Which of the following is not an example of a physical property of a substance?
density
combustion
solubility
freezing point
thx
Combustion is not a property but a chemical reaction.
To determine which of the following is not an example of a physical property of a substance, let's first understand what physical properties are. Physical properties describe the characteristics of a substance that can be observed or measured without changing the substance's chemical composition.
Now, let's examine each option and identify whether it is a physical property or not:
1. Density: Density is a physical property that describes the mass of a substance per unit volume.
2. Combustion: Combustion is not a physical property; it is a chemical property. Chemical properties are observed when a substance undergoes a chemical change or reaction. Combustion involves the reaction of a substance with oxygen, resulting in the release of heat and light.
3. Solubility: Solubility is a physical property that describes the ability of a substance to dissolve in a particular solvent, forming a homogeneous mixture.
4. Freezing Point: Freezing point is a physical property that indicates the temperature at which a substance changes from a liquid to a solid state.
Based on the explanations above, the answer is:
The example that is not an example of a physical property of a substance is "combustion."
