12. [4/5 Points] Two students in a physics lab have to construct a constant-volume gas thermometer as part of their end of year project. They use dry ice (-78.5°C) and boiling pentane (36.1°C) to calibrate the thermometer. The corresponding values of pressure are 0.390 atm and 1.575 atm. The students plot a pressure versus temperature graph with pressure on the y-axis and temperature on the x-axis. (a) Determine the y intercept and slope of the linear graph that relates the pressure to the temperature. slope ✓ atm/°C atm 79/7640 y intercept 1.2 DETAILS PREVIOUS ANSWERS OSCOLPHYS2016 13.3.WA.038. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER (b) What value of absolute zero do the students get from this calibration? 0 X Absolute zero corresponds to a pressure of zero for a gas maintained at constant volume. °C (c) What pressure readings would this thermometer give for the freezing and boiling points of water? freezing point 1.2 ✓ atm boiling point 2.23 ✓ atm Additional Materials Reading
