WebSurface tension is a direct measure of this energy loss per unit area of surface. If the characteristic molecular dimension is R and its area thus R. 2, then the surface tension is σ ∼ U/(2R) 2. Note that surface tension increases as the intermolecular attraction increases and the molecular size decreases. ...
