Question

How can we smell perfume sitting several metres away from the source?

Answer 1

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

Perfume is a volatile liquid. When liquid perfume is applied by a person is quickly changes into vapours or gas. The Perfume vapours move very rapidly in all directions in air, a mix up with air particles and spread in the air by diffusion. When this air containing perfume Vapours reaches several metres away, we can smell the perfume.

Answer 2

ANSWER:-

When perfume is released from the bottle it quickly changes into vapour. The perfume vapour moves rapidly in all the directions as it is volatile. The kinetic energy of the gas molecules is high and the rate of diffusion is high. Hence, we can get the smell of perfume sitting several meters away.
