Pre-Lab on Newton’s Law of Cooling

· Please read the article described in the following link http://jwilson.coe.uga.edu/EMT668/EMAT6680.2001/Abney/WriteUp12/writeup12.html

· Make a scatter plot of the data using EXCEL or another program of your choice.

· Fit the data to the model function, (𝑡)= 𝐴𝑒−𝐵𝑡 +𝐶, where T(t) is the temperature as a function of time t. If you do not know how to fit a function in Excel, you may find examples on YouTube; https://www.youtube.com/watch?v=3Fd4ukzkxps

· From the BEST fit (using the minimization and solver method), find the parameter values of A, B, and C with their appropriate units. Record these values below.

· Print BOTH the spreadsheet and the graph to turn in with your work.

A = ____________________________ ( )

B = ____________________________ ( )

= ____________________________ ( )

 Use the model function that you developed to estimate the time it took for the person to drink his coffee at the desirable temperature of 10°F above the room temperature value at McDonald. Show your work below.
