Question

Why do gas diffuse very fast

Answer 1

gases have large intermolecular spaces and less force of attraction between  their particles,because they have large amount of kinetic energy,so that particles move randomly. so molecules of gas move faster hence making diffusion rate more faster.

Answer 2

since, The kinetic energy of the particles is very high in the vapour state , these particles readily mix up with the particles of Air. Gases intermolecular space is very high as compared to solid and liquids Due to this reason The molecules of gas moves in a faster rate , hence making diffusion rate more faster.
