Question

Why do gases diffuse faster

Answer 1

Gases diffuse faster because the molecules in the gases are free in state. There is large intermolecular spaces between the molecules of the gases. Gases are rigid and they don't have definite shape.

Answer 2

As we know ,gases have large intermolecular spaces and less force of attraction between them. They have large amount of kinetic energy too.Due to the large amount of kinetic energy, the particles moves randomly . Due to this the molecules of gases move more faster, hence making diffusion rate more faster.
