Question

Match List I with List II.

• A. A-III, B-I, C-IV, D-II
• B. A-I, B-II, C-IV, D-III
• C. A-IV, B-I, C-II, D-III
• D. A-II, B-III, C-I, D-IV

Hint:

Logic Tip: Lead has the lowest melting point, while copper melts at the highest temperature among these metals.

Answer 1

The Correct Option is A

Concept:
Different metals melt at different temperatures. Knowledge of melting temperatures is important in:
• Metal casting
• Bronze sculpture
• Industrial foundry work

Step 1:
Aluminium melts around: \[ 630^{\circ}C \] Thus: \[ A \rightarrow III \]

Step 2:
Copper melts around: \[ 970^{\circ}C \] Thus: \[ B \rightarrow I \]

Step 3:
Silver melts around: \[ 880^{\circ}C \] Thus: \[ C \rightarrow IV \]

Step 4:
Lead melts around: \[ 280^{\circ}C \] Thus: \[ D \rightarrow II \] Therefore, the correct matching is: \[ A-III,\; B-I,\; C-IV,\; D-II \] Hence, the correct answer is: \[ \boxed{\text{(1) A-III, B-I, C-IV, D-II}} \]
