Question

Give reason for the following observation
(b) We can get the smell of perfume sitting several metres
away.​

Answer 1

Explanation:

Perfume has a higher degree of vaporization, and its vapour diffuses into the air easily. Gaseous particles possess high speed and move very rapidly in all directions. When perfume is sprayed, its particles diffuse into the air particles at a high-speed rate and reach our nostrils. This enables us to smell the perfume from a distance.
