Differentiate between Diffusion in solids and Diffusion in liquids.
Diffusion in solids | Diffusion in liquids |
Diffusion in solids is a very very slow process. | Diffusion in liquids is fast as compared to solids but slow as compared to gases. |
The particles in solids are tightly packed and do not have high kinetic energy and therefore, can not move freely as force of attraction between the particles is very strong. | The particles in the liquid are less tightly packed as compared to solids and have little more kinetic energy than solids and can move as the force of attraction between the particles is less strong than solids. |
For Example: It becomes difficult to clean a blackboard if we write something on it and leave it uncleaned for sometime because some particles of chalk have diffused into the surface of blackboard. | For Example: The water gets purple if we place some of the crystals of potassium permanganate into it due to diffusion of particles in water. |
