Question

we can get the smell of perfume sitting several metres away​

Answer 1

Answer:

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.

When a perfume is sprayed several metres away from the source, the particles of the perfume diffuses with the particles of the gas

Answer 2

this happens because gases have the maximum amount of kinetic energy in them...

Which means the particles of has are moving continuously on the highest state.

so when someone applies perfume on its body or clothes the vapours of the perfume move continuously at the highest state and get in ur nostrils.
