diffusion folks is the movement of things from a gradient of higher concentration to lower concentration, which you just think about this as things tend to run downhill from higher concentration to lower concentration. They try and create equilibrium across space. So, you know, if you had a bunch of marbles on one side of a box, they're just imagine that these were water molecules because of the charges between those hydrogens and oxygens, there's a tendency for those marbles to spread out and essentially take on a fairly even confirmation. That's basically just diffusion across a space. Water molecules will also move from higher concentration to lower concentration cross cell membranes
