At constant volume, the pressure of a fixed mass of gas is directly proportional to its absolute temperature. This is
Correct answer: C. Gay-Lussac's law
- A. Boyle's law
- B. Charles's law
- C. Gay-Lussac's law
- D. Avogadro's law
Explanation
Gay-Lussac's law covers the pressure temperature relationship at constant volume, and it explains why a sealed aerosol can explode when heated. Boyle's law fixes temperature and relates pressure to volume, while Charles's law fixes pressure and relates volume to temperature. Each law holds one variable constant, which is the quickest way to tell them apart.

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.
