Translational kinetic energy of molecules of an ideal gas is proportional to (where, T = absolute temperature of the gas)__________________?
Correct answer: B. T
- A. √T
- B. T
- C. T2
- D. 1/√T
Explanation
The average translational kinetic energy of ideal-gas molecules is proportional to absolute temperature, as given by the molecular relation 9 mv = 9 kT per molecule. Hence it varies directly as T.
