Question

how can we smell perfume sitting several metres away from the source

Answer 1

The perfume molecules spread out or 'diffuse' through the air. The smell becomes less concentrated but it reaches a great distance - meaning you can smell it from relatively far away.

Answer 2

Hi friend, Here is the required answer:-
When a perfume is sprayed several metres away from the source, the particles of the perfume diffuses with the particles of the gas. As we know that the particles of the gas have more kinetic energy, therefore it gets diffused with perfume particles and gets moved very fastly and reaches us.
Hope this helps you...
