Fuels Analysis

Aim: В To find out which in turn fuel provides the most strength.


We will be using six different powers to heat 100ml of water, to see the changes with the temperature. We will measure the temperatures in the water before and after the research. We will burn warmth the water pertaining to exactly a couple of minutes, and check the within temperature. The change in temperature will allow us to work out the vitality given off the fuel by using this formula: В

Mass of water times 4. 2 (water's particular heat capacity) x temperatures change = energy moved from the gas to the drinking water В

When the fuels will be burnt, strength is given away. I will be determining the energy given off using the formulation above. The precise heat potential is the strength needed (Joules) to high temperature 1 gram of normal water by one degrees Celsius. Preliminary Test

To help me decide the vital elements of the test, В I produced a trial using methanol to check if my chosen volumes and set up would work. Outcomes:

Height of can by burner: 5cm

Mass of burner in start = 204. 47g. Mass of burner finish = 203. 6g. Mass of fuel burned = 0. 87g Start temperature = 19oC Finish temperature = 23oC, Temp rise = 4oC

Following the preliminary experiment I actually made some minor adjustments: В Height of can over wick right down to 4cm to enhance contact with fire and stir the water, as the rise in temperatures is too small. В В В

Goggles will be used during the experiment, because it involves glassware and poisonous liquor. Also, if perhaps any liquor is spilt, all open fire would be put off and the alcohol would easily wiped immediately. В

Fair Check

For each evaluation, I i am making sure that the beaker/can may be the same range (4cm) to the tip of the fuel burner. Also, I will make sure that the wick with the burner is actually the same length(1. 5cm), this means that the fire are the same size, so the level of heating will likely be equal. I will change the normal water after every check, so the normal water always starts at related temperatures, protecting against from distort the rising in temperature. I am going to utilize the same amount of drinking water for each test out. Also, Let me prevent the opening of the burner, because a number of the fuels might evaporate, and would impact the weight with the burner. I am going to weigh the burner just before the test, so I could get the accurate weight in case of any evaporation. I am going to use an exact scale which goes at least to one quebrado point, when the burner is not in use, it ought to be covered to stop evaporation. Also, the pot of water must be the same every time, and so the heated area is the same. I would replicate each evaluation 3 times to get a precise result in circumstance if there have been any anomalous results. В


My spouse and i predict that the molecule with all the most bondings, i. at the. Hexanol will probably give off one of the most energy, as it needs more energy to bond the molecules collectively, so this signifies that there are even more energy between bonds. And so when the fuel is burnt off, the ones with an increase of bondings would give off even more energy, therefore temperature surge would be higher, because even more energy is given off by bondings. When alcohols combust with oxygen/air, they produce heat, Therefore my conjecture is that Methanol is going to emit the least energy, and as the bonding gets bigger, the more energy has off, thus Hexanol would give off the many energy.
