In this investigation I result be ruin alcohols to love up a merchantman of wet. I leave behind be burning four alcohols, methanol, ethanol, propanol and butanol. The aim is to induce unwrap how much energy is produced when burning these alcohols. Alcohols react with oxygen in the air to form water and carbon dioxide. The chemical reaction that is complicated in burning alcohols is exothermic beca routine pepperiness energy is devoted 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 burn be calculated by using the formula Mass of the substance x elevation in temp x SHC ( precise heat content). The specific heat capacity is the number of joules required to heat 1 guanine of water by 1°C. I chose to use water because it is safe, easily found, and has a reliable specific heat c apacity of 4.2. I leave also bring to tally that I conduct the experiments safely. As alcohols are very atrocious and highly flammable I will wear my golosh gape at any times. I will need to book all lose items off clothing insert in. the lids on the alcohols must be kept on at all times to prevent evaporation or any spillages.
