An investigation to find out which alcohol is the best fuel

Extracts from this document...


An investigation to find out which alcohol is the best fuel Plan I am going to set up an experiment to find out which alcohol makes the best fuel out of Methanol, Ethanol, Propanol and Butanol. Apparatus The equipment I am going to use to carry out this investigation is: * Stand and Clamp * Copper Beaker * Thermometer * Measuring Cylinder * Alcohol Burners * Bunsen Burner * Electrical Balance * Stop Watch Diagram Method Firstly I will set up the equipment as shown in the diagram. I will then choose one spirit burner out of Methanol, Ethanol, Propanol or Butanol. I will then weigh the spirit burner on the electrical balance and note down the weight in grams (g). Then I will get the copper beaker and weigh it on the balance and note it down. I will also measure the height of the copper beaker above the bench I am working on. ...read more.


This is to make the results more accurate and incase I get any anomalous results. I am going to weigh the copper beaker and spirit burners to 2 d.p. to keep it more accurate. Fair Test To keep it a fair test I am going to use the same copper beaker, as if I used a bigger beaker it may change the time took to heat the water up. The only thing I will change is the spirit burner, as I am trying to find out which one is the best fuel. Results Below are the results tables of each alcohol burner, and the readings I got for each time I did the experiment. I have pu them in four separate tables, one for each alcohol. Methanol 1st time 2nd time 3rd time Mass of copper beaker (g) 46.8 46.8 46.8 Volume of Water 50ml 50ml 50ml Height of Beaker (cm) 8.5 8.5 8.5 Size of Flame (cm) ...read more.

But first I needed to work out the average of each attempts on each alcohol, this will be the result I put in my graph. To work out the average I worked out the difference between the weight of the burner before and after each experiment. I then added these 3 differences up, and then I divided them by 3. This got me the average. I then drew a bar chart and placed the results in this graph, so I could view them more clearly for evaluation. Evaluation The best fuel to use is the one, which uses little, so higher the difference the more fuel there is. The best fuel to use will have a low difference. ...read more.
