pressure
boyle's law
at a fixed temperature, the volume of a gas is inversely proportional to the pressure exerted by the gas
charle´s law
at a fixed pressure, the volume of a gas is proportional to the temperature of the gas
Gay-Lussac law
Gay-Lussac´s law states that the pressure of a sample of gas at constant volume, is directly proportional to its temperature in kelvin
Dalton's law
Dalton´s law of partial pressure states the total pressure exerted by a mixture of gases is equal to the sum of the partial pressures of individual gases
