Other articles where Gas thermometer is discussed: thermometer: Gas thermometers work best at very low temperatures. The Pressure Law (Gay-Lussac’s Law) gives the relationship between the pressure and temperature of a fixed mass of gas at constant volume. A gas thermometer, also known as a gas expansion or gas actuate thermometer is capable of measuring a wide range of temperatures. It states that, for a given mass of an ideal gas at constant pressure, the volume is directly proportional to its absolute temperature, assuming in a closed system.. Liquid thermometers were once the most common type in use. It also shows that if the gas is cooled to absolute zero then the energy of the molecules is at the lowest energy state and therefore cannot generate any pressure. (a) When a gas is heated, the average kinetic energy of the molecules increases.
