Question: Comparing the Energy Outputs of Different Fuels. Aim: To investigate the amount of energy released from different fuel sources and to compare respective costs of the fuels per kilo joule of energy transferred.
Answer: Hypothesis: I suggest the longer the hydro-carbon chain of the fuel being burnt the greater the energy released per gram of fuel burnt. However given the price of fuel per gram, typically, does not increase proportionately to the chain length, the fuel releasing the most energy may not necessarily be the most cost effective. Procedure: 1. Start by setting measuring out 200ml of water, transfer to the copper beaker and take the water temperature.
2. Now clamp the beaker to the frame and adjust so that the bottom of the beaker is at a height exactly 4cm from the top of the crucible (when the crucible is directly under it)....(short extract)
