Understanding Gay-Lussac's Law: A Complete Guide
Gay-Lussac's Law, named after the French chemist Joseph Louis Gay-Lussac, is a fundamental principle in gas laws that describes the relationship between the pressure and temperature of a gas at constant volume. This law states that the pressure of a gas is directly proportional to its absolute temperature when volume is held constant.
What is Gay-Lussac's Law?
Gay-Lussac's Law can be mathematically expressed as: P/T = k (where P is pressure, T is absolute temperature in Kelvin, and k is a constant). This means that for a given mass of gas at constant volume, the ratio of pressure to temperature remains constant.
The formula is more commonly written as: P₁/T₁ = P₂/T₂, where P₁ and T₁ are the initial pressure and temperature, and P₂ and T₂ are the final pressure and temperature.
