Which term describes the property that may describe flammability or reactivity?

• A. Chemical property
• B. Physical property
• C. Physical change
• D. Chemical change

Answer: (A)

Flammability and reactivity describe how a substance behaves in chemical reactions. That kind of behavior is a chemical property, because it tells you how the material can change into new substances when it interacts with fire or other reactants. In contrast, physical properties—like color, hardness, or melting point—are attributes you can observe without changing the material’s identity, and physical changes, like ice melting, alter form but not what the substance actually is. Chemical changes are the actual transformations that create new substances. So, the best term for describing those traits is chemical property.
