Evaluation of the Relationship between Temperature and Volume of an Ideal Gas

This is not a formal lab report but it must be typed . Your lab report will consist of three sections: Results, Discussion and Questions. The lab report must be typed using a 12 point font. Reports not typed will lose points. All parts to report must be typed with correct formatting. No excuses. Cursive or ornate fonts are not acceptable. Be careful with spelling and grammar. Poor spelling and grammar detract from a reader’s overall impression of the report. Spelling and grammar errors will lose one point each.

Your report will be graded out of thirty points possible as follows:

Results. (10 points) This section should include your results:

Your results should include a table on the data collected, i.e. the actual measurements of volume at each temperature and the predicted volume at each temperature using the combined gas law

You should prepare a graph of your data with lines for the expected and measured data being sure to correctly identify the dependant and independent variables.

Discussion (10 points):

Your discussion should include at least three paragraphs. In the first, summarize the experiment. In the second, explain your results and your reasoning. Make specific references to your numerical results. In the third paragraph, discuss some potential sources of error and how they might be correct if the experiment were to be repeated. Each paragraph should be in excess of 75 words.

Questions. (10 points – 2 points per question) Answer the following five questions:

1. Is the effect of temperature on the flask instantaneous? Explain.

2. How might the presence of water vapor influence your results?

3. What useful invention to Robert Boyle develop from his work?

4. What do you suppose would happen to a gas eventually if you kept increasing the pressure?

5. On a temperature (x) versus pressure (y) graph, what should be the intersection of the graph with the x-axis?

Appearance, Spelling and Grammar More than one spelling error and you will lose a point. For major grammar errors (sentence fragments, run-on sentences, comma splices, etc.), you will lose a point. You will lose points for appearance if you incorporate non-typed material into your report or if you use non-standard paper (e.g. notebook paper) in your report.
