It would be a physical change because it is not changing the chemical composition.

Partly but it is also a chemical property.
A smelly sock is a chemical change because the release of odor is a result of chemical reactions occurring within the sock.
No, a chemical change is usually accompanied by a change in color or odor. A physical change is a change that is the same substance before and after and usually accompanied by a change in state of matter (evaporation, condensation, melting, freezing, sublimating, etc).
it is a physical change because no reaction occurs and there is no new substance. :)
Odor is a chemical property.

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)
Due to the pungent odor of the chemical, the classroom was cleared.

Both
it is a chemical component which gives bad odor

No. Change in odour is likely to be related to a chemical process.
its physicalAdded: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.[I would indeed call those pungent odors]
