So this one is actually super easy.
00:03
You have two solutions.
00:05
They're separated by a semi -permeable membrane.
00:11
This membrane allows water in and out, but nothing else really, right? okay, well, okay, semi -permeable membrane.
00:27
So water will move in and out.
00:29
So this is a semi -permeable membrane.
00:43
Okay.
00:44
You have solution a and solution b.
00:54
Solution a has 100 molecules of glucose.
01:06
I'm gonna make these red, and there are these big red molecules.
01:10
They're not moving anywhere.
01:12
I tell you right now they don't cross semi -promobile membranes.
01:14
They're way too big.
01:16
And we've got 100 of those...
