surface tension surface tension gsunil (Chemical) (OP) 25 Jan 06 14:00 why does surface tension decreases with temperature. dowe have mechanistic explanation for it. RE: surface tension Compositepro (Chemical) 27 Jan 06 13:03 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 25362 (Chemical) 26 Mar 06 12:30 The surface tension is zero at the critical point, not the boiling point.
