The data collected for Ethanol is in list 1 and 2.
Sample Data for Experiment
The data is then plotted on a scatter graph to illustrate the rate of cooling.
Scatter Graph Showing Cooling Rate for Ethanol
Similar processes would be conducted to collect data for the other substances and the cooling curves compared.
