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 combined volume of two substances is usually greater than the volume of one of the substances. However, sometimes one substance dissolves in the other and the combined volume is not additive. In differential geometry, volume is expressed by means of the volume form, and is an important global Riemannian invariant.
