Diffusion and Osmosis Equilibrium
High Concentration Low Concentration
Diffusion Just like people, Molecules often want to avoid being crowded together. They move from areas of high concentration to areas of low concentration in a process called diffusion.
What’s the goal of diffusion? Molecules want to achieve equilibrium That means, they’d like to be evenly spread out.
Which of the following pictures shows equilibrium?

Osmosis Osmosis is simply a type of diffusion. It is when water moves from areas of HIGH concentration to areas of LOW concentration through a membrane. We have already witnessed osmosis in TWO of the experiments we’ve done this year. Can you name which two?
