Question

explain diffusion with example?

Answer 1

Hi @friend
________
--------------
Term used in physical chemistry to describe at least 3 similar process ; the spontaneous mixing of gases or liquids when brought i into contact without mechanical mixing or stirring ; the spontaneous passage of fluids through membranes ; and the spontaneous passage of dissolved materials both through the materials in which they are dissolved and also through membranes.

One importance application of the D. principle is for the separation of isotopes, particularly those of uranium . When uranium hexafluoride is forced through a porous plate the ratio of the 235 and 238 isotopes is changed slightly .With sufficient numbers of passages ,the separation is nearly complete.
