Data analysis 1. Use the measured data in Tables I to 3 to calculate the measured specific heat (including the average value and deviation) of the three metals. Record the results in Tables 4 to 6. 2. Calculate the % errors between the measured and the literature values of specific heats of the three metals. Record the results in Tables 4 to 6.

If they are OK, your TA will sign them. 3. Clean up your bench. Lab report on Experiments 10 Tables 1 to 6 must be included in your lab report. 2. The answers to the questions listed in each data analysis must be included in your lab report. 3. The answers to the questions in "Questions and Exercises" must be included in your lab report. 4. The required other contents and format for your lab report can be found in the syllabus. 5. You can tear those pages out of the lab manual as a part of your lab report, which contain measured (raw) data and analyzed data, answers to questions. The data sheets must be checked and signed by your lab TA. 91
