surface tension

surface tension

(OP)
why does surface tension decreases with temperature. dowe  have mechanistic explanation for it.

RE: surface tension

Surface tension of liquids is exactly the same thing as suface energy in solids and is a due to the attraction between molecules that cause a material to be a liquid or solid rather than a gas (no attraction between molecules). Surface tension decreases with temperature up to the boiling point where surface tension approaches zero.

RE: surface tension


The surface tension is zero at the critical point, not the boiling point.
