Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Alkali metals are good conductors of heat and electricity.
Step 1: Why sodium is used.
• Low melting point
• High thermal conductivity
• Efficient heat transfer medium
Step 2: Application.
• Used as coolant in nuclear reactors
Step 3: Conclusion. \[ \text{Sodium is used for heat transfer} \]
