 Joseph Louis Gay-Lussac

Joseph Louis Gay-Lussac (1778–1850) was a prominent French chemist and physicist. He is best known for his contributions to the fields of gas laws, particularly the relationship between gas temperature and pressure, which is formulated in Gay-Lussac's law. This law states that, for a given amount of gas at constant volume, the pressure of the gas is directly proportional to its absolute temperature.
