So diffusion occurs when molecules move from an area of high concentration to an area of low concentration, usually happens in a solution, such as a water -based solution.

So an example that i've got for you is steeping tea.
00:20
So i don't know if any of you are tea drinkers, but if we draw, if we've got this mug of tea, and this is a see -through mug, so that we can see what's going on here.
00:30
But if we have this mug of tea, and let's say that we put it, put our tea bag in it.
00:38
So at the beginning, we initially have all of our tea molecules are concentrated, high concentration inside the tea bag, all of the molecules that give the tea its flavor and its color.

And what happens is over time, they're going to start seeping out into the water...
