Ford Motor Company York New York
461 wordsPlato said, The appetites or the passions may gain control of him and refuse to obey the dictates of his highest part, reason or mind. (Frost 131) If this is so what was Ford Motor Company so hungry for in the early 1970 s to knowingly sell thousands of unsafe cars to its customers? Yes, we can all agree that the foreign automakers were taking a big chunk out of the American industry with its fuel-efficient compact cars. We can even understand the concept of Ford wanting to produce its own compa...

Rate Of Reaction Bunsen Burner
1,230 wordsInvestigate A Factor Which Affects the Rate Of Fermentation Of Yeast This experiment is investigating one of the factors which affects the rate of fermentation of yeast. Several factors affect the rate of reaction: &# 61656; Increasing the concentration. (See the lock and key theory. ) If the substrate (glucose) is increased, then there would be more keys for the locks, therefore an increase in reactant concentration leads to an increase in reaction rate. &# 61656; The surface area, the bigger t...

Rate Of Reaction Carbon Dioxide
1,229 words... onward sources, from a textbook, encyclopedia, and preliminary work that I have done in class. I have shown my results on a bar chart and a line graph. On the line graph, I have drawn a curve of best-fit. There were no anomalous results. From my results, and my graph, I have found out that as the temperature of the enzymes (yeast in this case) is increased, the rate of reaction speeds up. However, when the temperature reached a certain point, (about 40 degrees Celsius), the enzymes became de...

Extremely Important Everyday Life
484 wordsMomentum has an integral part in the field of physics. However, many people do not know the importance of momentum in everyday life or even recognize it. The truth is that we use momentum in just about every activity that involves motion. When we drive a car we use the principles of momentum to realize how much cushion space we need or how much stopping distance is needed when going a certain speed. Momentum is also extremely important when trying to understand collisions. Collisions occur every...

Lot Of Money Deaths Caused
1,222 wordsThere are many reasons why the United States should enact deer control laws. For example, one night I was coming back to Cowley, I swear I saw at least 15 to 20 deer run across the road in front of me. My proposal is that we should figure out what to do about the deer population. Here are some reasons why we should enact on the laws. Theres so many people dying or they are in serious accidents. The deer population has increased majorly in the last few years. These animals should be controlled fo...

Cellular Telephones Cell Phone
1,931 wordsBOSTON A driver chatting into a cell phone as the car whizzes down the road is becoming a more common sight in this age of telecommunications. State legislators and federal officials agree that the use of cellular telephones while driving poses a distraction which may lead to car accidents. But they acknowledge that little is being done to address the issue. "Anything that takes your eyes off the road is a hazard, " state Rep. Reed Hillman, R-Sturbridge, said.

2 H 2 O Carbon Monoxide
1,607 words1. State the five assumptions of the Kinetic-Molecular Theory of gases. a) Gases consist of large numbers of tiny particles. These particles, usually molecules or atoms, typically occupy a volume about 1000 times larger than occupied by the same number of particles in the liquid or solid state. Thus molecules of gases are much further apart than those of liquids or solids. Most of the volume occupied by a gas is empty space. This accounts for the lower density of gases compared to liquids and so...

Concentration And Reaction Rate
1,782 words... e light intensity the same throughout the entire experiment by working in the shade. Prediction: I predict that as concentration of thiosulphate increases so will reaction rate. Concentration of a reactant affects reaction rate because there are more frequent successful collisions. Assume a person has two chemicals x and y, which react when put together. If all input variables remained constant apart from concentration then fastest reaction rate possible would be to mix (assuming there isnt ...

I watched to see how fast Alka-Seltzer would react with different liquids. I changed the type of liquid from water to vinegar for some of the experiments. I also used one tablet that was solid and one that I had crushed up to see the differences. I changed the temperature with each new experiment, except when I was comparing and contrasting solid to ground up tablets. I always use...

Rate Of Reaction Hydrogen Bonding
2,165 wordsRESEARCH I know that Rennin is an enzyme, so before conducting this experiment I am first going to do some research into enzymes and their effects. 1. Enzymes Enzymes are large globular molecules of which the vast majority are protein in nature, though some, known as 'ribozyme's' are made of RNA. Enzymes have catalytic properties; in other words, they alter the rate of reaction without themselves undergoing a permanent change. Most chemical reactions require an initial input of energy, called ac...

H 2 O 2 O 2
828 wordsPurpose - The purpose of this lab is to use a chemical titration to measure and them calculate the rate of conversion of hydrogen peroxide (H 2 O 2) to water and oxygen gas using the enzyme catalase. Hypothesis - The rate of enzymatically-catalyzed reactions can be determined by taking time reactions at different time intervals. When the rates are plotted on a graph, the rate of the reaction is the slope of the linear portion of the curve. To determine a rate, any two points on the straight-line...

Permeable Membrane Semi Permeable
781 wordsOsmosis is the flow of water through a semi permeable membrane that blocks the transport of salts or other solutes through it. It is also defined as the net movement of water from an area of high concentration to a region of low concentration. Osmosis is a fundamental effect in all biological systems. When two water volumes are separated by a semi permeable membrane water will flow from the side of low solute concentration to the side of high solute concentration. If external pressure is applied...

Law Of Inertia Newton
1,582 wordsTwo cars are travelling down a highway at 100 km / h in opposite directions. Both drivers are tired from driving all day and cross over the yellow line and hit head on. Crash! The driver of car A has remained inside the car and has broken ribs due to hitting the steering wheel. The driver of car B however is on the hood of car A and is pronounced dead at the scene, cause of death, a severe case of disobeying the laws of physics. Although both cars were heading at the same velocity one driver end...

Kilometers In Diameter Mitral Valve
1,169 wordsReading Response Researchers have now concluded that a heart defect, called mitral valve prolapse is not as dangerous as it was previously pronounced. The defect is far less common and dangerous, only effecting about 5 percent of Americans. The syndrome, which is caused by the mitral valve flaps becoming elongated and floppy, letting blood flow backwards into the heart chamber. The defect may require surgery to prevent sudden death, stroke, heart failure, and abnormal heart rhythms that cause fa...
