Define diffusion
Diffusion is the spreading of particles of a gas, or of any substance in solution, resulting in a net movement from a region where they are of a higher concentration to a region with a lower concentration

The greater the difference in concentration...
..., the faster the rate of diffusion
2 of 5
Give an example of diffusion in the body
Oxygen into cells for repsiration
