Gay Lussac's Law
Gay-Lussac's Law, a fundamental principle in the field of gas chemistry, explores the relationship between the temperature and pressure of a gas at constant volume. Named after the French chemist Joseph Louis Gay-Lussac, this law elucidates that, under such conditions, the pressure of a gas is directly proportional to its absolute temperature. This concise yet pivotal concept, first formulated in the early 19th century, has become a cornerstone in understanding the behavior of gases, contributing significantly to the foundations of thermodynamics and gas laws.
