That describes a chemical property.
A chemical property can only be observed when a substance undergoes a chemical change (reacts with another substance) — e.g., gasoline burning or sodium reacting with water. Contrast: a physical property can be observed without changing the substance’s identity (mass, density, melting point, color, etc.).
Common signs of a chemical change: gas evolution, color change, precipitate formation, temperature or light release, and permanent odor change.
