See how to quickly estimate the temperature value of absolute zero using PASCO's Absolute Zero Sphere (TD-8595).
We connect the apparatus to a PASPORT Chemistry Sensor and SPARKlink interface and use the SPARKvue software's manual sampling mode to collect three temperature-pressure data points: at room temperature, in ice water, and in hot water. Using a linear fit, we can extrapolate to determine the temperature at which the pressure would fall to zero.
