With increase in temperature, the thermal conductivity of most liquids_________________?
Correct answer: B. Decreases
- A. Increases
- B. Decreases
- C. Remain same
- D. First increases upto a certain temperature and then becomes constant
Explanation
The thermal conductivity of most common liquids decreases as temperature rises, although a few liquids show exceptional behaviour over particular ranges. Hence the usual engineering trend is option b.
