In solids the temperature is the measure of__________________?
Correct answer: B. Vibrational kinetic energy
- A. Average kinetic energy of molecules
- B. Vibrational kinetic energy
- C. Translational kinetic energy
- D. None of the above
Explanation
In a solid, particles cannot move freely from place to place; they vibrate about fixed positions. Therefore temperature is related to the average vibrational kinetic energy of the particles. The likely mistake is choosing a, which is a broader statement often applied to gases, where translational motion dominates.

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.
