The document describes an experiment conducted to determine the absolute zero temperature through measuring air pressure at different temperatures using a virtual laboratory simulator. Data on pressure and temperature was collected and graphed, showing a direct proportional relationship. The slope of the line was used to determine an equation relating pressure and temperature. By setting pressure equal to zero in the equation, the absolute zero temperature was calculated to be -228.12°C, with a 16% error rate compared to the accepted value of -273.15°C. The experiment demonstrated the direct proportional behavior between the thermodynamic variables of pressure and temperature.
