NEET Physics Degrees of Freedom Assertion Reason Question
Assertion (A): A molecule free to move in space has three degrees of freedom. | Reason (R): A molecule in thermal equilibrium at temperature T has an average energy value proportional to Boltzmann constant.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
A is true as a molecule in space can move in three directions. R is true because average energy is related to Boltzmann constant, but it does not explain A.
