Using software d to plot three graphs using this temperature difference versus time data (you may use any graphing program such as MS Excel or Google Sheets- be sure to paste them onto a Word Document or PDF).

Temperature difference vs. time
ln Temperature difference vs. time (natural log of the temperature difference versus time)
Temperature difference^-1 vs. time (the reciprocal of the temperature difference versus time)

Data Table

Using software d to plot three graphs using this temperature difference

Determine the slope of the line; this is your value for k, the rate constant.
Write the rate law for the cooling of water. This should take the form of Rate = k[temperature difference]ⁿ with the values for k and n substituted.
Using what you know about heat and kinetic energy, and what you have learned on order of reactions, justify the order you determined for the cooling of water.
