Study Notes
Diffusion and Osmosis
- Diffusion is the random movement of molecules from an area of higher concentration to an area of lower concentration, resulting in uniform distribution.
- Osmosis is the movement of water molecules from an area of higher concentration to an area of lower concentration through a selectively permeable membrane.
- Diffusion and osmosis are related, as osmosis is a special case of diffusion that involves the movement of water molecules.
- Water concentration refers to the amount of dissolved substances in a solution, with a higher concentration indicating more dissolved substances and a lower concentration indicating fewer dissolved substances.
- Osmosis is considered a special case of diffusion because it involves the movement of water molecules only, whereas diffusion involves the movement of any molecule or ion.
