Surface tension of the liquid force is occurring on the surface of the liquid is exposed to the other or to the surface of the liquid, solid, with sufficient binding energy between molecules. Which is associated with a strong adhesive and pressure-tight connections, causing a similar thin sheets that can be with a tensile. There is a parallel with the surface of the liquid and the direction perpendicular to the liquid touching the border. When the temperature is increased, the liquid surface tension is reduced.
