COMPARING THE ENTHALPY CHANGE OF COMBUSTION OF DIFFERENT ALCHOHOLS.

"Generally very good, with a few minor points for improvement. The introductory theory is generally impressively thorough, with effective use of diagrams to illustrate the discussion. I would note that while the author has evidently performed come calculations to determine predicted enthalpy changes, these have not been explained in the report itself as would be desirable. The method is fairly clear, though perhaps a little too 'wordy' - ideally a method should be as concise as possible to allow it to be easily read by the person carrying out the experiment. Finally, the analysis is very strong (though beware using 3D graphs - they aren't as clear as 2D) and there is a strong quantitative consideration of errors with some relevant suggestions to improve the method. For best quality of the report, the author needs to go one step further with the error analysis and apply the % error to the experimental results to give a range of experimentally supported enthalpy values.
