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

Absolute Zero
A constant-volume gas thermometer is used to determine the value of absolute zero in degrees Celsius by plotting Temperature vs. Absolute Pressure and finding the temperature at which the Absolute Pressure is zero.
