Question

a perfume bottle is dropped in the corner of a room and it shattered. 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.

Explanation:

This observation demonstrates diffusion, where particles (perfume molecules) spread out from an area of high concentration (near the shattered bottle) to an area of low concentration (the other side of the room) until they are evenly distributed. The other options do not match this fundamental process.

Answer:

A. Particles are moving from regions of high concentration to low concentration.
