As it is pressed out of the bottle, its kinetic energy is also increased so it quickly diffuses in the surroundings reaching many meters away. read less

It is basically due to the phenomenon known as Diffusion wherein the particles get transmitted from one place to other.

When perfume is released from the bottle it quickly changes into vapor. The perfume vapor moves rapidly in all the directions as it is volatile. The kinetic energy of the gas molecules is high and the rate of diffusion is high .Hence, we can get the smell of perfume sitting several meters away. Smell is a very direct sense. In order for you to smell something like perfume, molecules from that thing have to make it to your nose. Everything you smell, therefore, is giving off molecules -- whether it is perfume, bread in the bakery, onions, a piece of fruit or whatever. Those molecules are generally light, volatile (easy to evaporate) chemicals that float through the air into your nose. A piece of steel has no smell because nothing evaporates from it -- steel is a non-volatile solid. At the top of your nasal passages behind your nose, there is a patch of special neurons about the size of a postage stamp. These neurons are unique in that they are out in the open where they can come into contact with the air. They have hair-like projections called cilia that increase their surface area. An odor molecule binds to these cilia to trigger the neuron and cause you to perceive a smell. read less

The particle of perfume moves from its place higher concentrations to the place of lower concentrations by the process of diffusion.
