2. Molecular diffusion in solid is much faster than that in liquids
3. Particles movement from higher concentration to lower concentration takes place in diffusion process
4. According to Poiseuille's law, the permeability decreases with increase in temperature for flow of a gas through a given capillary
- b. Molecular diffusion in solid is much faster than that in liquids
