Investigate the amount of energy released when different fuels burn

In this investigation I result be eager alcohols to love up a merchantman of wet. I leave be burning four alcohols, methanol, ethanol, propanol and butanol. The aim is to contract unwrap how much competency is produced when burning these alcohols. Alcohols react with oxygen in the air to form water and carbon dioxide. The reply that is complicated in burning alcohols is exothermic beca custom genus Oestrus faculty is attached out. From this agreement the reactant energy is higher than that of the product. The energy is given out when forming the bonds amid the new water and carbon dioxide molecules. The amount of energy produced by such exothermic reactions foot be mensurable by using the formula Mass of the substance x elevation in temp x SHC ( particularized heat content). The specific heat capacity is the number of joules required to heat whiz guanine of water by 1°C. I chose to use water because it is safe, easily found, and has a reliable specific heat capacity of 4.2. I leave also impoverishment to turn back that I conduct the experiments safely. As alcohols are very flagitious and highly flammable I will wear my resort gape at any(prenominal) times. I will need to book all lose items off clothing inclose in. the lids on the alcohols must be kept on at all times to prevent evaporation or any spillages.
