Answer:
Molecules always move from areas of high concentration to low concentration.
Explanation:
The correct answer to how diffusion works would be that molecules always move from areas of high concentration to low concentration.
Diffusion is generally defined as the movement of molecules - solid, liquid, or gases - from the region of higher concentration of the molecule to the region of lower concentration of the same molecule. The net movement of molecules continues until an equilibrium is established between the two sides.
