Absolute Zero Sphere

Product Code: TD-8595


The Absolute Zero Sphere is an effective tool for determining absolute zero temperature. Students connect Pressure and Temperature Sensors before immersing the sphere in water baths of varying temperatures. As the pressure and temperature change, a live graph is generated in PASCO Capstone™. Once the data is collected, students can use a linear fit to extrapolate the value of absolute zero.


  • Experimentally determine the temperature of absolute zero
  • Investigate the relationship between pressure and temperature (Gay-Lussac’s Law)
  • Discover the Ideal Gas Law
