Heating & Cooling of Stearic Acid
You will be observing the changes of stearic acid as it changes from solid to liquid by heating,
and then from liquid to solid as it cools down again. You will be recording the temperature at a
number of points as the ice is heated.

Take an initial temperature reading before turning on your flame
Turn on your flame and begin timing your experiment, making sure to use a small flame
Record the temperature on the data results sheet every thirty seconds
Stop the experiment once the stearic acid reaches ~70 Degrees
On a new table, record the results of the stearic acid cooling again by taking a
temperature measurement every thirty seconds
6. Transfer your results to the spreadsheet on Google Classroom
