The strong, sweet smell of perfume reaches your nose so quickly because the chemicals in the perfume evaporate easily in the air so that we can smell them. In addition, the chemical itself can be smelt.
when the particles flow to the air they come straight to your nose
Diffusion
Because your nose is clogged, so particles used by the nose to detect smell are no receiving the particles because mucus is blocking the way.
Gase particals
almost every thing produce odour particles but the human nose does not detect every smell
We smell because of particles in the air. Air currents , due to people moving about or fans in the room. carry the particles across the room and the nerves in your nose detect them.
All smell are just molecules. The gradually desperse into small particles that your nose adjusts or you just can smell it anymore.
Febreze cleans the air by using tiny droplets of a sprayed mist. These attach themselves to dust and smell particles in the air and so the nose can no longer smell the 'bad' smell
Odors effect sensitive membranes in your nose. Each odor has a unique effect on your nose and your body absorbs the essence of the odor through particulates caught in your nose. When you smell, for instance, a clogged toilet your nose is catching small particles floating in the air around the source. The body creates saliva and some mucous to flush out some of the particles, dulling the sense briefly and reducing the odor. It's sort of your nose's gag reflex.
Smells are actually particles that are airborne. The reason you can smell things from other rooms for example is because of the air curculation and movement in your house (hot air rises) which is carrying small particles, which you inhale through your nose.
yes smoke has mass. smoke is made of little particles of whatever is being burned. that's why you can smell smoke, because the little particles react with receptors in your nose.
If you polish a piece of aluminium with a cloth you can smell the metal. this is because particles from the aluminium have gone into the air. i don't know if this is the proper answer, but i think it is a reason.
The particles stick to the receptors of the cilia in the nose.
Small particles of the scented material diffuse through the air. (E.g spraying an aerosol will result in the particles diffusing quite quickly) Then, as a person inhales through their nose, some of the scented particles will be inhaled, hitting the olfactory membranes, making us "smell" something.
