CALCULATIONS: 1. Prepare a Temperature vs Time cooling curve for each of the two trials performed with pure stearic acid. Perform a linear regression analysis on both the cooling and the freezing regions for each trial. For Trial 1, show the calculation below for determining the point of intersection between the two lines and the value for the freezing point of pure stearic acid. Identify this point on both graphs by inserting a text box and arrow. Report the average of the two freezing points.
