Which is the correct statement?
Correct answer: C. The average kinetic energy of the molecules in the gaseous state is proportional to the temperature.
- A. The average kinetic energy of the molecules depends on the volume in which the gas is enclosed.
- B. The average kinetic energy of the molecules in the gaseous state is proportional to the pressure.
- C. The average kinetic energy of the molecules in the gaseous state is proportional to the temperature.
- D. All of the above
Explanation
Kinetic energy is the energy a substance has because of its molecules being in motion, as a substance absorbs heat its molecules move faster, thereby increasing the substance's kinetic energy.

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.
