Effects Of Acid Rain Sulfur Dioxide And Nitrogen
3,730 wordsWhat is acid rain? Acid rain is the term for pollution caused when sulfur and nitrogen dioxides combine with atmospheric moisture. The term 'acid rain' is slightly misleading, and would be more accurate if deemed 'enhanced acid rain', as rain occurs acidic naturally. Acidity is measured on what is know as the pH scale. Fourteen is the most basic, seven is the most neutral, and zero is the most acidic. Pure rain has a pH level of 7, which is exactly neutral. The acidity of rain is determined by t...

Niels Bohr Model Of The Hydrogen Atom
365 wordsNiels Bohr's model of the hydrogen atom, was the primary reason for the understanding of energy levels. Bohr was able to explain the bright line spectrum of hydrogen. Sparked by the recent discovery of the diffraction patterns, scientists believed electrons could be described as waves. Bohr hypothesized that energy is being added to the hydrogen gas in the electricity form, and then leaving the gas in the form of light. He figured the light rays to be quantized, meaning only certain frequencies ...

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...

Combustion Engine Internal Combustion
561 wordsIn the past decade there has been a great deal of worrying about what will happen when the worlds oil supply becomes depleted. The main reason for concern is that almost all of the automobiles in use now require an oil based gasoline to run their internal-combustion engines. In the next few decades it is predicted that all of the worlds oil will have already been mined, and combustion engines will be unable to function. For this reason many companies such as Ford, Mercedes-Benz, Chrysler, Toyota...

Life On Earth H 2 O
726 wordsThe first thing water reminds us of is the clear liquid in our water bottles. However, water is more than a normal substance. Water is the beginning and the continual of life on earth. Because of its many unique properties, water was able to start life on our planet. The simple structure of H 2 O is the source of all water's properties. With two hydrogen atoms sticking to an oxygen atom in a tetrahedron shape, water is considered as a polar molecule. Because oxygen is very electronegative, it pu...

Break Even Analysis Fuel Tank
1,326 words... fe working of the engine. This was manufactured in house by the fabrication unit. o The fuel tank of the car was very big in size. Therefore a fuel tank was required for holding compressed hydrogen, which would consume less volume and space. This was possible by making the fuel tank of special alloy metal, which was made in the fabrication workshop itself. o The fuel stations had to be set up across the country. This required Volkswagen to set up hydrogen stations, which would attract more s...

Hydrogen Peroxide Degrees Celsius
539 wordsCatalase Which Is Found In The Liver' Introduction: Enzymes are biological catalysts. They speed up the chemical reactions which go on inside living things. Without them the reactions would be so slow that life would grind to a halt. Enzymes work by when a substrate molecule bumps into a molecule of the right enzyme, it fits into a depression on the surface of the enzyme molecule. This depression is called the active site. The reaction then takes place and the molecules of product leave the acti...

The origin of all life can be traced back to the water in the Earths precambrian seas. Water is also the universal solvent. It reacts with more elements and compounds than any other substance known to man. Water is a polar molecule made up of on atom of hydrogen and two atoms of oxygen. It is attracted to itsel...

Second Law Of Thermodynamics Existence Of God
1,625 wordsDescription for the existance of God The existence of God is a subject that has occupied schools of philosophy and theology for thousands of years. Most of the time, these debates have revolved around all kinds of assumptions and definitions. Philosophers will spend a lifetime arguing about the meaning of a word and never really get there. One is reminded of the college student who was asked how his philosophy class was going. He replied that they had not done much because when the teacher tried...

Water Vapor Petroleum Products
850 wordsWhy are we as Americans so afraid to change? Even if it is a change for the better? The world has been using oil coal and other petroleum products to power just about everything that moves for the last 150 years. Yet most cars in the United States only get 10 - 20 miles a gallon and even the good ones can get only a petty 20 - 50 miles a gallon. So why do we put up with the inefficiency when there are far better alternatives out there? Such as hydrogen, which was discovered hundreds of years ago...

1,319 wordsCount Ferdinand Von Zeppelin and his crew operated their first airship nearly one hundred years ago. Airships are big controllable balloons, also known as dirigibles. Therefore three classes of airships, rigid, nonrigid and semirigid. Rigid airships (zeppelins) use framework in the interior to keep their shape. Semirigid airships are a combination of framework and gas pressure to maintain their shape. Nonrigid airships (blimps) rely solely on air pressure to keep their form. They are all propell...

Force Of Gravity White Dwarf
2,676 wordsAlthough they are tiny in size, white dwarfs have played a great role in astronomy. These compact stars are very different from familiar objects like our sun. They also pose a seemingly endless series of puzzles, whose solutions provide new insights into many areas of physics and astronomy. To unravel a wide variety of phenomena such as cataclysmic variables (novae, dwarf novae), planetary nebulae, and some types of supernova, we have to understand white dwarfs. These stars may even hold clues t...
