Web1 nov. 2024 · In simple terms, increasing the temperature of a gas increases its pressure, while decreasing temperature decreases pressure, assuming volume does not change. The law is also known as Gay-Lussac's law of pressure temperature. Gay-Lussac formulated the law between 1800 and 1802 while building an air thermometer.
