Question

difference between diffusion and osmosis .

At least 5 points about each of them .

Answer 1

diffusion is movement of molecules or ions from higher to lower region concentration

osmosis is movement of molecules or ions from lower to higher concentration

Answer 2

Diffusion : It is the movement of all types of substances from the area of their higher free energy to the area of their lower free energy.

Osmosis : It is the movement of only solvent or water from its higher free energy or chemical potential to the area of its lower chemical potential when the solute particles are not allowed to diffuse.

Diffusion: It can operate in any medium.

Osmosis : It operates only in a liquid medium.

Diffusion : It is applicable to all types of substances: solids, liquids or gases.

Osmosis : It is applicable to only solvent part of a solution.

Diffusion : It does not require any semipermeable membrane.

Osmosis : A semipermeable membrane is a must for the operation  of osmosis.

Diffusion : It is purely dependent  upon the free energy of the diffusing substance.

Osmosis : It dependent upon the degree of reduction of free energy of one solvent over that of another.
