Only the fourth statement is correct.
Quick breakdown:
- "Include changes of state of a substance." — False. Changes of state (melting, boiling, condensation) are physical changes/properties.
- "Can be observed without altering the identity of the substance." — False. That describes physical properties; observing a chemical property usually requires a chemical change (the substance's identity changes).
- "Include mass and color" — False. Mass and color are physical properties.
- "Include changes that alter the identity of the substance." — True. Chemical properties describe how a substance reacts or transforms (e.g., flammability, reactivity with acids, oxidation), and observing them involves chemical change.
