... wool in the alcohols (not at the same time) and heated up the beaker of water with it until it went out. We had the starting temperature of the water before we did it and measured it when the flame had gone out. We decided to use 2mls of alcohol and 50mls of water. We chose to use these amounts because in our preliminary work we used 5mls of fuel, this took too long to burn. We also used 100mls of water and this took to long to heat up making our results un varied. I predict that Butan-1-ol will make the biggest temperature change because it has more bonds than both of the propanols. I think it will make more heat than Butan-2-ol because of the way the (OH) bond is arranged. If a (H) is on the end bond then it may be broken easier making more heat ...
