Anupma Raj-12i May 7, 2007 WHICH ALCOHOL IS THE BEST FEUL BETWEEN METHANOL, ETHANOL AND PROPANOL? INTRODUCTION: In this experiment I will determine the amount of heat energy involved in a chemical change. When an alcohol burns it produces carbon dioxide and water as products. Energy is also released in the reaction. I will be determining the amount of heat liberated when three alcohols burn, and compare their energy output, i.e. their heat of combustion. We will be using methanol CH3OH , ethanol C2H5OH , and propan-1-ol CH3CHOHCH3/C 3H 7OH. RESEARCH QUESTION: To investigate which alcohol gives out most energy per gram/mol/cm3 and hence, is the best fuel. HYPOTHESIS: I think that propan-1-ol will give out the most energy during combustion followed by ethanol and then methanol and hence, propan-1-ol will be the best fuel. During complete combustion of an alcohol, the energy is produced from formation of combustion products CO2 and H2O. Thus, Heat of...
