Among liquids, water has a comparatively high value of thermal conductivity, due to its__________________?
Correct answer: C. Partial ionisation
- A. Low density
- B. High viscosity
- C. Partial ionisation
- D. Dense structure
Explanation
Water conducts heat relatively well among liquids because its polar molecules form a strongly connected, hydrogen-bonded structure; partial ionisation is the commonly cited textbook explanation among these options. Low density and high viscosity do not account for its comparatively high thermal conductivity.
