- Diffusion is where the particles spread out from an area of high concentration into an area of low concentration
- Diffusion happens when different types of gases diffuse through each other.
- It also happens in cell membranes.
- This is where gas particles spread out
- dissolved substances move in and out of cells using diffusion
- The cell membranes help this as they let a lot of things in or out
