-
The 1. that the tension of a gas varies directly with the temperature if the volume remains the same.
-
The 1. that when gases or vapors react on each other the volumes both of the factors and of the products of the reaction always bear to each other some very simple numerical ratio.
-
The l. regulating the expansion of gases by heat, which asserts that air and all of the less liquefiable gases have a coefficient of expansion of 1/273; in other words, their volume at any temperature receives an increment equal to 1/273 f their volume at 0 C. for every increase of 1 C. in the temperature, and suffers a corresponding decrement for diminution in the temperature. The 1. is not rigorously exact, although very nearly so for the permanent gases. Moreover, the 1. as enunciated by Gay-Lussac gave a different coefficient from the true one here laid down.
