Temperature and Pressure Measurements of an Ideal Gas That Is Heated in a Closed Container IntroductionThis report discusses an experiment to study the relationship of temperature and pressure of an ideal gas (air) that was heated in a closed container.

The objective of the experiment is to test whether the ideal equation of state holds. In the equation, pV = mRT, where p is the pressure the gas, V is the volume, m is the mass, R is a constant, and T is temperature.

This report presents the procedures for the experiment, the experiment's results, and an analysis of those results. ProceduresIn this experiment, air (an ideal gas) 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 the pressure and the temperature, respectively, of the air inside the vessel How to write a report or recount of your experimental procedure; how to give background information for your experiment by answering questions on the report .

In addition, the theoretical temperature (K) of air was calculated as a function of the measured pressured values (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 for the pressure and temperature transducers appear in Table A-1 of the Appendix.

These equations led to the values of pressure and temperature that are shown the third and fourth columns of Table A-1 13 Jan 2016 - Chemistry Lab Resources (for CHM 1XX and 2XX Labs): Parts of a lab The purpose of writing reports you've performed is to communicate .

From these values, a graph between temperature (K) and pressure (kPa) was created (Figure A-1).

As can be seen from the graph, the relationship of temperature versus pressure is roughly linear. As part of this experiment, the theoretical values of temperature were calculated for each measured pressure value.

In this calculation, which used the ideal gas equation, the volume and mass were assumed to be constant Lab reports are an essential part of scientific study and knowledge. For any chemistry lab report, you will need to write down or type the entire procedure and .

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 of temperature are lower than the ideal values, and the measured values are not exactly linear.

Several errors could explain the differences: precision errors in the pressure transducer and the thermocouple; bias errors in the calibration curve for the pressure transducer and the thermocouple; and imprecision in the atmospheric pressure assumed for the locale.

The bias errors might arise from the large temperature range considered FOR CHEMISTRY AND BIOCHEMISTRY STUDENTS ideas of what a lab report should look like, so it is recommended that you ask exactly what they..

Given that the temperature and pressure ranges are large, the calibration equations between the voltage signals and the actual temperatures and pressures might not be precise for that entire range. The last type of error mentioned, the error in the atmospheric error for the locale where the experiment occurred is a bias error that could be quite significant, depending on the difference in conditions between the time of the experiment and the time that the reference measurement was made.

ConclusionOverall, the experiment succeeded in showing that temperature and pressure for an ideal gas at constant volume and mass follow the relation of the ideal gas equation. Differences existed in the experimental graph of temperature versus and pressure and the theoretical curve of temperature versus pressure.

These differences, however, can be accounted for by experimental error Basic Format of a Chemistry Lab Report Writer's Web (printable version here). Abstract - The abstract is a brief summation of the experiement. It should not .

The first two columns of Table A-1 show the measured voltages from the pressure transducer and the temperature transducer. Column three shows the measured values of pressures calculated from the following calibration curve for the pressure transducer: p = 4.

Finally, column 5 presents the ideal values of temperature for the corresponding measured values of pressure.

These ideal values arise from the ideal gas equation (PV=mrt). Figure A-1 shows the graph of temperature (K) versus pressure (kPa) for the measured case.

Figure A-2 shows the graph of temperature versus pressure for the ideal case.
