Ch 1, Lesson E, Page 11 - The Ideal Gas Thermometer A gas thermometer consists of a small bulb that contains the gas and is connected by a small tube to a manometer. Constant-Volume Gas Thermometer ⇒In every case, regardless of what gas is used, the pressure extrapolates to zero when the temperature is –273.15 oC. A thermometer in which the volume occupied by a given mass of gas at a constant pressure is used to determine the temperature. Ch 1, Lesson E, Page 12 - Calibrating an Ideal Gas Thermometer Calibrating a gas thermometer is similar to calibrating any other type of thermometer. You must let the gas bulb equilibrate thermally with a system at a very well known reference temperature, such as the triple point of water. When we extrapolate the straight line towards zero pressure, the temperature approaches the absolute zero at T 0 = −273.15 C .

(ii) Electrical Resistance of Metals R t = R 0(1 + αt + βt 2) where α and β are constants for a metal. The pressure of the gas in a constant volume gas are thermometer are 8 0 c m, 9 0 c m and 1 0 0 c m of mercury at the ice point, the steam point and in a heated … for a constant-volume gas thermometer at very low density. • interpolating constant-volume gas thermometers from 3 K to 24.5561 K, • platinum resistance thermometers from 13.8033 K to 1234.93 K and • Planck radiation law at higher temperatures. (b) The three values 4 Using a constant-volume gas thermometer, a student finds values of 1.374, 1.370, and 1.368 for the ratio of the steam-point pressure to the triple-point pressure. The separate pressures are 0.910 atm and 1.590 atm. The thermometer is then moved to a bath of boiling water (100.0 C). Centigrade thermometer, centigrade thermometer clinical thermometer constant pressure air thermometer constant pressure thermometer, constant-pressure thermometer constant volume air thermometer constant volume gas , () In a student experiment, a constant-volume gas thermometer is calibrated in dry ice (-78.5 C) and in boiling methyl alcohol (64.7 C). (a) Determine the corresponding steam points. For a constant pressure gas thermometer, using the ideal gas equation u will see that temp. The volume can be varied, and the effect this has on the pressure can be measured. Himanshu … pincreaseswithtemperature,T, according to the ideal gas law: pV constant = nRT (1.4) 2 constant. A constant-volume gas thermometer can measure temperature from – 200 C to 500 C. (ii) Electrical Resistance of Metals: R t = R 0 (1 + αt + βt²) where, α and β are constants for a metal. A constant volume gas thermometer containing helium is immersed in boiling ammonia (−33 C) and the pressure is read once equilibrium is reached. Gas thermometers There are two main types of gas thermometer, one operating at constant volume and the other at constant pressure. The influence of all corrections of interest is given in comparison with4He gas thermometry and with4He and3He vapor pressure thermometry. Meyer, C.W. and Reilly M.L., "Realization of the ITS-90 at NIST in the Range 3.0 K to 24.5561 K using an Interpolating Constant Volume Gas Thermometer" in … I3-52: CONSTANT VOLUME GAS THERMOMETER - ABSOLUTE ZERO A d d i t i o n a l I n f o I3-52 Determine the value of absolute zero. Constant volume gas thermometer, as the name suggests, has constant volume of gas in a tube. Temperature Ranges of Application Constant Volume Thermometer •Named after Sir Fancis Simon •Helium is an ideal gas down to 5 K •Modern versions use in situ pressure gauges at low T with electrical read-out (no gas line RT depends only upon volume as the rest of the terms are constant.
