Thermal conductivities of most of the liquids _______________ with rise in temperature?
Correct answer: B. Decreases
- A. Increases
- B. Decreases
- C. Remains unchanged
- D. May increase or decrease; depends on the liquid
Explanation
For most liquids, increasing temperature weakens intermolecular interactions and reduces thermal conductivity. Water and a few special liquids can show unusual behaviour over limited ranges, but the general trend is a decrease.
