Imagine you sprayed perfume in the corner of a room. Based on the passage, what is the concentration of perfume particles like in that corner, compared to the rest of the room?
Understand the Problem
The question is asking about the concentration of perfume particles in a corner of a room compared to the rest of the room after spraying perfume. It requires an understanding of the diffusion of particles in a space.

The final answer is D. That corner has a higher concentration of perfume particles than the other corners of the room.
Answer for screen readers
The final answer is D. That corner has a higher concentration of perfume particles than the other corners of the room.
More Information
When you first spray perfume, the particles are densely packed in the area where the spray occurs. Particle diffusion gradually equalizes the concentration over time.
Tips
A common mistake is assuming that the concentration is uniform immediately after spraying, but initially it is highest where sprayed.
