English
wsmo`s, equiv. to w^sis impulse, fr. wqei^n to push.] (Chemical Physics) (a) The tendency in fluids to mix, or become equably diffused, when in contact. It was first observed between fluids of differing densities, and as taking place through a membrane or an intervening porous structure. An older term for the phenomenon was {Osmose}. Note: The more rapid flow from the thinner to the thicker
fluid was then called {endosmosis} (formerly
{endosmose}), and the opposite, slower current,
{exosmosis} (formerly {exosmose}). Both are, however,
results of the same force. Osmosis may be regarded as a
form of molecular attraction, allied to that of
adhesion. See also {osmotic pressure}.
(b) The action produced by this tendency.
[1913 Webster]
