Concept:Boyle's law describes how the pressure and volume of a fixed mass of gas are related when temperature is held constant.Explanation:At constant temperature, pressure and volume have an inverse relationship.This means that as pressure increases, volume decreases proportionally.Mathematically, this is written as:$P \propto \frac{1}{V}$When the proportionality sign is replaced by a constant $K$, the equation becomes:$P = \frac{K}{V}$Multiplying both sides by $V$ gives the standard expression:$$PV = K$$Here, $P$ is the pressure of the gas, $V$ is its volume, and $K$ is a constant for the given amount of gas at a fixed temperature.Answer:Boyle's law is expressed mathematically as $PV = K$.
