CONSTANT PRESSURE GAS THERMOMETER: For a constant pressure gas thermometer if we use the ideal gas equation then we will see that temperature depends only on the volume as other terms are constant. A more accurate form of constant-volume thermometer has been designed where some of these errors are reduced, the dead space is made as small as possible and the bulb containing the gas is large (1.6 litres). It measures temperature in the range from o k 5oo k. (a) What is the pressure at 45.0☌? For equation 1, where a = 273.16 K, b = 0, Ptpis the pressure of the ga…. As mentioned previously, the constant volume gas thermometer uses values from the triple point of water to calibrate other thermometers. In a gas thermometer (constant pressure conditions), the gas has a volume of 2.00 L at 85.0☌.
Note that data could have been collected with th… Which of the following thermometers can respond quickly to small temperature changes and are used in small or precise locations? In such gas thermometers, gas temperature changes in the bottle are proportional to pressure changes. Metrologists (experts in the science of measurement) have chosen the constant-volume gas thermometer for this purpose.
