Question

The smell of perfume reaches till the considerable distance.why?

Answer 1

the smell of perfume reaches us at a considerable distance because the particles of the perfume diffuse and spread in the air

Answer 2

Because perfume is in gaseous state thats why the inter molecular space is large and intermolecular force of attraction is so weak that the molecules of perfume have great freedom of movement. The smell spreads all around (diffusing property ).The smell spreads because smell spreads because gas diffuses very fast.
