Absolute Zero

Lab Summary

Use an absolute pressure sensor and a temperature sensor to experimentally determine a numerical value for absolute zero in degrees Celsius.

Theory

Students experimentally determine a numerical value for absolute zero in °C.By doing this, they:

  • Develop an understanding of the direct relationship between temperature and pressure of an enclosed gas with constant volume.
  • Apply statistical methods to experimentally gathered data in order to extrapolate values that are not measurable.
  • Learn how an ideal gas can be used as a thermometer.
