Gay-Lussac Biography and Explanation of first law Joseph Louis Gay-Lussac was a French chemist and physicist. He was known mainly for his two laws related to gases. Today we will be focusing only on his gas law pertaining to the relationship between temperature and pressure. Gay-Lussac was born in Saint-Léonard-de-Noblat which is southeast of Paris. Lussac received a home education during his youth and in 1794 he was sent to Paris to attend l’École Polytechnique where he was admitted in 1797. Three years later he was transferred to the École des Ponts et Chaussées where he became C. L. Berthollet’s, who was an old reputable chemist, assistant. In 1809 he became a professor in chemistry and shortly after that he became professor of physics at the Sorbonne. In 1831 he was elected to the chamber of deputies and later on to the chamber of peers to represent Haut-Vienne which was the region where he was born. Gay-Lussac married Marie-Joseph Rojot in 1809 fathered five children, of whom

Unformatted text preview: the eldest became and assistant for the highly regarded chemist Justus Liebig. Now onto the law that he discovered in 1802. The law which Gay-Lussac formulated lets us calculate pressure in atmospheres and temperature in Kelvin’s. Simply put the law tells us that the pressure of a fixed mass and fixed volume of a gas is directly proportional to the gas's temperature. To put that in simpler terms it tells us that if a gas's temperature increases then so does its pressure, if the mass and volume of the gas are held constant. So now we know we’ve learned that we have this guy who created a law with a formula to calculate a desired pressure or temperature of a fixed amount of gas. Well one might ask how do we know this is true? Well the law holds true because by definition temperature is a measure of the average kinetic energy of a substance and as the kinetic energy of a gas increases, its particles collide with the container walls more rapidly, thus increasing the pressure....
