Which is not a physical property?
Correct answer: D. Reactivity with oxygen
- A. Odour
- B. Phase
- C. Boiling point
- D. Reactivity with oxygen
Explanation
Physical properties are characteristics of a substance that can be observed or measured without any change in the chemical composition of the substance. 'Reactivity with oxygen' is the correct option as it describes a chemical behavior, which is a chemical property, not a physical property. The other options - 'Odour', 'Phase', and 'Boiling point' are all physical properties as they relate to inherent characteristics of a substance.
