Expert Answer
Diffusion is a process by which the molecules move from a region of higher concentration to a region of lower concentration.
It should be noted that diffusion is different from osmosis as osmosis exclusively includes movement of water, whereas diffusion involves the movement of particles generally through a membrane.
The following example explains the significance of diffusion of gases in water :
Breathing :
- While we breathe in, the oxygen from the air which we breathe diffuses from the lungs to the bloodstream.
- The oxygen which was breathed in the gaseous state is now in the liquid state mixed in the bloodstream.
- Thus making diffusion of gases in liquid (oxygen gas from our lungs to the bloodstream) one of the essential phenomena
