Rules for Simple Diffusion [ Complete text in document posted under Assignments] 1. Diffusion is a ……. process that does not require an outside energy source. It uses only the kinetic energy of ……… ……… . 2. Molecules ……. from an area of higher concentration to an area of lower concentration. The …… the concentration difference, the …… diffusion takes place. 3. There will be … movement of molecules until the concentration is …. .. Molecular movement continues, however, so this is called a ………………. . 4. Diffusion is rapid over …. . distances but much slower over …. distances. 5. Diffusion is ……. . related to temperature.
