Aperfume bottle is dropped in the corner of a room. the odor of the perfume can be detected on the other side of the room. which statement best describes this observation?

particles are moving from regions of high concentration to low concentration. particles are moving from regions of low concentration to high concentration. particles are moving through a small opening into a smaller volume. particles are moving through a small opening into a larger volume.

The question is giving us the following scenario: "A perfume bottle is dropped in the corner of a room. The odor of the perfume can be detected on the other side of the room" I am assuming here that the bottle broke, so there is no opening that is relevant. but even if it didn't break, smells usually travel through diffusion from regions of high concentration to low concentration. - so the best answer is: Particles are moving from regions of high concentration to low concentration. At the end, equal concentration in the whole room is to be expected.
