Science Investigation AIM: In this investigation we are going to find out which fuel contains the most energy by burning each fuel and using its heat to heat up water. PREDICTION: I predict that Ethanol will contain the most energy. I can backup my answer by referring to my scientific knowledge, Ethanol will burn the quickest because it has more energy stored within its bonds C-C-C. METHOD: In this experiment I will change the fuels, I will use different fuels. I will use 120 ml of water to boil and I will keep that the same all the way throughout the experiment. I will measure the temperature of the water before I heat it and I will use the same amount of fuel each time to keep the experiment fair, I will also keep it a fair test by heating the water for the same amount of time for each fuel.
Below is a list of all the equipment which I will need for my experiment: Different types of fuels Tin lids Thermometer Water Tripod The first thing which I will do is weigh the fuels and note down the results, then I will place a tin lid underneath the tripod and place the first fuel on the tin, then I will measure 120 ml of water and place it in a beaker on top of the tripod and will take down the temperature of the water and then I will burn the fuel and use it to heat up the water for 2 minutes. After 2 minutes I will weigh the fuel and take the temperature of the water, I will repeat this process using all of the fuels and then I will use the following formula to work out the Energy given out: Energy = Mass (g) (0. 120) X 4200 (SHC) X Temp Change. To make the experiment safe I will wear goggles to protect my eyes from any fuel spillage which could damage my eyes.
The Essay on Geothermal Energy 2 Heat Water Hot
I. Overview of Geothermal Energy Geothermal energy (from the Greek words geo [earth] and therme [heat], thus 'earth heat' energy) is a domestic energy resource with cost, reliability, and environmental advantages over conventional energy sources. Energy from this source comes from the renewable source of heat from deep in the Earth (diagram: A). Heat is brought up to near the surface by thermal ...
RESULTS: I will show my result by drawing various different types of graphs and tables. Below are the Energy amounts in J which each fuel gave out: Meta fuel 6552 J Ethanol 12096 J Propane 8064 J Methanol 9072 J Peanut 5049 J To make my results more accurate and fair I measured each fuel more than once. >From looking at my results I have found that Ethanol gives the most energy, which was around 12000 J and then it was Methanol in second place. From my results I can say that my prediction was right and I can say that the reason why Ethanol made the most energy is because it was the strongest because it had more energy stored in its bonds.
If I had more time to improve my experiment I would repeat each fuel several time and I would spend some time comparing my results with my friends.
