You can smell the perfume sitting several meters away why?

Answer 1

Perfumes contain volatile vapors of sweet-smelling compounds that diffuse in air when the bottle is opened. Gaseous molecules move at several hundred meters per second, and so smells can travel quickly across a room.

Answer 2

Perfume particles are volatile and can easily travel through the air. Even at a distance, the odor molecules can disperse and reach your nose, allowing you to detect the scent. The strength and type of perfume, as well as air circulation, can influence how far the scent travels.

Answer 3

The perfume evaporates, and its molecules enter the air to be detected as smells. By the process called diffusion, the molecules spread to the air in other parts of the room (generally from an area of higher concentration to lower).

Perfume scents are among the most easily detected, with as little as a few parts per million in the air.

Answer 4

There are a couple of things at work here, drafts and breezes aside. One is that the perfume is volatile. The perfume is designed with ingredients that give it a pleasant and attractive aroma, but also some that cause it to evaporate and leave the skin or whatever it is on. The now airborne molecules travel around via the process of diffusion, and that's how they get to you so you can detect them, even though you may be some distance off in an environment where the air is still.

because the molecules move freely and quickly .there is no force restrict the motion of the molecules in gases.

Answer 5

Molecules in the air are bouncing around and moving very fast. When you speak, you are causing movements in the air particles. This means that particles in the air are moving close to the speed of sound. So when you smell perfume from several meters away, its because those organic molecules have traveled far enough to find your nose.

The process is called simple diffusion, and it is the movement of molecules from a high concentration to a low concentration, until equilibrium is reached. The can be through a medium of air or water.

Answer 6

All smells are particulate, which means that there are small particles of the perfume that evaporate and gets carried by the air from the source to your nose.

Answer 7

Perfume is volatile substance and gas has more intermolecular spaces so when we use perfume its particle spread several meters away and we can smell it

Answer 8

because when the bottle opened the particles present in it mixed with air and travels other end of the room.

Answer 9

The perfume molecules evaporate and diffuse in the atmosphere. Your nose detects these molecules.

Answer 10

because of diffusion
