NEET Physics Degrees of Freedom MCQ Question
For a monoatomic ideal gas, what is the total translational kinetic energy per mole at temperature T, considering only translational degrees of freedom?
(3/2)RT
(5/2)RT
(1/2)RT
3RT
Correct Answer
Detailed Explanation
A monoatomic ideal gas has 3 translational degrees of freedom, and each degree of freedom contributes (1/2)k_B T to the energy per molecule. For a mole, it sums up to (3/2)RT.
