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