iGCSE Chemistry Multiple Choice (Extended) : 9.2 Uses of metals: Exam Style Questions Paper 2

iGCSE Chemistry MCQ (Extended) Paper 2 - All Chapters
Question

Which row gives a use for the named metal and two properties which both explain this use?

 metaluseproperty 1property 2
Aaluminiumaircraft constructionhigh densityresistant to corrosion
Bcopperelectrical wiringgood electrical conductivityductile
Caluminiumfood containersresistant to corrosionnot malleable
Dcopperaircraft constructionmalleablelow density
▶️ Answer/Explanation
Solution

Ans: B

Let’s evaluate each option:

A: Incorrect – Aluminium is used in aircraft but because of its low density, not high density

B: Correct – Copper is ideal for wiring because:

  • Excellent conductivity (essential for wiring)
  • Ductility (can be drawn into thin wires)

C: Incorrect – Aluminium is malleable (can be shaped into containers)

D: Incorrect – Copper isn’t used in aircraft (too dense) and doesn’t have low density

Only option B correctly matches the metal, its use, and two relevant properties.

Question

 Which statements about the uses of metals are correct?

1 Iron is used to make aircraft because iron has a low density.
2 Copper is used to make electric cables because copper is a good conductor of electricity.
3 Aluminium is used to make brass because aluminium is strong and hard.
4 Iron is mixed with additives to make an alloy used in chemical plant.
A 1 and 2 B 3 and 4 C 1 and 3 D 2 and 4

Answer/Explanation

Ans: D
