The Aerodynamics of Future Electric and Hydrogen Fuel-Cell Cars Wilson Tong School of Aerospace‚ Mechanical and Manufacturing Engineering RMIT University‚ Melbourne‚ Australia ABSTRACT This document will investigates the influence of global warming and peak oil including the consequences that affect the vehicle industry. Much research and development have been done in recent years to either "electrified" or to implement fuel cell onto normal road vehicles. The use of fuel cell on

Stratford-upon-Avon. Analyzing this short story written by Arthur C. Clarke‚ one can conclude that he must enjoy writing about scientific breakthroughs and he utilizes vocabulary that is very different from most authors. The entire story is about a hydrogen bomb destroying the city of Stratford-upon-Avon. The story is told a few days after the incident. The story describes the state of the small town after the bomb was dropped on it. The bomb is destructive‚ there are no humans‚ animals or even dialogues

This experiment shows the effects of changing the pH level has on Catalase. As predicted‚ the farther away the pH levels got from the optimum pH (7.2)‚ the lower the reaction rate. At a pH of 7.2‚ the foam of the reaction measures 6cm. At a ph of 3 it measures 2.5 cm‚ at a pH of 5 it measures 2.75 cm‚ at ph 9 it measures 2.3 and at 11cm it measures 2cm. pH measures the hydrogen ion concentration of a substrate. By changing the pH of the catalase‚ the enzyme was denatured. Denaturing is the result

Hydrogen Fuel As An Alternative Energy Source To Replace Fossil Fuels Since the beginning of industry humans have been in search of fuel to power machines and generate energy. Fossil fuels‚ such as crude oil and coal‚ discovered beneath the Earth’s surface were found to be an excellent source of fuel. These fossil fuels are burnt in order to generate the energy required to complete various tasks. Many nations count on coal‚ oil and natural gas to supply most of their energy needs‚ but reliance

Purpose Since there are two possible oxidation numbers for the iron nails‚ by this experiment we will need to determine the actual oxidation number of the iron in this experiment. Hypothesis As said in the introduction there will be two possible decomposition reactions: Fe (Ⅱ) + CuCl2 (aq) → Cu + FeCl2 2Fe (Ш) + 3CuCl2 (aq) → 3Cu + 2FeCl2 We can measure the mass of the two iron nails‚ and the copper after the reaction. Thus‚ we can compare the ratio of the mole and the mass of iron and copper. Procedure

The Effects on Enzymes By Bailey Rose The Effects on Enzymes Bailey Rose 10/31/2011 Abstract In this lab exercise‚ the study of enzyme catalase‚ we viewed the breakdown of hydrogen peroxide into water and oxygen. The purpose was to isolate catalase from starch and measure the rate of activity under different conditions. Changes in temperature and pH along with Substrate Concentration and Enzyme Concentration were the conditions tested in the experiment. Our class performed

Effects of the Bottleneck and the Founders effect Cecil Smith GS102 Grantham University Online The bottleneck effect happens when something of a great devastation has happened‚ causing a great amount of people to lose their lives and leave behind very few people at the most. The bottleneck effect happens at random and can kill of a whole population and with it can also wipe out the gene pool by doing so. An example of the bottleneck effect would be something like a tsunami‚ or an earthquake‚ which

The Effect of Temperature on the Enzyme Catalase Stephen Francis Biology 183 Abstract This experiment was performed to determine the resultant effect of temperature change on the reaction between the enzyme catalase and hydrogen peroxide. This experiment was performed by measuring and comparing the amount of oxygen bubbles produced and the absorbance of the catalase and hydrogen peroxide solution over time at room temperature‚ 2°C‚ 50°C‚ and 60°C. The overall result of this experiment proved

Abstract The aim of this experiment was to investigate the effect of temperature on the enzyme catalase. The original research question was exploring the effect temperature would have on a yeast catalase reacting with hydrogen peroxide (H2O2). To address the latter question a series of experiments were conducted. The various temperatures experimented with were as follows: 22 degrees Celsius (room temperature)‚ 0 degrees Celsius (freezing)‚ 100 degrees Celsius (boiling)‚ and 37 degrees Celsius.
