Gay-Lussac’s law or Amonton’s law states that the absolute temperature and pressure of an ideal gas are directly proportional, under conditions of constant mass and volume. In other words, heating a gas in a sealed container causes its pressure to increase, while cooling a gas lowers its pressure.
Gay-Lussac's law usually refers to Joseph-Louis Gay-Lussac's law of combining volumes of gases, discovered in 1808 and published in 1809. [1] However, it sometimes refers to the proportionality of the volume of a gas to its absolute temperature at constant pressure.
What is Gay-Lussac’s Law? Gay-Lussac’s law is a gas law which states that the pressure exerted by a gas (of a given mass and kept at a constant volume) varies directly with the absolute temperature of the gas.
Gay-Lussac's Law states that the pressure of a given mass of gas varies directly with the absolute temperature of the gas, when the volume is kept constant. Gay-Lussac's Law is very similar to Charles's Law, with the only difference being the type of container.
Gay-Lussac's law (also known as the pressure law) describes the relationship between the pressure and temperature of a gas when there is a constant amount of gas in a closed and rigid container. The law states that the absolute pressure is directly proportional to the temperature.
The French chemist Joseph Gay-Lussac (1778-1850) discovered the relationship between the pressure of a gas and its absolute temperature. Gay-Lussac's Law states that the pressure of a given mass of gas varies directly with the absolute temperature of the gas, when the volume is kept constant.
Gay-Lussac’s Law elucidates a critical relationship between pressure and temperature in a confined gas system. The law asserts that, at constant volume and mass, the pressure of a gas is directly proportional to its absolute temperature.
Gay-Lussac's law describes how increasing the temperature of a gas with a fixed volume and a constant number of "particles" will result in a similar increase in the pressure of the gas, and vice versa.
Gay-Lussac's law is an ideal gas law which states that at constant volume, the pressure of an ideal gas is directly proportional to its absolute temperature (in Kelvin). The formula for the law may be stated as: Pwhere. PGay-Lussac's law is also known as the pressure law.
What is Gay Lussac’s Law? Gay-Lussac’s law is a gas law that states the pressure of a gas varies directly with temperature when mass and volume are kept constant. As the temperature increases, the pressure will also increase. The concept is shown graphically below.
