First, some background top top properties.

There space two general categories ofproperties that are offered to define materials:chemical properties and also physical properties.

You are watching: Is odor a physical or chemical property

Chemical properties describe chemical alters ofmatter, i.e. Changes that result in alters tocomposition the matter. Some examples areflammability, acidity, and also oxidationbehavior. Incontrast physical properties are characteristicsthat deserve to be measured without transforming the chemicalcomposition of the matter. These include mass,length/shape measurements, and phasetransformation temperature (e.g. Boiling andmelting points). Next, consider what "makes" an odor .

Basically, molecules of the issue in the airdissolve into mucus and eventually tie with(physically to the right into) smell receptors. All ofthese space physical alters though; no one arerelated to a change in composition. Thus, odor isnot a chemistry property, yet rather is a physicalproperty. that being said, a new odorbeingdetected have the right to be one indication that a chemical change whichresulted inthe formation of a new substance (one through adifferent connected odor).

nodiscussion the the differences in between chemical andphysical properties or that odors.

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

Answer 2:

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

Answer 3:

Not yes, really - odor is something the your sensesare able come detect. Different animals smelldifferent chemicals, and also are an ext or lesssensitive to different chemicals. What chemicalsare odiferous also varies within varieties - whatyou smell may not be the same as what somebodyelse smells.

Answer 4:

No, odor is a physical property. Ingeneral, properties of materials are divide aschemical or physical. physics propertiesare identified without transforming the identification ofthe substance. That way that there is nochange to the atom or molecular structure of thesubstance. Chemical properties are the opposite- they execute involve adjust to the molecular oratomic framework of the substance.

Broadly,this way that chemical properties have to dowith chemical reactions, and also physical propertiesdo not. You smell an odor once molecules that thesubstance get in your nose and also bind withreceptors (that means they fit into andthen stick to the receptors, like how two Legoblocks stick together) in your nose, which thenrelay a blog post to your brain which that interpretsas a “smell.”

Since we smell points without causing anychange to the molecular framework of thesubstance, smell is classified together a physicalproperty. Keep in mind that chemistry reactions take placein our body so that the receptor can communicatewith our brain, however there is no chemicalreaction come the molecule that the problem itself.
