liquid to gas formation is physical change
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.
Gasoline has a strong, pungent smell that is often described as sharp or chemical-like. This distinct odor is due to the presence of volatile organic compounds in gasoline, such as benzene and toluene. These compounds evaporate easily at room temperature, releasing vapors that create the characteristic smell of gasoline. The human nose is sensitive to these compounds, which is why gasoline has a noticeable and recognizable odor.
Odor is a physical property because it can be observed and measured without changing the chemical composition of the substance. It is a sensory perception that is detected through the sense of smell.

The color of gasoline, whether clear or pink, is a physical property. Physical properties are characteristics that can be observed or measured without changing the substance's chemical composition. In the case of gasoline, its color can vary due to the presence of additives or impurities, but this does not alter the fundamental chemical structure of the substance.
Odor is a chemical property.
No it is a chemical property
Gasoline burning is a chemical property because it involves a chemical reaction where gasoline is combined with oxygen to produce heat, light, and exhaust gases. This process results in a change in the chemical composition of the gasoline.
No, it is a chemical property
Partly but it is also a chemical property.
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.

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.
Yes, a chemical property of gasoline is its flammability, which means it can easily ignite and burn in the presence of an oxidizer like oxygen. When gasoline burns, it undergoes a chemical reaction known as combustion, producing heat, light, carbon dioxide, and water vapor. This property is what makes gasoline a suitable fuel for engines and other combustion processes.
