Investigate the amount of energy liberated when different alcohols are burnt. For this investigation I will be burning 5 alcohols to heat up a beaker of water placed above. The alcohols I will be burning are methanol, propanol, pentanol, heptanol and octanol. My aim is to find out how much energy is produced when burning these alcohols and whether the number of carbon and hydrogen atoms effects this. Alcohols react with oxygen from the air to form water and carbon dioxide. Alcohols general formula is Cn H n + 1OH and is defined as a series of organic homologous compounds. The reaction that is involved in burning alcohols is exothermic because it gives heat off. The energy is given out when the forming bonds between the water and carbon dioxide molecules. The amount of energy produced by the exothermic reaction can be calculated by using the general formula Mass x rise in temp...
