First, some background top top properties.

There are two general categories ofproperties the are supplied to define materials:chemical properties and also physical properties.

You are watching: Is odor a physical or chemical property

Chemical properties define chemical transforms ofmatter, i.e. Transforms that result in changes tocomposition of matter. Some examples areflammability, acidity, and oxidationbehavior. Incontrast physical properties are characteristicsthat have the right to be measured without transforming the chemicalcomposition that the matter. These encompass mass,length/shape measurements, and phasetransformation temperatures (e.g. Cook andmelting points). Next, take into consideration what "makes" an smell .

Basically, molecule of the matter in the airdissolve into mucus and also eventually tie with(physically to the right into) smell receptors. All ofthese space physical transforms though; nobody arerelated to a adjust in composition. Thus, odor isnot a chemistry property, but rather is a physicalproperty. that being said, a new odorbeingdetected deserve to be an indication of a chemical readjust whichresulted inthe formation of a new substance (one with adifferent linked odor).

nodiscussion the the differences between chemical andphysical nature or that odors.

These answers give an ext background top top odors, butnot chemistry vs. Physical properties.>

Answer 2:

When i was one undergrad, my professor got achemical produced for his research. Thebottle stated it had actually "no physiological effects," butit smelled prefer popcorn. The professor said"odor" to be a physiological effect.

Answer 3:

Not yes, really - odor is something the your sensesare able to detect. Different pets smelldifferent chemicals, and also are much more or lesssensitive to various chemicals. What chemicalsare odiferous even varies within types - whatyou smell may not it is in the exact same as what somebodyelse smells.

Answer 4:

No, smell is a physics property. Ingeneral, nature of products are share aschemical or physical. physical propertiesare figured out without transforming the identification ofthe substance. That method that over there is nochange come the atom or molecular structure of thesubstance. Chemical properties space the opposite- they carry out involve readjust to the molecule oratomic structure of the substance.

Broadly,this means that chemical properties need to dowith chemical reactions, and also physical propertiesdo not. You odor an odor when molecules that thesubstance go into your nose and also bind withreceptors (that method they fit right into andthen stick to the receptors, like exactly how two Legoblocks stick together) in her nose, which thenrelay a article to your mind which that interpretsas a “smell.”

Since us smell things without bring about anychange to the molecular framework of thesubstance, odor is classified together a physicalproperty. Keep in mind that chemistry reactions take placein our body so that the receptor have the right to communicatewith our brain, yet there is no chemicalreaction to the molecule of the problem itself.
