Which of the following is an example of a physical property?(1 point) Responses ability to burn ability to burn freezing point freezing point chemical composition chemical composition ability to react with metals
freezing point
The freezing point is an example of a physical property.
To determine which of the options is an example of a physical property, we need to understand what a physical property is.
A physical property is a characteristic of a substance that can be observed or measured without changing the composition of the substance. It does not involve any chemical reactions.
Now let's examine each option:
1. Ability to burn: Burning is a chemical reaction, not a physical property. Therefore, this option does not represent a physical property.
2. Freezing point: This is an example of a physical property. Freezing point is the temperature at which a substance changes from a liquid to a solid state without undergoing any chemical changes.
3. Chemical composition: Chemical composition refers to the types and amounts of elements and compounds that make up a substance. It is not a physical property as it involves the composition of the substance which requires a chemical analysis.
4. Ability to react with metals: Reactivity with metals is a chemical property, not a physical property. It describes the ability of a substance to undergo a chemical reaction with metals.
Based on the explanations provided, the option that represents a physical property is freezing point.
