Which law states that the volume of a gas is inversely proportional to its pressure at constant temperature?

Boyle's Law describes the relationship between the volume and pressure of a gas, stating that at constant temperature, the volume of a gas decreases as its pressure increases, and vice versa. This means that if you were to compress a gas (increasing pressure), the volume will decrease proportionally, and if you expand the gas (decreasing pressure), its volume will increase proportionally. The mathematical expression of Boyle's Law can be written as ( P \times V = k ), where ( P ) is pressure, ( V ) is volume, and ( k ) is a constant for a given amount of gas at a constant temperature.

In contrast, Avogadro's Law relates volume to the number of moles of gas, Charles's Law relates volume to temperature at constant pressure, and Dalton's Law deals with the partial pressures of gases in a mixture. Understanding these distinctions is crucial in grasping how different factors influence gas behavior under various conditions.
