Abstract: The PASCO Absolute Pressure Sensor was used to determine the value of the absolute zero, using the concepts of the ideal gas. This experiment was performed in two parts, for determining absolute zero and isothermal compression. For the absolute zero calculation, a tea kettle, watered ice, and dry ice were used to submerse the closed flask in and Data Studio presented the exact pressure, once the temperature of the flask was at 99.5°C, 2.3°C, and/or -75.7°C. The second part of the experiment involved compressing the gas, through volume markings on the syringe, where Data Studio calculated the exact pressure at five different positions. With the assistance of scatter plot graphing, a linear relationship was recorded for the temperature vs. pressures and the volumes vs. pressures. Possible sources of error include
