WebSurface tension. The work which is required to increase the size of the surface of a phase is referred to as the surface tension. As a measure of work per unit area or force per wetted length, surface tension has the unit mN/m and is designated by the symbol σ (lower case sigma).. If the phase is solid, the equivalent term surface free energy is normally used. WebMar 21, 2007 · A method is proposed for determining the surface tensions of a solid in contact with either a liquid or a vapor.

Surface Tension, Surface Free Energy, and Wettability

WebA sessile droplet can deform the surface of a soft solid not only with its weight. The surface tension pulls up a ridge at the perimeter of the drop, and the capillary pressure embosses a quasi-spherical dimple underneath the drop. This holds for the case of a bulk solid. However, if the solid forms a film with thickness comparable to the ... Several effects of surface tension can be seen with ordinary water: 1. Beading of rain water on a waxy surface, such as a leaf. Water adheres weakly to wax and strongly to itself, so water clusters into drops. Surface tension gives them their near-spherical shape, because a sphere has the smallest possible surface area to volume ratio.
