Investigate the amount of energy released when different fuels burn
In this investigation I will be burning alcohol's to heat up a can of water. I will be burning four alcohol's, methanol, ethanol, propanol and butanol. The aim is to find out how much energy is produced when burning these alcohols. Alcohol's react with oxygen in the air to form water and carbon dioxide.
The reaction that is involved in burning alcohols is exothermic because heat is given out. From this reason the reactant energy is higher than that of the product.
The energy is given out when forming the bonds between the new water and carbon dioxide molecules. The amount of energy produced by such exothermic reactions can be calculated by using the formula Mass of the substance x rise in temp x SHC (specific heat capacity). The specific heat capacity is the number of joules required to heat one gram 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 will also need to ensure that I conduct the experiments safely. As alcohol's are very dangerous and highly flammable I
