Quizplus · Accepted Answer

The movement of perfume molecules from the spilled bottle to the air and then to the far side of the lecture hall is an example of simple diffusion. The molecules move from an area of high concentration (near the bottle) to an area of low concentration (farther away from the bottle) until the concentration is equalized in the room. Osmosis, facilitated diffusion, and active transport are not applicable to this scenario.
