Prediction: I think methanol will have a higher temperature than ethanol because
Fair test: The test was fair because the amount of water and temperature for both experiments were the same. The height of the flame was also the same and we timed each experiment for 10 minutes. We used the same equipment for both experiment.
Safety: To make the experiment safe we tied back long hair, put on our goggles and cleared the space in front of us.
Equipment: The equipment we used were: beehive stands, tripod, gauze mat, timer, thermometer, beaker, goggles and heat proof mat
Method: 50ml of water at room temperature was poured into the beaker. The beaker was placed on a tripod which was on a gauze mat. The fuel was then lit and we used a thermometer to measure the temperature every minute. The experiment was repeated three times. Both fuels were used.
We recorded the data in two tables; one for ethanol and another for methanol. We used a calculator to work out the average temperature. The information was then used to make a graph.
The graph showed that ethanol gave more energy than methanol because it has more bonds.
Improvement: I think that I could improve this more by researching methanol and ethanol’s backgrounds before I start the experiment.
