Using ethanol as an alternate fuel‚ or fuel extender includes a heterogenous agglomeration of advantages and disadvantages. On cars: ethanol is preferable to lead as an octane booster. A 10% addition of ethanol to petrol is more effective than lead at boosting octane rating (+2.5) and making car run smoother. It’s cheaper than lead‚ and ethanol-blended fuels leave no gummy deposits‚ thus keeps engine clean. Although a minimal 10% ethanol blend should be compatible with internal combustion engines

Separation processes by using the application of membrane have become highly demand in various industries. In this newly separation process ‚ the membrane function as a semi-permeable barrier and the separation process occur by the membrane controlling the rate of movement of various molecules between two liquid phases ‚ two gas phases or a mixture of a gas phase and liquid phase. In industries‚ many companies have high demand on both quality and quantity of water for production. Membrane process can be used

Investigate factors affecting cell membrane permeability in beetroot. Research Question: How does variation in temperature affect the permeability of cell membranes? Background Information: In this investigation I will want to identify how variations in temperature effect the permeability through the use of a beetroot. I predict that as the temperature of the water increases so will the dispersion of the pigment. Independent Variable: The temperature of water will be increased in increments of 10oC

experiments will be conducted to evaluate ethanol as a fuel‚ the experiments are Fermentation and Calorimetry. Fermentation will find the best combination of sugar and yeast for optimum ethanol production and the Calorimetry experiments test ethanol against other alcohols and fuels to see how it matches up in terms of energy production. Fermentation shows glucose and baker’s yeast as the fastest producers of ethanol and the calorimetry proves that ethanol and other alcohols produce more heat energy

Aim How temperature affects membranes: investigating the effect temperature has on Beta vulgaris membranes when submerged in a range of different temperatures for one minute. Background Information A cell membrane is made up of a phospholipid bilayer formed by phospholipids that have a hydrophilic head and a hydrophobic tail. The phospholipids arrange themselves in order that the heads are exposed to water and the tails are not thus forming the bilayer. When the temperature increases molecules

Etiquette and Dealing with Disruption The tone of the classroom interaction has a significant impact on the educational environment. These days‚ the pervasive use of devices such as cell phones and the fact that some students may be unaware of University behavioral standards or the impact of their actions on others can lead to repeated distractions and interruptions. University of California Standards of Conduct for Students provide that students may be disciplined for "disruption or obstruction" of teaching

Heat of Mixing: Ethanol and Water Abstract The temperature change when known amounts of water and ethanol were mixed was determined to see the enthalpy change in an isothermal and isobaric environment. Agreeable data was found compared to similar experiments. As the mole fraction increased of the solution so did the enthalpy until a certain limit of about 0.32. Since water’s structure and unique properties affect many aspects of a solution‚ the solutions enthalpy’s decreased at a certain time
