Question
- A. It increases the melting point.
- B. It improves electrical conductivity.
- C. It enhances strength and corrosion resistance.
- D. It makes the metal more brittle.
Answer
The correct option is It enhances strength and corrosion resistance.. This answer is correct because it matches the approved learning objective to recall bronze as an alloy of copper and tin. (Chemistry only) in the subtopic Alloys as useful materials.
Explanation
The correct option is It enhances strength and corrosion resistance.. It enhances strength and corrosion resistance. is correct because it directly supports the approved learning objective to recall bronze as an alloy of copper and tin. (Chemistry only). This belongs to the subtopic Alloys as useful materials within Using materials, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Alloys as useful materials.
Common mistake
Confusing Bronze Composition
Students often incorrectly state that bronze is an alloy of copper and zinc.
Remember that bronze is specifically an alloy of copper and tin, not zinc.
