(
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 .
