In a student experiment, a constant-volume gas thermometer is calibrated in dry ice (?78.5°C) and in boiling pentane (36.1°C). The separate pressures are 0.910 atm and 1.454 atm. Hint: Use the linear relationship P = A + BT, where A and B are constants.
(a) What value of absolute zero does the calibration yield?
°C
(b) What pressure would be found at the freezing point of water?
atm
(c) What pressure would be found at the boiling point of water?
atm
