In a student experiment, a constant-volume gas thermometer is calibrated in liquid nitrogen (-196°C) and in boiling allyl alcohol (97°C). The separate pressures are 0.350 atm and 1.736 atm. Hint: Use the linear relationship P = A + BT, where A andB are constants.
(a) Obtain value of absolute zero does the calibration yield?
___________°C
(b) Find what pressure would be found at the freezing point of water?
___________atm
(c) Find what pressure would be found at the boiling point of water?
