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)
The equation shows that, as volume increases, the pressure of the gas decreases in proportion. Similarly, as volume decreases, the pressure of the gas increases. The law was named after chemist and physicist Robert Boyle, who published the original law in 1662.
