Which type of movement is shown by the atoms in the solid?
Correct answer: B. Vibrational motion
- A. Translational motion
- B. Vibrational motion
- C. Rotational motion
- D. Linear motion
Explanation
OPTION A: There is no translational motion in solids due to strong intermolecular forces.OPTION B: According to Kinetic Molecular Theory,Solids are rigid in nature as the particles of solids are held in fixed positions and cannot move freely. They can only vibrate about a mean position and thus transfer energy from one place to another.Hence, B is the correct option.OPTION C: There is no rotational motion in solids due to strong intermolecular forces.OPTION D: Solids do not show linear motion.

About Kinetic Molecular Theory
Kinetic molecular theory explains gases as rapidly moving particles separated by large distances, with negligible volume and negligible intermolecular attraction in the ideal model. It relates temperature to average kinetic energy and explains gas pressure, Boyle's and Charles's laws, diffusion, effusion and the conditions under which real gases deviate from ideal behavior.
