Question

Difference between diffusion and osmosis.

Answer 1

The gradual passing of a liquid through a thin layer of material a membrane called as osmosis

Answer 2

diffusion:

Diffusion is a transport phenomenon tend to cause movement of molecules, substances, etc. from regions of high concentrations to regions of low concentrations.



osmosis:

the spontaneous net movement of solvent molecules through aselectively permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides. It may also be used to describe a physical process in which any solvent moves across a selectively permeable membrane (permeable to the solvent, but not the solute) separating two solutions of different concentrations.Osmosis can be made to do work.Osmotic pressure is defined as the external pressurerequired to be applied so that there is no net movement of solvent across the membrane. Osmotic pressure is a colligative property, meaning that the osmotic pressure depends on the molar concentration of the solute but not on its identity.
