Answer 2

Differences between diffusion and osmosis :

1. Diffusion can occur in any medium while osmosis occurs money in liquid medium.

2. In diffusion, the diffusing molecules maybe solids, liquids or gases while osmosis involves movement of solvent molecules only.

3. In diffusion , semi-permeable membrane is not required while in osmosis semi-permeable membrane is required.

4. Diffusion is dependent upon the free energy of the molecules are diffusing substances only ; presence of other substances in the system is of no importance while though osmosis is the diffusion of solvent molecules only, get influenced by the presence of other substances in the system.

5. In diffusion ,an equilibrium in the free energy of diffusion molecules is achieved in the system while In osmosis, equilibrium in the free energy of solvent molecules is never received.
