# Investigating the Burning of Fuel

Extracts from this document...

Introduction

Investigating the Burning of Fuel In this experiment I will be burning some alcohols to heat a tin of water and the aim of this experiment is to find out which alcohol gives out the most energy with the least amount of fuel. The fuels that I am going to experiment with are: Butanol, Methanol, Ethanol and Propanol. Method- To start with I will weigh each fuel with its lid on; this is so nothing can spill or evaporate from the container in which the alcohol is. Then I will take one of the fuels that I have weighed and light the wick, I will then put it underneath the apparatus, which I previously set up. The alcohol will put underneath a tin filled with 120cm3 of water. I will then heat the water until it reaches 450C. I will then weigh the alcohol again with the lid on and I will write down the results of the before and after temperature. ...read more.

Conclusion

+ (4x12) + 16= 74g per mole O=16 Propanol H=1 C=12 (8x1) + (3x12) + 16= 60g per mole O=16 Methanol H=1 C=12 (4x1) + 12 + 16= 32g per mole O=16 Ethanol H=1 C=12 (6x1) + (2x12) + 16= 46g per mole O=16 Evaluation The results I achieved from this experiment were reliable, but there are some ways I could have improved the experiment to get better results. * There were a few windows open making the flame go out a few times, I shut them during the experiment. But if I was going to do the experiment again I would make sure all of the windows were shut to start with. * The wicks of all the alcohols had different lengths making some of the flames closer to the bottom of the tin. Another way of improving the experiment is to insulate the sides of the tin or cover the top to stop heat loss. ?? ?? ?? ?? Holly Mitchell 1 ...read more.

this will be used to hold the water, copper is used because it is a very good conductor of heat and will transfer more energy from the combustion to the water than other less good conductors. The bottom of the can has been painted black to absorb more heat through radiation.

Also 4cm was slightly too near so I chose 5cm as a reasonable distance. So from this I will be timing each experiment for two minutes with a 150ml of water in the can at a height of 5cm. I also performed another preliminary experiment, testing the use of blocks (bench mats surrounding the burner and tin can)

After further research on the subject I have found the formula that will allow me to calculate the average energy given out by the fuels. The correct formula is: Energy = Mass of water x 4.2 x Rise in Temperature The value 4.2 used here is the specific heat capacity of water, which is in kj0C.
