do the gaseous mixtures show osmotic phenomenon ????? ...

[Knoxy]

osmosis is like concept related to diffusion pressure deficit or chemical potential...

which is strictly the fluid property...and gases r also fluids...so ????

[Mr Skeptic]

Osmosis is strictly water-based diffusion, by definition. Diffusion of other things happens but isn't properly called osmosis, although some people do call it that anyways. And yes, gases diffuse.

Effusion is the name for gasses passing through a small aperture.

It is mediated by Graham's law, and can be applied to mixtures of gasses up-to a point.

Graham's law can be applied to purify gases in an analogue to reverse osmosis.
