Gay-Lussac’s Law – The pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature.
Law of gaseous volumes or Gay-Lussac’s Law is that when gases combine together they do (1) In simple ratios by volume and (2) the volume of the product, if gaseous, also bears a simple relation to the volumes of the two reacting gases measured under the same conditions of temperature and pressure.
