Description:

A hollow spherical ball has an Absolute Pressure gauge mounted on it. Heating with boiling water and cooling with ice water causes pressure changes. Absolute zero can be extrapolated by plotting P vs. T and using Boiling Water, Ice Water, and Alcohol and Fry Ice mixture (-80C). Linear line intersects x axis around -270.
