Answer:
The statement, "The smell of perfume spreads due to the evaporation of perfume into air" is incorrect.
Explanation:
The smell of perfume spreads due to the process of diffusion and not because of evaporation, as mentioned in the statement. Evaporation refers to the process due to which a liquid changes into its gaseous state. Diffusion refers to the net movement of particles from an area of low concentration to an area of high concentration. So, the statement is wrong. It should have rather been, "The smell of perfume spreads due to the diffusion of perfume into air".
