What principle explains the relationship between pressure and volume of a confined gas?

Boyle's Law is the principle that describes the relationship between the pressure and volume of a confined gas. It states that for a given amount of gas at a constant temperature, the volume of the gas is inversely proportional to its pressure. This means that if the volume of the gas decreases, the pressure increases, and vice versa, as long as the temperature remains unchanged.

The relation is mathematically expressed as ( PV = k ), where ( P ) is the pressure, ( V ) is the volume, and ( k ) is a constant for a specific amount of gas at constant temperature. This principle is crucial in understanding how gases behave under various conditions, which is essential for various applications in aviation physics, such as in understanding how changes in altitude affect the pressure and volume within aircraft cabins and how engines perform under different atmospheric conditions.

Other principles mentioned are related to different physical phenomena. Bernoulli’s Principle addresses the behavior of fluid flow and the relationship between velocity and pressure; Charles's Law pertains to the relationship between volume and temperature of a gas; and Archimedes' Principle deals with buoyancy and floating objects in fluids. These concepts, while important in their own contexts, do not specifically describe the relationship between pressure and
