What else can I help you with?
What sensory evidence could be used to argue that a chemical transformation of the substance had occurred?
by a change in smell and appearence of a substance
Is smell a physical or chemical property?
Your SENSE of smell is physical, but smells are created by chemical interactions.
Does smell change with a physical change?
Smell is a physical property. It it caused by small amounts of the airborne substance undergoing chemical reactions with receptors in your nose.The smell of perfume is a physical not a chemical
What chemical property of a substance and is detected by the sense of smell?
The chemical property of a substance detected by the sense of smell is its volatility, which determines how easily molecules of the substance can become airborne and reach olfactory receptors in the nose. Substances with higher volatility are more likely to produce a detectable scent.
Is the smell of vinegar a chemical property?
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.
How are the senses and taste and smell similar?
Both the sense of taste and the sense of smell detect the chemical composition of a substance through chemoreceptors.Taste is detected by the tongue in solids and in liquids, while smell is detected by the nose in airborn substances.
How the senses of smell and taste are similar?

Is oder a physical or chemical property?
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.
What is the chemical formula for ammonium hydroxide substance?
Ammonium hydroxide's chemical formula is NH4OH. This is the primary ingredient in household ammonia, which is a cleaning agent. It has a characteristically awful smell.
Is decaying matter a physical or chemical change?
It's a chemical change. A chemical change is any change that causes a substance to change into another substance. A sign to know whether it's a chemical change or not, are the changes in odor. When something decays the change in smell is very powerful. Therefore, it is a chemical change.
What do cfc smell off?
CFCs (chlorofluorocarbons) are odorless, colorless gases at room temperature and cannot be detected by smell. The odor of a substance depends on its chemical properties, but since CFCs are inert and have low reactivity, they do not produce a distinct smell.
What is the relationship between the chemical property of a substance and the chemical changes of a substance?
The chemical properties of an object show what a chemical change did to that substance.
