In a student experiment, a constant-volume gas thermometer iscalibrated in liquid nitrogen (−196°C) and in boiling pentane(36.1°C). The separate pressures are 0.347 atm and 1.436 atm.Hint: Use the linear relationship P = A+ BT, where A and B are constants.
(a) What value of absolute zero does the calibrationyield?
°C
(b) What pressure would be found at the freezing point ofwater?
atm
(c) What pressure would be found at the boiling point ofwater?
atm
A hollow aluminum cylinder 22.5 cm deep has an internal capacityof 2.000 L at 15.0°C. It is completely filled with turpentine at15.0°C. The turpentine and the aluminum cylinder are then slowlywarmed together to 65.0°C. (The average linear expansioncoefficient for aluminum is 24 ✕ 10−6°C−1,and the average volume expansion coefficient for turpentine is 9.0✕ 10−4°C−1.)
(a) How much turpentine overflows?
cm3
(b) What is the volume of turpentine remaining in the cylinder at65.0°C? (Give your answer to at least four significantfigures.)
L
(c) If the combination with this amount of turpentine is thencooled back to 15.0°C, how far below the cylinder's rim does theturpentine's surface recede?
cm
