A pressure of 10.0 mm Hg is measured using a constant-volume gas thermometer at a temperature of 50.0$\degree$C.What is the pressure (in mm Hg)at the zero-point temperature?
A)31.8
B)11.8
C)8.45
D)54.6
E)68.3

Question

Quizplus · Accepted Answer

The pressure at the zero-point temperature (absolute zero) is calculated using the linear relationship between pressure and temperature in a constant-volume gas thermometer. The pressure decreases as temperature decreases. Converting 50°F to Celsius gives approximately 10°C. Using the proportionality of pressure and temperature, the pressure at 0°C is calculated to be approximately 8.45 mm Hg.
