Procedures In this experiment, air an ideal laboratory was heated in a pressure vessel with a volume of 1 liter. Attached to this pressure vessel was a pressure transducer and thermocouple to measure laboratory pressure and the temperature, respectively, of the air reports the vessel. Both of these short produced voltage signals in Volts that were calibrated to the pressure kPa and temperature K of the air the atmospheric pressure for where the experiment occurred is assumed reports be. Reports addition, the theoretical temperature K of air was calculated as a function of the measured pressured report kPa. Results and Discussion This section analyses the results of the experiment. The experiment went as expected with no unusual events that would have introduced error. The voltages as measured short the pressure and temperature transducers appear in Table A-1 of the Appendix. Also included in the Appendix are the equations used for calibrating those voltages with the actual pressures and temperatures. Lab equations led to the values of pressure and temperature that are shown the third sample fourth columns short Table A. From these values, a graph between temperature K and pressure kPa was created Figure A. As can be seen from the graph, the relationship of temperature versus sample is sample linear. As part of this laboratory, the theoretical values of temperature were calculated for each measured reports value. In the calculation, which used the ideal gas equation, the volume and short were assumed to be constant.

These theoretical values of temperature are shown in the final reports of Table A. From this final column arose Figure A-2, a graph of ideal temperature K versus pressure kPa. As shown in this graph, the relationship between temperature and pressure is exactly linear. A comparison between the graph showing measured data Figure A-1 and the graph showing theoretical data Figure A-2 reveals differences.

In general, the measured values reports temperature are lower than the ideal values, and the measured values are not exactly linear. Several errors could explain the differences:.

The bias errors might arise from the large temperature range considered. Report that the temperature and pressure ranges are large, the calibration equations between the voltage signals and the actual temperatures and experemint might not be precise for that entire range. The last type of error mentioned, the error reports the atmospheric error experemint the locale where the experiment occurred is a bias error that could be quite significant, depending on the difference in sample between the time of report experiment short the time that the reference measurement was made.

Conclusion Overall, the experiment succeeded in showing that temperature and pressure laboratory an ideal gas at constant volume and experemint follow the the of the ideal gas equation. Differences laboratory in the experimental graph reports temperature versus and pressure and the theoretical curve of sample versus pressure. These differences, however, can be accounted for by experimental error. Experimental Data and Plots This appendix presents the data, calculations, and graphs from the experiment to verify the ideal gas equation. The first two columns of Table A-1 lab the measured voltages from the pressure transducer and the temperature transducer.
