To observe temperature change in Ethanol and Methanol

Extracts from this document...

Introduction

PLANNING Nasra Salah 10C Aim: To observe temperature change in Ethanol and Methanol. Introduction (scientific knowledge): ETHANOL Ethanol is an alcohol-based alternative fuel produced by fermenting and distilling starch crops that have been converted into simple sugars. Ethanol ("Alcohol") C2H5OH METHANOL Methanol (CH3OH) is an alcohol fuel. Today a process using natural gas as a feedstock produces most of the world's methanol. (CH3OH) also known as methyl alcohol or wood alcohol, it's a chemical compound with chemical formula (CH3OH). It is the simplest alcohol, and is a light, volatile, colourless, flammable, poisonous liquid that is used as an antifreeze, solvent, and fuel and as a denaturant for ethyl alcohol and it burns in air forming carbon dioxide and water. Nasra Salah 10C Prediction: I predict that Ethanol will be in a higher temperature than Methanol in the time given to investigate the two fuels. ...read more.

Middle

Equipment: Heat- prove mat, beehive stand, stripod, beaker, goggles, ethanol, methanol, timer, guaze. Method: 1.Measure out 50ml of water in a beaker. 2.Place on tripod stand over the fuel M/Ethanol. 3.Light the fuel and record the temperature rise for every minute for 10 minutes and record results on a table. 4.Repeat the above twice more. 5.Repeat the above for the fuel Ethanol. Observing Collecting the data: I collected the data by applying to the method with both Ethanol and Methanol. Then I added up all the 3 results and divided it by 3 because there were 3 results. The answers to the division sums are then the average temperature for each minute of the investigation. Nasra Salah 10C Safety: I have had to wear goggles at all times, keep my bag and other equipments out of the way so that it doesn't catch the flame of the M/ethanol. ...read more.

Conclusion

Improvements: Next time, I will try and stick to the safety rules and start my investigation earlier so that I won't run out of time.

    With regard to fuel, the main instruments of state policy include taxation and subsidisation. Diesel fuel duty has been steadily increasing by 8 to 9 % each year, where as tax on natural gas has gone in the opposite direction with largest reductions occurring in 1996 (25% cut)

    Flame spread is most rapid when it is directed vertically upward, and an increase in flame spread is directly proportional to increase in the angle of inclination. The reason for this behavior lies in the way in which the physical interaction between the flame and the un-burnt fuel changes as the orientation is varied.
