  • n. French chemist and physicist who first isolated boron and who formulated the law describing the behavior of gases under constant pressure (1778-1850)


Sorry, no etymologies found.


  • In 1804 Gay-Lussac made several daring ascents of over 7,000 meters above sea level in hydrogen-filled balloons — a feat not equaled for another 50 years — that allowed him to investigate other aspects of gases.

    Gay-Lussac, Joseph Louis

  • In 1808 Gay-Lussac announced what was probably his single greatest achievement: from his own and others 'experiments he deduced that gases at constant temperature and pressure combine in simple numerical proportions by volume, and the resulting product or products — if gases — also bear a simple proportion by volume to the volumes of the reactants.

    Gay-Lussac, Joseph Louis

  • But Danish geophysicist Niels Kristian Hoejerslev believes it's the Gay-Lussac theory (formula above) mixed with a splash of Bernoulli that does the trick.


  • Gay-Lussac did; but then the blood burst from their mouths and ears.

    Five Weeks in a Balloon

  • Gay-Lussac tower introduced in manufacture of sulfuric acid, largely replacing John Roebuck's lead-chamber process (1746).

    b. Materials and Construction

  • Gay-Lussac burettes may then be used in the titration of only 0.010 meter internal diameter, and graduated into one-twentieth c. c., which allows of great exactitude in the determination.

    Scientific American Supplement, No. 401, September 8, 1883

  • It is well enough to note, that, when we use the word volume or measure, in speaking of the atmosphere or any gaseous body, we adopt the theory of Gay-Lussac, who discovered that gases unite with each other in definite proportions whenever they enter into combination.

    The Atlantic Monthly, Volume 06, No. 33, July, 1860

  • -- M. FREM., successor to Gay-Lussac in the chair of chemistry at the Garden of Plants, Paris, has submitted to the French Academy the results of his _Chemical Researches on Gold_.

    The International Monthly, Volume 3, No. 1, April, 1851

  • _ -- Gay-Lussac, Humboldt, and Boussingault have shown, that when the whole of the moisture and carbonic acid have been removed from the air, it still contains a small quantity of carbon and hydrogen; and Saussure has rendered it probable that they exist in a state of combination as carburetted hydrogen gas.

  • Lewy at Copenhagen; and similar results have also been obtained from air collected by Gay-Lussac during his ascent in a balloon at the height of
