Investigate whether firelighter, wood, ethanol, paraffin or wax contains the most energy :: GCSE Chemistry Coursework Investigation

Investigate whether firelighter, wood, ethanol, alkane or wax contains the almost energyEnergy In Different FuelsAim I am going to investigate which fuels contain the most energybetween firelighter, wood, ethanol, paraffin and wax.Prediction I think that the fuel that contains the most energy is the unmatchable that produces the highest rise in temperature of the water. I knowthis because Heat + fuel + atomic number 8 = CO2 + H20 + energy.The energy realised is heat and light energy, which is dependent onthe chemical potential drop energy in the fuel. The greater the chemicalpotential energy the more energy is transferred as heat and light thegreater the rise in temperature.And because of the fire triangletri2.gif (22406 bytes)ApparatusList recrudesce watch ThermometerSplint ClampMatches Boiling tubeHeat deduction matFuelsFirelighter,Wood,Ethanol,Paraffin,Wax.Method (Preliminary test) first of wholly, I depart patch up accepted I take allof the safety precautions, I.e. obli gate back foresightful hair, use goggles andmake sure the path is well ventilated. secondly I exit set out the weapon and get all the equipment from the list (shown on theprevious page). Using the standard cylinder, I willing put 20cm3 ofdistilled water into a boil tube, and take the startingtemperature. In order to make this a fair test I will burn the fuelfor wholeness minute only, use 20cm3 of water and make sure the tip of thefuels scorch is under the boiling tube. After the minute is up, I willblow out the flame or place the lid of the fuel over it, (cutting offthe oxygen). I will past take the finial temperature. Then I will arrogate the experiment for the other four fuels, in order to establishwhich 2 fuels produced the highest rise in temperature of the water.Method - ComparisonI will then compare these two fuels by heating them until they get toa genuine temperature noting down the time every time the temperatureincreases by 10C in order to form a scatter graph victimisation line of bestfit.I will use step one and most of step two from the preliminary test(first of all, I will make sure I take all of the safety precautions,I.e. tie back long hair, use goggles and make sure the room is wellventilated. Secondly I will set out the apparatus and get all theequipment from the list (shown on the previous page). Using themeasuring cylinder, I will put 20cm3 of distilled water into a boilingtube,) I then heat the water using the first fuel until it rises tocenturyC, noting the time every 10C starting from 20C.
