Imagine that you calibrate a constant-volume gas thermometer in dry ice which has a temperature of -80.0°C and the pressure reading is 0.900atm. You then calibrate it in boiling ethyl alcohol at 78.0°C with the pressure reading being 1.635atm.
a.) What does this temperature calibration yield for the Celsius value of absolute zero? (Warning: You may not be able to use Excel or other fitting program here because of precision issues. We suggest at least finding the slope by hand.)
b.) What is the pressure reading at the freezing point of water?
c.) What is the pressure reading at the boiling point of water?
