Constant volume gas thermometers
WebConstant-volume gas thermometers are big and come to equilibrium slowly, so they are used mostly as standards to calibrate other thermometers. Interactive Visit this site to learn more about the constant-volume gas thermometer. WebJun 13, 2024 · If our ideal gas thermometer has volume V at thermal equilibrium with some other constant-temperature system, the proportionality of V and T means that. T V = 273.16 V273.16. With the triple point fixed at 273.16 K, experiments find the freezing point of air-saturated water to be 273.15 K when the system pressure is 1 atmosphere.
