Question

Can you please tell me does solid diffuse in another solid ? and iam request you to give more examples of diffusion in solid,liquid and gases.Urgent

Answer 1

Yes, solid does diffuse in another solid, but since its rate of diffusion is very slow, we cannot see it. Example of gas diffusing in gas - when you spray perfume,the smell spreads everywhere

Answer 2

Diffusion in solid takes place , but at very low rate and takes a lot of time .. there is a good example - when you write on blackboard with chalk then , after 2~3 weeks you can observe it will become difficult to remove the chalk . You will need water and scrubber to do so.
