The video tutorial demonstrates an experiment to compare the effectiveness of four alcohols—methanol, ethanol, propanol, and butanol—as fuels. The experiment involves burning each alcohol to heat water and measuring the temperature rise. The setup includes alcohol burners, a thermometer, and a stopwatch. Control variables ensure fair testing. Results are recorded and analyzed, revealing butanol as the most effective fuel. The video concludes with a discussion on potential discrepancies in the results and suggests further testing.

Why is it important to record the temperature change in the experiment?
