With increase in temperature, the thermal conductivity of a gas ___________________?
Correct answer: A. Increases
- A. Increases
- B. Decreases
- C. Remain same
- D. May increase or decrease depending on the type of gas
Explanation
Gas molecules move faster at higher temperature, increasing the transport of molecular energy and hence thermal conductivity. This trend is typical of gases, unlike many liquids whose conductivity decreases with temperature.
