Odor results from chemical reactions. Sensors in your nostrils bind with specific compounds in the air to detect scents. But this is not to be confused with the fact that odor is a physical property.
Odour is a chemical property and is entirely dependent on the chemical structure of the molecules of a substance.
Added:
Odor is by many considered as chemical interaction with nasal odor receptors, though this is still under dispute.
I, personally, would be more of the 'physical' odor perception, because the odor-creating molecules (eg. in perfume) do not change at all while being 'percepted' in your nose.
However there are also undoubtly pure chemical odor perceptions, like those of (gaseous) 'acids', 'ammonia', 'formalin' and hydrogen sulfide.

yes ............... paint bubbling is a chemical reaction. when anything bubbles you know there is a chemical reaction.
Those have nothing to do with each other. Smelling is something your body does to take in orders, and a chemical reaction is a reaction that cannot be reversed. Thus, smelling does not have anything to do with a chemical reaction.
chemical
Physical changes give no evidence that a chemical reaction has taken place, because no chemical reaction has taken place.
it is a chemical component which gives bad odor
AnswerNeither. Odor is not a change at all. Odor is airborne molecules that have a particular smell. A change is a process and odor is not a process. The things which cause odors can be either physical or chemical. For instance, the body odor is caused by chemical changes, but if you open jar of a smelly chemical, that is a physical change (some of the molecules of the chemical are evaporating and are thus airborne).When talking about mixing chemicals and substances, a change in odor is a chemical change.(I assume this is what you meant when you asked is odor a chemical or physical change)

Color and density are physical properties. Odor and solubility are chemical properties.

Luster is a physical property or reaction.
This is a chemical reaction.
Physical reaction.
It would be a physical change because it is not changing the chemical composition.
Its a chemical reaction.
