NEET Physics Degrees of Freedom MCQ Question
Which of the following statements about degrees of freedom in molecular motion is correct?
A molecule has three degrees of freedom for translational motion in three-dimensional space.
A molecule constrained to move in a plane has three degrees of freedom for motion.
Degrees of freedom for a molecule moving along a line is zero.
Molecules in thermal equilibrium do not exhibit any degrees of freedom.
Correct Answer
Detailed Explanation
According to the NCERT context, a molecule free to move in space requires three coordinates, implying it has three degrees of freedom for translational motion in three-dimensional space.
