Each member of the series has an extra HCH than the member before it. The aim of the experiment was to test the statement: "Do larger molecules produce more heat?" My hypothesis is that alcohols with larger molecules will produce more heat. The following equipment was set up to carry out the experiment: tin beaker, thermometer, matches, ring clamp, retort stand, electronic scale, ruler, 100ml measuring cylinder and methanol, ethanol, propanol and butanol burners. Method: 1. Use the measuring cylinder to measure 100ml of water and pour it into the metal beaker. 2. Place the thermometer into the beaker and record the temperature. 3. Weigh and record the weight of the methanol burner (with cap on). 4. Attach the ring clamp (with beaker) onto the retort stand. 5. Place the burner directly...
