उत्तर
Gases diffuse fastest and solids diffuse slowest when we compare solids, liquids and gases.
Explanation: Gases diffuse fast because the force of attraction between their particles is very low or negligible and there are vast spaces between the particles. The force of attraction between the particles of solids is very strong and there is no space between the particles due to their compact arrangement. As a result, rate of diffusion in solids is slowest.
