osmosis

os-mo′sis

(ŏz-mō′sĭs)
,
Noun.
[NL., fr. Gr.
ὠσμός
, equiv. to
ὦσισ
impulse, fr.
ὠθεῖν
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
.
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.
