(8%) Problem 9: A constant-volume thermometer consists of arigid bulb and a pressure gauge. To obtain accurate results, thisthermometer must be calibrated at a known pressure and temperature.Once this is done, the bulb is sealed off from the atmosphere. Thevolume and number of moles of gas can no longer change and thetemperature is calculated from the pressure measurement. No AttemptNo Attempt 25%
Part (a) A particular constant-volume thermometer is calibratedby opening it to the atmosphere while the bulb is in a bath ofboiling water. Enter an expression for the temperature of thethermometer, in degrees Celsius, in terms of its pressure, P, inatmospheres. Answer 25%
Part (b) When the constant-volume thermometer that wascalibrated as described in part (a) is used to measure atemperature, it shows a pressure of 0.92 atm. What temperature isit indicating, in degrees Celsius? T = 92
Part (c) The thermometer is recalibrated by opening it to theatmosphere while the bulb is in a bath of ice water. Enter anexpression for the temperature of the thermometer, in degreesCelsius, in terms of the pressure, P, in atmospheres.
Part (d) The recalibrated thermometer of part (c) shows apressure of 0.92 atm. What temperature does that indicate, indegrees Celsius?
