The science of measuring the quantities of heat that are involved in a chemical or calorimetry lab - heat of combustion notes, labs , worksheets.
Evaluation the results of the experiment suggest that the enthalpy of combustion of ethanol lies between 50 and 80 kj mol-1, which is less than 6% of the hypothetical value of 1368 kj mol-1 moreover, it appears that the metallic beaker produced a smaller enthalpy of combustion than the glass beaker, which again contradicts with the hypothesis.
