Give reason for the following observations.

We can get the smell of perfume sitting several metres away.

 

Answer

We can get the smell of perfume sitting several metres away due to diffusion.

Vapours of perfume move rapidly in all directions and spread in the air by diffusion. When perfume vapours reach several metres away we can get the smell of perfume.

Droplets of perfume diffuse into the air enabling us to smell from several metres away-Teachoo.jpg
