Do solids diffuse with each other??? Explain why

Chapter - Matter In Our Surrounding

No they do not diffuse. An inherit characteristic of solids is that their molecules are tightly packed together giving it a fixed shape. For this very reason, solids are not able to diffuse into one another since diffusion will only occur if molecules are free to move and not tightly packed such as in the case of most fluids and gases.

Hope this helps :)

solids ion are tightly packed with each other due to this property they are unable to diffuse to each other
diffusion is the process which is carried out between the molecules or ions which are loosely bound to each other as in liquid and gasses therefore the solids are unable to diffuse with eachother.
