Definition of Law of Combining Volumes: A relation stating that the relative volumes of gases in a chemical reaction are present in the ratio of small integers (assuming all gases are at the same temperature and pressure). Also Known As: Gay-Lussac's Law. Examples: In the reaction. 2 H2(g) + O2(g) â 2 H2O(g)
Boyle's law or the pressure-volume law states that the volume of a given amount of gas held at constant temperature varies inversely with the applied pressure when the temperature and mass are constant. PV = C. When pressure goes up, volume goes down. When volume goes up, pressure goes down.
