Question

define physical property | define chemical property

Explanation:

To define physical and chemical properties:

• Physical Property: A characteristic of a substance that can be observed or measured without changing the substance’s chemical identity (e.g., color, density, melting point).
• Chemical Property: A characteristic of a substance that describes its ability to undergo chemical reactions and form new substances (e.g., flammability, reactivity with acids).

Answer:

• Define Physical Property: A property of a substance that can be observed or measured without altering the substance’s chemical composition (e.g., color, density, boiling point).
• Define Chemical Property: A property of a substance that describes its ability to undergo chemical changes and form new substances (e.g., flammability, reactivity with oxygen).
