what is the difference between diffusion and imbibition
Diffusion | Imbibition |
It can be the movement of any of molecules of either gases or liquids. | It is a type of diffusion in which water is absorbed by solids |
It depends on many factors like concentration gradient, temperature, permeability of membrane, Solubility, pressure etc | It depends upon affinity between adsorbent and liquid being adsorbed. |
No need of adsorbant for diffusion to occur | An adsorbant is required for imbibition to occur. |
