일반물리학 1 — Temperature, Heat, and the First Law of Thermodynamics: Problem 26

26 Two constant-volume gas thermometers are assembled, one with nitrogen and the other with hydrogen. Both contain enough gas so that \( p_3 = 78 \text{ kPa} \). (a) What is the difference between the pressures in the two thermometers if both bulbs are in boiling water? (Hint: See Fig. 18-6.) (b) Which gas is at higher pressure?
