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)
What else can I help you with?
Is Pungent odor a physical or chemical change?
Pungent odor is a physical change because it only affects the sense of smell without altering the chemical composition of the substance emitting the odor.
Is odor is physical property?
Partly but it is also a chemical property.
Is heat light and change in odor indicate a physical change?
Heat, light, and change in odor can indicate a physical change depending on the context. For example, melting ice into water is a physical change because it does not alter the chemical composition of the substance. However, if a substance undergoes a chemical reaction that results in heat, light, and change in odor, then it would be considered a chemical change.
Is gasoline leaving an odor and drying a chemical or physical change?
Both
Is odor physical or chemical?
it is a chemical component which gives bad odor
Is a smelly sock a chemical or physical change?
A smelly sock is a chemical change because the release of odor is a result of chemical reactions occurring within the sock.
Is it true that Physical changes are often accompanied by changes in color or odor?
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).
Is a skunk producing odor physical or chemical change?
The skunk producing odor is a chemical change because it involves a reaction within the skunk's body that results in the release of specific compounds that create the distinctive smell. This process alters the chemical composition of the skunk's secretion, leading to the odor being produced.
Is gasoline that is dry but leaves an odor in a room a chemical change?
Yes, the gasoline evaporating and leaving an odor in a room is a physical change, not a chemical change. The gasoline is still the same substance, but in a different state (gas) and releasing volatile compounds that contribute to the smell.
Is pungent odor a chemical solution or physical?
Physical
When milk turns sour this is a physical change because a change in odor does not indicate a chemical change?
Actually, when milk turns sour, it is primarily a chemical change rather than a physical change. This occurs due to the fermentation process, where bacteria convert lactose (milk sugar) into lactic acid, resulting in a change in odor, taste, and texture. The formation of new substances, such as lactic acid, signifies a chemical change, as opposed to a mere alteration of physical properties.
Is odor physical property or chemical property?
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.
