the bulk molecules. The surface of the liquid behaves like a stretched membrane,...
