A smell is created when a substance releases molecules (particles) into the air. ... Smells travel through the air by a process called diffusion; air particles, and the odour particles within the air, move freely in all directions. They are constantly moving and eventually they spread out through the air around them.

The smell of any substance example perfume is the gaseous form of that substance which our olfactory system can detect even at very low concentrations. Hence, the smell is not considered as a matter.

Yes, but as soon as the smell travels, it's not vacuum anymore. Smells are gas detected by nose. Gas can travel by a process called Diffusion. Simply said, your gas molecules will "try" to be evenly distributed in you medium.

Zero Odor works differently than other odor-removing products. It doesn't contain any enzymes. It works through a chemical-bonding process in which Zero Odor molecules attach themselves to ALL odor molecules, rendering them harmless and odorless. This is a quick and irreversible reaction.

The most common material is clay, although recycled paper "pellets" and silica-based "crystal" variants are also used. Sometimes, when an owner wishes to stimulate the cat's natural instincts, natural dirt is used. The cat-box that the litter is poured into can give off a strong odor, if not disposed of properly.

Answer: Ionic compounds have very strong forces holding them together, so the molecules wouldn't easily "break off" and float in the air, which is what you're smelling when you smell perfume.

What they're really smelling is ozone. In fact, the word ozone is derived from the Greek verb ozein, which means “smell.” This is particularly fitting given the strong aroma of this chemical compound. Ozone has a distinctive smell that humans can detect even in small concentrations — as few as 10 parts per billion.

Tiny amounts of hydrogen, carbon dioxide, and methane combine with hydrogen sulfide (say: SUHL-fyde) and ammonia (say: uh-MOW-nyuh) in the large intestine to give gas its smell. Phew!

Air was considered a “pure” element, but in fact the air that's all around us is made up of a variety of gases: primarily nitrogen and oxygen, with almost 1% argon and even smaller amounts of carbon dioxide and other elements such as krypton and helium. The composition of air is just right for life on Earth, though.

Particles can be atoms, molecules or ions. Atoms are single neutral particles. Molecules are neutral particles made of two or more atoms bonded together.

A new study suggests that sickness does actually have a unique odor — that of the overactive immune system. And other humans can actually smell when someone is fighting off an infection.
