The student has provided a focused and detailed description of the main topic and research question. They have also given relevant and focused background information on how alcohols can be used as fuels. The chemistry of the alcohol and the enthalpy change are well explained, and the methodology of the investigation is appropriate and focused on answering the research question. The student has taken appropriate steps to assure the relevancy and validity of the obtained results by repeating measurements for each alcohol 9 times in order to minimize random errors and get more accurate results. The student also shows full awareness of safety hazards, ethical concerns, and environmental issues that can arise during the experiment.
