Chemistry Coursework †Fuels Essay -- GCSE Chemistry Coursework Invest

Chemistry coursework FuelsPlanning========Aim---In this investigation I will have to find out which of the alcoholfuels methanol, ethanol, propanol and butanol, is the crush. Thebest genius will be the one which creates the close energy whilstburning.Introduction and prediction---------------------------A fuel is a substance burned for heat or power. The best type of fuelis one that can be transported safely without the worry of itcatching on fire, gives out a lot of heat for a authentic mass, does notcost very much, lights quickly, burns slowly, is safe to use and doesnot give off any form of polluting gases.When burning alcohols, as I am going to do in this investigation, thereaction is exothermic as heat is given out. Breaking the bonds of theoriginal alcohol by burning requires energy-it is endothermic, makingthe bonds of the spick-and-span products of burning the alcohol ie carbon dioxideand water gives out energy-it is exothermic.I predict that Butanol will require the mo st energy as it has the mostbonds holding the carbon, oxygen and hydrogen atoms together. Propanolwill require the second largest amount of energy, Ethanol the thirdand Methanol the least amount of energy to mark these bonds.Methanol CH3OHEthanol C2H5OHPropanol C3H7OHButanol C4H9OHPentanol C5H10OHTherefore I predict that Methanol will be the best fuel, followed byEthanol, then Propanol and the pommel fuel will be Buta...
