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 GayLussac 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....
