NEET Physics Degrees of Freedom MCQ Question
For a diatomic gas molecule at thermal equilibrium at temperature T, what is the total average translational kinetic energy per molecule?
3/2 k_B T
5/2 k_B T
k_B T
2/3 k_B T
Correct Answer
Detailed Explanation
The degrees of freedom for translational motion in three-dimensional space is 3, leading to an average energy of 3/2 k_B T per molecule as stated in the NCERT context.
