Question

why diffusion is very fast in gases slower in liquids and slowest in solids

Answer 1

Answer:

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

Answer:

Hey dear,

this is because gas molecules have more kinetic energy and are smaller than liquid molecules. diffusion in liquids is slower because the particles in a liquid move more slowly.

hope this helps
