According to the kinetic theory, the thermal conductivity of a monatomic gas is proportional to___________________?
Correct answer: B. T0.5
- A. T
- B. T0.5
- C. T1.5
- D. T2
Explanation
Kinetic theory gives gas molecules an average speed proportional to the square root of absolute temperature. With other collision properties treated as constant, thermal conductivity therefore varies as T^0.5, not T or T^1.5.
