Unformatted text preview: volume of gas at several temperatures measured by an ordinary lab thermometer. Data: Temp Bath T (*C) P (PSI) Cold .25 16.9 Room 22.0 17.5 Hot 90.5 20.9 Sample Calculations: Results: Temperature vs Pressure 5 10 15 20 25-400-300-200-100 100 200 Temperature (*C) Pressure (psi) Calculated Absolute Zero:-366.67*C Absolute Error: 34.2% Discussion and Conclusions: I encountered a problem with our pressure gauge during this experiment. It measures the PSI at room temperature to be 17.5 psi and the accepted value at STP is 14.7 psi. I believe that this may have caused an error in our results because if each point on our graph is 19% higher then our value for the absolute zero is going to be 19% farther than what it would be if we had properly calibrated equipment....
