Let P 3 be the pressure of the bulb of a constant-volume gas thermometer when the bulb is at the triple-point temperature of 273.16 K and let p be the pressure when the bulb is at room temperature. Given are three constant-volume gas there mometers” for A the gas is oxygen and p 3 =20 cm Hg; for B the gas is also oxygen but p 3 = 40 cm Hg; for C the gas is hydrogen and p 3 =30 cm Hg. The measured values of p for the three thermometers are p A , p 8 , and pc’ (a) An approximate value of the room temperature T can be obtained with each of the thermometers using T A =(273.16 K) (p A /20 cm Hg), T B =(273.16 K) (p B /40 cm Hg), T C =(273.16 K) (p C /30 cm Hg). Mark each of the following statements true or false: (1) With the method described, all three thermometers will give the same value of T. (2) the two oxygen thermometers will agree with each other but not with the hydrogen thermometer. (3) Each of the three will give a different value of T. (b) In the event that there is a disagreement among the there thermometers, explain how you would change the method of using them to cause all three to give the same value of T.
