AIM: The aims of my experiment are to compare the given values of the molar heat of combustion with my experimental values, and to predict the theoretical value of heptanol. PREDICTION: I predict that my experimental values will be lower than the given values. This is because heat will be lost in unnecessarily obtaining the results. This will be by sound and light energy given off, incomplete combustion (complete combustion occurs when there are lots of oxygen atoms available when the fuel burns, and then you get carbon dioxide, as a carbon atom bonds with two oxygen atoms; a limited supply of oxygen results in carbon monoxide being produced), and also conduction, convection and radiation of heat through the air, and draughts speeding the process up. Water will be evaporated, meaning that there is a lower volume of water, causing the remaining water to absorb more heat energy, which will...
