3. Remembering that the heat gained by the water is equal to the heat lost by the metal, calculate the<br />

specific heat of the metal for each trial:<br />

4. Calculate your average value for the specific heat of the metal:<br />

Results and Conclusions<br />

1. Look up the accepted values for the specific heat of the metals and calculate the percent error in the<br />

specific heat value that you determined experimentally.<br />

2. Which of the data you recorded contains the greatest measurement error? Can the percent error in<br />

your specific heat be accounted for by the error in this one measurement?<br />

3. You assumed that the initial temperature of the lead shot was the same as that of the boiling water.<br />

This assumption may not have been correct and may account for some experimental error. What other<br />

assumptions were made that may be sources of error?<br />

4. List the value for the specific heat of lead obtained by three other lab groups. Do you think this<br />

property could be used to identify substances? Explain your answer.<br />

5. If you were looking for a material that was a good insulator, would you prefer a material with a high<br />

or low specific heat capacity? Explain your reasoning.
