| List-I | List-II | ||
|---|---|---|---|
| Alloys | Composition | ||
| (A) | Amalgam | (I) | Cu + Zn |
| (B) | Brass | (II) | Pb + Sn |
| (C) | Bronze | (III) | Cu + Sn |
| (D) | Solder | (IV) | Metal + Hg |
Choose the most appropriate answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → (A)-(IV), (B)-(I), (C)-(III), (D)-(II)
(A) Amalgam — this matches (IV) Metal + Hg. An amalgam is any alloy of mercury with another metal, such as the silver amalgam once used to fill teeth.
(B) Brass — this matches (I) Cu + Zn. Brass is copper with zinc, used for taps, fittings and musical instruments.
(C) Bronze — this matches (III) Cu + Sn. Bronze is copper with tin, harder than copper, used for statues, bells and medals.
(D) Solder — this matches (II) Pb + Sn. Solder is lead with tin; its low melting point makes it useful for joining wires and metal parts.
