Question

Quizplus · Accepted Answer

Diffusion is a passive process that depends on the random motion of molecules. They move from an area of higher concentration to an area of lower concentration until the concentration becomes balanced. This process does not involve active forces, and its rate increases as the temperature increases, not decreases. The chemical gradient of a substance affects the direction and rate of diffusion.
