Chapter 17, Problem 36A

To determine

To Explain: One can smell of shaving lotion immediately after man who was wearing the lotion enters the room, from the atomic point of view.

Explanation of Solution

Diffusion is the process where molecules or atoms can spread throughout the medium from higher concentration to lower concentration. Here, the process is driven by the concentration gradient.

On the surface of his face, the lotion molecules are in a high concentration and they are continuously spreading throughout the room by diffusion via the air inside the room and when the molecules move through the air, nose can detect its presence.

Conclusion:

Molecules of the lotion are spread throughout the air inside the room by diffusion process and nose can detect its presence.
