Which of the following diffuses fastest and which the slowest?Solid, Liquid, GasGive reasons for your answer.


Gases diffuse fastest and solids diffuse slowest when we compare solids, liquids, and gases.

Gases diffuse fast because the force of attraction between their particles is very low or negligible and they have huge spaces between the particles. The force of attraction between the particles of solids is very strong and there is no intermolecular spaces between the particles due to their compact arrangement. As a result, the rate of diffusion in solids is slowest.
