Boyle's Law primarily addresses which relationship?

1. Pressure-temperature relationship

2. Pressure-volume relationship

3. Volume-temperature relationship

4. Volume-mole relationship

The correct answer is: Pressure-volume relationship

Boyle's Law specifically addresses the relationship between pressure and volume of a gas, stating that at a constant temperature, the pressure of a gas is inversely proportional to its volume. This means that if the volume of the container holding the gas decreases, the pressure increases, and vice versa, as long as the temperature is kept stable. This relationship is fundamental to understanding how gases behave under varying pressure conditions and is crucial in fields such as physics, chemistry, and hyperbaric medicine. The other options focus on different gas laws: the pressure-temperature relationship aligns with Gay-Lussac's Law, the volume-temperature relationship relates to Charles's Law, and the volume-mole relationship involves Avogadro's Law. Each of these describes distinct aspects of gas behavior, emphasizing the uniqueness of Boyle's Law in addressing the specific interplay between pressure and volume alone.
