Please correct my spreadsheet data and answer the questions:

1. Enter the data in the spreadsheet file created for this experiment. Print out the graphs.

For each graph use a ruler to draw in the vertical and horizontal portions of the curves.

Find the temperature at the intersection and note it on the graph.

2(a) For each aluminum run calculate the heat capacity of the apparatus.

You will need to look up the true value of the specific heat of aluminum.

(b) Calculate the average of the individual values.

3(a) For each copper run calculate the specific heat of the metal.

(b) Calculate the average of the individual values.

(c) Calculate the percent error of your average value. You will need to look up the true value

of the specific heat of copper. Comment on the magnitude of your percent error and its

meaning.
