Which type of property is ductility classified as?

• A. Extensive property
• B. Intensive property
• C. Chemical property
• D. Physical property

Answer: (D)

Verified step by step guidance

1. Understand the difference between extensive and intensive properties: Extensive properties depend on the amount of substance (e.g., mass, volume), while intensive properties do not depend on the amount (e.g., density, melting point).
2. Recognize that chemical properties describe a substance's ability to undergo chemical changes (e.g., flammability, reactivity), whereas physical properties can be observed or measured without changing the substance's identity.
3. Recall that ductility is the ability of a material to be stretched into a wire without breaking, which is a characteristic related to the physical behavior of the material.
4. Since ductility does not depend on the amount of material and does not involve a chemical change, classify it as an intensive physical property.
5. Conclude that ductility is best classified as a physical property, specifically an intensive physical property.
