 Surface tension |
Because the liquid state still involves
intermolecular forces at relatively close range, all liquids have
some limited physical properties in common. Representative of
these are:
Surface tension is the result of unbalanced forces which exist on the
surface of a liquid. Submerged molecules are tugged in all
directions by neighbors but those on the surface have no pull
upward on them. The result is like an elastic film, the strength
of which is related to intermolecular forces.
