Investigating Fuels :: Papers

Investigating Fuels Aim To find out the heat of combustion in the five fuels Methanol, Ethanol, Propanol, Butanol, Pentanol, All of these alcohols are apart of the Hydrocarbon chain. Apparatus I will need the following to carry out my investigation for the Experiment Top pan balance - To measure the clog of the fuel. Clamp Stand - To hold the boiling tube above the crucible. Boiling tube - To hold 30 cubic centimetres of water in. Heat proof insipid - So the Bunsen burner doesnt burn the table. Bunsen burner - I need the flame to light the taper. Measuring cylinder - To measure 30cc of water in. Mineral wool - So the taper can light the fuel easier. A stop clock - To time how long the fuel will burn. Taper - To light the fuel by using the flame from the Bunsen burner. Ruler - To measure the distance from the crucible to the boiling tube. Crucible - To carry the mineral wool and fuel in it. diagram Plan First of all, I will set t he clamp stand 3.5cm vertically higher then the crucible which then I put rough mineral wool in and 30 drops of the fuel in. After that I am going to weigh the crucible making sure there is no other liquid or any other substances on the weigher, so I dont do not get any anomalous results. After I have recorded the weight I am going to place the crucible directly under the boiling tube, like shown in the diagram, and then I am going to move 30 cubic centimetres into the measuring cylinder. To make sure I have exactly 30 cubic centimetres in the cylinder I have to get down on my knee and get my eye sight level to the mark which is labelled 30cc to get the experiment as accurate and reliable as I can. When I am satisfied with how much water I have got in the cylinder, I will pour it in the
