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

creamy, vinegar odor
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]
It's a physical property, because physical properties are color, smell, freezing point, boiling point, melting point, apprearance, or repulsion (diamagnetic) to magnets, opacity, viscosity and density.
Physical
It would be a physical change because it is not changing the chemical composition.
Due to the pungent odor of the chemical, the classroom was cleared.
Acetic acid (vinegar), ammonia, acetone (nail polish remover), rubbing alcohol, and garlic all have pungent odors.
it is a chemical component which gives bad odor
Spearmint's distinctive aroma is attributed to one of the volatile oils, the chemical carvone.
it is a physical change because no reaction occurs and there is no new substance. :)
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)
Solid nonmetal with a very pungent odor and can be poisonous. It does not melt, but undergoes sublimation.
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.
Color and density are physical properties. Odor and solubility are chemical properties.
