According to Boyle's Law, which two variables are inversely proportional?

Boyle's Law states that for a given mass of gas at constant temperature, the pressure of the gas is inversely proportional to its volume. This means that if the volume of the gas decreases, the pressure increases, and vice versa, provided the temperature remains constant. This fundamental principle of gas behavior highlights how gases expand and compress, demonstrating that pressure and volume have a reciprocal relationship.

In this context, the correct identification of pressure and volume as the variables that are inversely proportional is critical for understanding behaviors in thermodynamics and various applications in fields such as HVAC, propulsion, and gas storage. Recognizing this relationship is essential for predicting how changes in one aspect will affect the other within a sealed system.
