B)132.48 Pa
C)131.52 Pa
D)2.07 Pa

Question

Quizplus · Accepted Answer

The change in pressure per degree Kelvin for a constant-volume gas thermometer is given by the pressure at the triple point of water divided by the temperature at the triple point (273.16 K). Therefore, 132.48 Pa / 273.16 K ≈ 0.48 Pa/K.
