Step 1
What term is used for the spreading of the perfume molecules in this way?
Answer
The term used for the spreading of perfume molecules in the air is diffusion.
Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration, resulting in the even distribution of the substance throughout the available space. In this case, when the perfume bottle is opened, the perfume molecules move into the surrounding air, creating the scent that can be detected far from the source.
