Chemistry coursework FuelsPlanning========Aim---In this investigation I will have to find out which of the intoxicantfuels methanol, ethanol, propanol and butanol, is the opera hat. Thebest one will be the one which creates the most energy whilstburning. installation and reckonion---------------------------A fuel is a substance burned for warmheartedness or power. The best type of fuelis one that can be transported safely without the worry of itcatching on fire, gives out a skunk of heat for a certain mass, does notcost very much, lights quickly, burn slowly, is safe to use and doesnot give off any physique 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 the archetype alcohol by burning requires energy-it is endothermic, makingthe bonds of the new products of burning the alcohol ie carbon dioxideand water gives out energy-it is exothermic.I predict that butanol will requi re the most energy as it has the mostbonds retentiveness the carbon, oxygen and hydrogen atoms together. propanolwill require the second largest substance of energy, Ethanol the thirdand Methanol the least amount of energy to interrupt these bonds.Methanol CH3OHEthanol C2H5OHPropanol C3H7OHButanol C4H9OHPentanol C5H10OHTherefore I predict that Methanol will be the best fuel, followed byEthanol, then Propanol and the worst fuel will be Buta...
