Abstract or “Executive Summary”: In one brief concise paragraph not to exceed 150 words, give the reader enough information to understand what the experiment was about, what was done, and what conclusions were drawn. It is read first and encapsulates the major portions of the report and addresses a reader who may not read the rest of the document. This is not the experimental write up from item #4, or the complete conclusion from item #10, but includes a summary of what was done, and what was concluded. It should contain the highlights of the major parts of the report, including the objective, results, conclusions and recommendations. It does not include details. Introduction The objective of this lab was to use Charles’ Law to calculate the change in volume of a confined gas when the gas temperature changes. Charles’ Law comes from the French scientist, Jacques Charles. He went on many hot-air balloon flights and was interested how the temperature of the gas affected the volume of the gas. He noticed that with an increase in temperature there was an increase in volume. This only works if the pressure of the gas remains constant. In this lab we used an air chamber submerged water and connected to a precision-bore pyrex cylinder to calculate how temperature affects volume. The water that the air chamber was submerged in started off ice cold and was slowly heated close to water’s boiling point. We found that temperature and volume were directly related.

Experimental Data: This table is our initial recoding I the experiment the temperature and the calculated final volume. Table 1: Raw data temperature measurements h (mm)
6. Sample calculations: Each different calculation should be presented so that the reader can understand how the results are obtained. Statements or comments should be made during the presentation of the calculations. The reader should be able to follow all steps. Make sure units are included.

7. Experimental Results: In this table we show the calculated results then compare them to the predicted results. Table 2: Calculated and results of final volume readings.
8. Discussion of Results: This section is devoted to your interpretation of the outcome of the experiment or work. Comment on the graphs, results, or any other aspect of the experiment that is pertinent to the conclusion. A set of questions is generally given to provide a starting point for the discussion. Do not confine the discussion to merely answering the questions. Compare your results to expected behavior and explain any differences. 9. Conclusion: This is the most important part of the report. State conclusions that can be justified with the data. The conclusion must be based on experimental results and also on the entire procedure and theory of the experiment. Report on whether the Objectives of the experiment were realized or not. Make sure that thoughts are worded as conclusions, and not observations. Make simple declarative statements, and do not ramble into a discussion. Conclusions should tell how the results of this experiment can be applied to other experiments. All statements need to refer directly to the current data. Be sure to address all questions presented in the Laboratory Experiment write-up as well as other questions that may have been developed during the experimental procedure in class.
10. Appendix: Include an appendix with material (as required). Separate sections within the appendix must be labeled as : Appendix A, Appendix B, and so forth.
