Spirit Burner Experiment Aim: To perform an experiment in the labs to determine the heats of combustion of selected alcohols and then to use this information and the gathered data from chemical data sources to determine trends in the longer chain alcohols. The Variables that MUST be controlled throughout the experiment are: • The height from spirit burner nozzle to the base of the water filled beaker • Air drafts around the room must be kept to minimum so as to keep the heat on the base of the
