We can get the smell of perfume sitting several metres away due to diffusion. Vapours of perfume move rapidly in all directions and spread in the air by diffusion.
The perfume molecules spread out or 'diffuse' through the air. The smell becomes less concentrated but it reaches a great distance - meaning we can smell it sitting several metres away from the source.
