Question

Write down the differences between diffusion and osmosis.

Answer 1

Osmosis	Diffusion
In osmosis, the solvent moves from a less concentrated solution to a more concentrated solution through a semi-permeable membrane.	In diffusion, the molecules of two or more substances mix spontaneously to form a homogeneous mixture. No semi-permeable membrane is present in this case.
It takes place only in the case of liquids.	It takes place in the case of liquids as well as gases.
It can be stopped or reversed by applying pressure.	It is a spontaneous process and cannot be stopped or reversed.
