NEET Physics Degrees of Freedom MCQ Question
Which of the following statements about the degrees of freedom in molecular motion is correct?
A molecule in three-dimensional space possesses three degrees of freedom for translation.
A molecule constrained to move in a plane has three degrees of freedom for translation.
A molecule that can only move along a line has two degrees of freedom for motion.
Degrees of freedom are defined only for translational motion, not for rotational or vibrational motion.
Correct Answer
Detailed Explanation
A molecule in three-dimensional space indeed possesses three degrees of freedom for translation, as indicated in the context. The other options misrepresent the degrees of freedom associated with constrained motion.
