PASCO Absolute Zero Sphere Wireless Bundle

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 any of our data collection software. Once the data is collected, students can use a linear fit to extrapolate the value of absolute zero.  The closed metal sphere of  roughly 405 ml (d = 92 mm) comes with an attached fast response temperature sensor and tubing to connect wireless temperature link and a wireless pressure sensor.
