Question

Match the LIST-I with LIST-II

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

Hint:

Copper has very high melting point compared to mercury.

Answer 1

The Correct Option is D

Concept:
Different substances possess characteristic melting points.
Step 1:
Hydrogen has very low melting point: \[ 14~K \] \[ A \rightarrow IV \]
Step 2:
Mercury melts at: \[ 234~K \] \[ B \rightarrow III \]
Step 3:
Lead melts at: \[ 601~K \] \[ C \rightarrow II \] Copper melts at: \[ 1356~K \] \[ D \rightarrow I \]
Step 4:
\[ A-IV,\quad B-III,\quad C-II,\quad D-I \] \[ \boxed{\text{Correct Option = (4)}} \]
