What does a chemical property NOT typically include?

Chemical properties are characteristics that can only be observed during a chemical reaction and involve changes in the substance's composition. Examples of chemical properties include reactivity with acids, flammability, and other behaviors that indicate how a substance interacts chemically with other substances or conditions.

The physical state at room temperature, such as whether a substance is solid, liquid, or gas, falls under physical properties. These are traits that can be observed without changing the chemical identity of the substance, such as melting point, boiling point, and color. While the physical state may influence how a substance reacts, it does not describe the substance's inherent chemical behavior.

This distinction highlights why the physical state at room temperature is not considered a chemical property, making it the correct answer to this question.
