away.​

Answer 1

Answer:

We can get the smell of perfume sitting several metres away because perfume contain volatile solvent which vaporises very fast and its vapours diffuse faster into air. As a result the smell of perfume can reach people sitting several metres away.

Answer 2

Answer:

When perfume is released it quickly changes into vapour. The kinetic energy of gas molecules is high & the rate of diffusion is high. Hence we can smell the perfume sitting several metres away.
