Which of the following liquid metals has the highest thermal conductivity ?
Correct answer: A. Molten sodium
- A. Molten sodium
- B. Molten lead
- C. Mercury
- D. Molten potassium
Explanation
Among the listed liquid metals, molten sodium has the highest thermal conductivity, making it effective for high-temperature heat transfer. Mercury, lead, and potassium conduct heat less effectively under comparable liquid conditions.
