Essay

During a science lab, students heated water, allowed it to cool, and recorded the temperature over time. They computed the difference between the water temperature and the room temperature. The results are in the table.

$\begin{array}{|l|l|l|l|l|l|l|}\hline\text { Time (in minutes) }& 10 & 20 & 30 & 40 & 50 & 60 \\\hline \text { Difference in temp. (degrees F)}& 68 & 36 & 20 & 10 & 6 & 4 \\\hline\end{array}$

-Newton's Law of Cooling suggests an exponential function is appropriate. Re-express the data using logarithms and sketch a new scatterplot.
