According to Boyle's law, what is the relationship between the volume and pressure of a gas at a constant temperature?
Explanation
This question assesses understanding of Boyle's law, a fundamental physical principle that governs the mechanics of breathing by relating changes in thoracic volume to changes in lung pressure.
