This question has several parts that must be completed sequentially. If you skip a part of the question, you will not receive any points for the skipped part, and you will not be able to come back to the skipped part. Tutorial Exercise In a student experiment, a constant-volume gas thermometer is calibrated in dry ice (-78.5°C) and in boiling ethyl alcohol (78°C). The separate pressures are 0.915 atm and 1.663 atm. Hint: Use the linear relationship PA-BT, where A and B are constants. (a) What value of absolute zero does the calibration yield? (b) What pressure would be found at the freezing point of water? (c) What pressure would be found at the boiling point of water? Step 1 From the linear relationship, we know that the pressure is related to the temperature as P-A+BT, where A and B are constants, and Te is the Celsius temperature. To find A and , we use the given data and tuhit 1:29 x Your response differs from the correct answer by more than 10%.
