1 kwi 2021 · 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.
Guillaume Amontons was the first to empirically establish the relationship between the pressure and the temperature of a gas (~1700), and Joseph Louis Gay-Lussac determined the relationship more precisely (~1800).
Because of this, the P-T relationship for gases is known as either Amontons’s law or Gay-Lussac’s law. Under either name, it states that the pressure of a given amount of gas is directly proportional to its temperature on the kelvin scale when the volume is held constant .
Amonton's Law Toward the end of the 1600s, the French physicist Guillaume Amontons built a thermometer based on the fact that the pressure of a gas is directly proportional to its temperature. The relationship between the pressure and the temperature of a gas is therefore known as Amontons' law .
The pressure of a given amount of gas is directly proportional to its absolute temperature, provided that the volume does not change (Amontons’s law). The volume of a given gas sample is directly proportional to its absolute temperature at constant pressure (Charles’s law).
3 sie 2016 · According to Amontons’ law, increasing the temperature of a gas while holding its volume constant increases the pressure of the gas. When gas particles heat up and gain energy , they move faster. This increases their collisions with each other and their container, causing greater pressure.
Amontons's law states that the pressure of a gas is directly proportional to its absolute temperature, assuming volume and amount of gas are constant. Mathematically, it is expressed as $P \propto T$ or $P/T = k$ where $k$ is a constant.
