the law that states that the pressure and volume of a fixed quantity of a gas are inversely proportional under constant temperature conditions

Dalton's law

the law that states that the total pressure exerted by a mixture of gases is the sum of the individual partial pressures of the gases in the mixture

Charles's law

the law that states that the volume and absolute temperature of a fixed quantity of a gas are directly proportional under constant pressure conditions
