What is a real life example of simple diffusion?

Answer 1

Perfume. If you spray any type of perfume in one area of a room, soon you can smell it at the other side of the room. When first sprayed, the perfume is highly concentrated in one area. Then diffusion kicks in and the particles move from an area of high concentration to an area of low concentration until it there is an equal concentration throughout.

Answer 2

One real-life example of simple diffusion is the movement of oxygen molecules from the alveoli in the lungs into the capillaries surrounding them. Oxygen moves from an area of high concentration in the alveoli to an area of low concentration in the capillaries through simple diffusion, allowing oxygen to be transported through the bloodstream to cells in the body that need it for cellular respiration.

Answer 3

You can go to http://www.its.caltech.edu/~brokawc/Bi145/Diffusion.htmlto find the answer to this question. It gives you the formulas and chemical examples in the first part, and in the second part, they give you a physical example of phosphate in the ocean.
