diffusion

Diffusion is the natural movement of molecules from:

• Areas of low concentration to areas of high concentration

• Areas of high concentration to areas of low concentration

• Cold to hot environments

• Gaseous to liquid environments

From fastest to slowest rate of diffusion, which of the following is in the correct sequence?

• Solids, liquids, gases

• Liquids, gases, solids

• Gases, liquids, solids

• Gases, solids, liquids
