From the experimental data and through its analysis‚ the enthalpy of combustion for the five alcohols were determined; methanol‚ ethanol‚ propanol‚ butanol‚ and pentanol. As the line of best fit in the graph suggests‚ the enthalpy of combustion increased as the sizes of the molecules increased. This was predicted in the hypothesis and proves it to be correct. As seen on the graph‚ the enthalpy of combustion increases from 140kJ/mol for methanol‚ which has the smallest molecular mass‚ to 530kJ/mol

Today‚ automobile manufacturers and DOE continue to work on hydrogen-powered ICEs. | Hydrogen/natural gas fueling (HYTEST fuel) of Ford Ranger‚ FSEC H2 Lab (Photo: S. Spencer) | There are four basic issues regarding hydrogen-fueled engines and vehicles: engine backfire and susceptibility of hydrogen to surface ignition‚ somewhat reduced engine power‚ high nitric oxide (NOx) emissions‚ and the problem of on-board storage of the fuel and safety.

Alternative Fuels for Cars Automobiles are considered one of the largest contributors to climate change – only preceded by the effect of fossil fuel power generation plants [1]. This means that the automobile industry is under a lot of pressure to cut down on carbon emissions globally by finding alternative fuels for cars. Moreover‚ as we approach peak oil [2]‚ the availability of conventional automobile fuels will reduce drastically causing an exponential rise in fuel prices [2]‚ a fact that

Alcohol Abuse By: Rian Geraldine S. Alberto Alcohol • • • • Alcohol is a drink containing ethanol It is a lipid that is highly water soluble A psychoactive drug that has a depressant effect. Distribution: Ethanol is distributed equally in all body tissue according to water content. • Metabolism: A healthy body can metabolize 15ml of alcohol/hour • Alcohol is metabolized by the liver but 10% is excreted unchanged in the breath‚ sweat and the urine Metabolism of alcohol Alcohol Aldehyde
