Question

Quizplus · Accepted Answer

Diffusion is the process by which particles move from an area of high concentration to an area of low concentration. In this scenario, the perfume molecules are diffusing from an area of high concentration (inside the bottle) to an area of low concentration (surrounding air), resulting in the scent being detected by someone many feet away.
