Which of the following is an example of a physical property?(1 point) Responses ability to burn ability to burn chemical composition chemical composition freezing point freezing point ability to react with metals
freezing point
Freezing point is an example of a physical property.
To determine which of the given options is an example of a physical property, we need to understand what a physical property is.
Physical properties are characteristics or attributes of a substance that can be observed or measured without changing its composition. These properties describe how a substance behaves under specific conditions. Common examples of physical properties include color, odor, density, melting point, boiling point, and ability to conduct electricity.
Now, let's analyze each option:
1. Ability to burn: This refers to a substance's combustibility, which is a chemical property rather than a physical property. Chemical properties describe how a substance interacts with other substances and undergoes chemical changes.
2. Chemical composition: This directly refers to the specific elements and compounds present in a substance, which falls under chemical properties.
3. Freezing point: This is a physical property that describes the temperature at which a substance undergoes a phase transition from a liquid to a solid state.
4. Ability to react with metals: This refers to the substance's chemical reactivity, which is a chemical property rather than a physical property.
Based on the explanations above, the correct answer is freezing point, as it is a physical property.
