Imagine this... you just got back into the locker room from gym class. And to make to worse, today was the mile run...
HEY girls listen up! I want you all to shower, get rid of that sweat, and get out of this locker room in 10 minutes!!
Well if you spray it here how will it get around the whole locker room so that it can get rid of the stink?
it sure does smell in here because of all of the sweat.
Well lets ask Mr.Shnitzelbaum the science teacher about it.
Yeah. I will take out my perfume and spray it.Maybe it will help.
We wanted to ask you how we can get our perfume to disperse into the locker room?
Well its a concept that has two parts called diffusion and osmosis.This is a seventh grade subject but I will give you a brief understanding of each concept.
Actually there is nothing you have to do to make the perfume disperse because it happens on its own due to diffusion. Diffusion is a process where molecules go from an area of high concentration to an area of low concentration to reach an equilibreum.
For example take the perfume. When you spray it it has to travel from an area of high concentration which is where you sprayed it to an area of low concentration which is the other air around it.
Osmosis and diffusion
The two concepts osmosis and diffusion are very similar but osmosis includes water and something has to travel across a semipermeable membrane. Osmosis is the movement of water across a semipermeable membrane from an area of high concentration to an area of low concentration.
Take the example of an egg in vinegar. The vinegar passes through the membrane and changes something about the membrane and changes the composition of the egg.
