Gay-Lussac’s law

Physics
  • 1. When gases combine chemically the volumes of the reactants and the volume of the product, if it is gaseous, bear simple relationships to each other when measured under the same conditions of temperature and pressure. The law was first stated in 1808 by J. L. Gay-Lussac and led to Avogadro’s law.

    2. See Charles’ law.

Chemical Engineering
  • A law stating that if the mass and pressure of a gas are held constant, then gas volume increases linearly as the temperature rises. When gases react, they do so in volumes that bear a simple ratio to one another and to the volume of the product, if it is a gas, temperature and pressure remaining constant. This is sometimes written as V=kT where k is a constant dependent on the type, mass, and pressure of the gas, and T is the absolute temperature. For an ideal gas k=nR/P. It is named after Gay-Lussac (1778–1850) who proposed the law in 1808, which led to Avogadro’s law.
