How Is Helium Produced
How Is Helium Produced? Production: Although Helium is one of the most common elements in the universe it is a rare gas on earth. It exists in the atmosphere in such small quantities (less than five parts per million) that recovering it from the air is uneconomical. Helium is produced as a by-product of the refining of natural gas, which is carried out on a commercial scale in the USA and Poland. In these areas natural gas contains a relatively high concentration of Helium which has accumulate...

Aerosol Spray Cans
Aerosol Spray Cans Spray cans produce an aerosol, the technical term for a very fine spray. They do this by means of a pressurized propellant, which is a liquid that boils at everyday temperatures. Inside the can, a layer of gaseous pressure increased, and eventually it becomes so high that boiling stops. when the nozzle is pressed, the gas pressure forces the product up the tube in the can and out of the nozzle in a spray or foam. The propellant may emerge as well but, now under less pressure, ...

Catalytic Converters
Catalytic Converters Notice when a vehicle drives by nowadays, that it is so much quieter than those loud oldies that pour out the blue smoke. Ever wonder just what is underneath a vehicle that makes the new ones so much cleaner. It is called a catalytic converter. The main function of a catalytic converter is to decrease pollution emitted from a vehicles exhaust. The concept behind this is to add a catalyst and force a reaction between the automobile's exhaust and oxygen in the converter. To se...

Chloroflourocarbons
Chloroflourocarbons Chloroflourocarbons were discovered in the 1920's by Thomas Midgley, an organic chemist at General Motors Corporation. He was looking for inert, non- toxic, non-flammable compounds with low boiling points that could be used as refrigerants. He found what he was looking for in the form of two compounds: dichlorodifluoromethane (CFC-12) and trichloromonoflouromethane (CFC-11). In both compounds, different amounts of chlorine and fluorine are combined with methane, which is a co...

Solar Cells
Solar Cells Solar cells today are mostly made of silicon, one of the most common elements on Earth. The crystalline silicon solar cell was one of the first types to be developed and it is still the most common type in use today. They do not pollute the atmosphere and they leave behind no harmful waste products. Photovoltaic cells work effectively even in cloudy weather and unlike solar heaters, are more efficient at low temperatures. They do their job silently and there are no moving parts to we...

Oxygen
Oxygen Oxygen, symbol O, colorless, odorless, tasteless, slightly magnetic gaseous element. On earth, oxygen is more abundant than any other element. Oxygen was discovered in 1774 by the British chemist Joseph Priestley and, independently, by the Swedish chemist Carl Wilhelm Scheele; it was shown to be an elemental gas by the French chemist Antoine Laurent Lavoisier in his classic experiments on combustion. Large amounts of oxygen are used in high-temperature welding torches, in which a mixture ...

Oxygen
Oxygen Oxygen and its compounds play a key role in many of the important processes of life and industry. Oxygen in the biosphere is essential in the processes of respiration and metabolism, the means by which animals derive the energy needed to sustain life. Furthermore, oxygen is the most abundant element at the surface of the Earth. In combined form it is found in ores, earths, rocks, and gemstones, as well as in all living organisms. Oxygen is a gaseous chemical element in Group VA of the per...

It has a resonance structure, and can be drawn in two different ways: O=O- O-O=O It is a bluish, explosive gas at room temperature, and has a boiling point of -119C. It has a melting point of -193C, and is a blue liquid. It's critical temperature and pressure are -12.1C and 53.8 atm, respectively. It has a pleasant odor in concentrations of less than 2 ppm, and is irritating and injurious in higher con...

The Ozone Layer
The Ozone Layer In environmental science the green house effect is a common term for the role water vapor; carbon dioxide and ozone play in keeping the earths surface warmer than it would normally be. The atmosphere is primarily transparent to infrared radiation from the sun, which is mostly absorbed by the earths surface. The earth being much cooler than the sun, remits radiation most strongly at infrared wavelengths. Water vapor, carbon dioxide and ozone then absorb much of this radiation an...

Photochemical Smog
Photochemical Smog Gifted Chemistry IB Alternative Assessment 1997 March 19 Historically, the term smog referred to a mixture of smoke and fog, hence the name smog. The industrial revolution has been the central cause for the increase in pollutants in the atmosphere over the last three centuries. Before 1950, the majority of this pollution was created from the burning of coal for energy generation, space heating, cooking, and transportation. Under the right conditions, the smoke and sulfur dioxi...

Greenhouse Effect
Greenhouse Effect When one starts a car or burns wood, the last thought on their mind is the consequences to these actions. Unfortunately, the daily dangers to earth are not widely know. Due to the constant change of society, this planet must cope with various problems. One of the most important ecological structures is the ozone layer. The same shield that protects us from the suns deadly radiation, can also act as a blanket engulfing us in heat. This situation is know as the greenhouse effect...

A Short Overview Of Hurricanes
A Short Overview Of Hurricanes Hurricanes are powerful atmospheric vortices that are intermediate in size. Hurricanes are unique and powerful weather systems. The word hurricane comes from a Caribbean word meaning big wind. Views of hurricanes can be seen from a satellite positioned thousands of miles above the earth. Hurricanes originate as tropical disturbances over warm oceans with trade winds. The tropical turbances intensify into tropical depressions, and eventually into a tropical stor...

Carbon Dioxide In Beverages
Carbon Dioxide In Beverages Carbon dioxide is a colorless gas, it has a small but sharp odor and a slightly sour taste. Each molecule of carbon dioxide consists of one atom of carbon and two atoms of oxygen. Its chemical formula is CO2. Carbon Dioxide is about 1.5 times heavier than air. The specific volume at atmospheric pressure (101.3 kilopascals) and 70 F (21 C) is 8.74 ft3/lb. Under normal conditions it remains stable, inert and non-toxic. To liquefy CO2 it must be under 300 pound per inch ...

Depletion Of The Ozone Layer
Depletion Of The Ozone Layer The ozone layer diminishes more each year. As the area of polar ozone depletion (commonly called the ozone hole) gets larger, additional ultraviolet rays are allowed to pass through. These rays cause cancer, cataracts, and lowered immunity to diseases.1 What causes the depletion of the ozone layer? In 1970, Crutzen first showed that nitrogen oxides produced by decaying nitrous oxide from soil-borne microbes react catalytically with ozone hastening its depletion. His ...

Effects of Acid Rain
Effects of Acid Rain How Acid Rain Develops, Spreads, and Destroys Acid rain is environmentally damaging rainfall that occurs after fossil fuels burn, releasing nitrogen and sulphur oxides into the atmosphere. Acid rain, simply stated, increases the acidity level of waterways because these nitrogen and sulphur oxides combine with the airs normal rainfall. Acid rain is a silent threat because its effects, although slow, are cumulative. This analysis explains the cause, the distribution cycle, an...

Enviormental Affects Of Global Warming
Enviormental Affects Of Global Warming Environmental effects of global warming The greenhouse effect and global warming are issues that are talked about by geologists all the time. The greenhouse effect is a natural process that keeps the earth at temperatures that are livable. Energy from the sun warms the earth when its heat rays are absorbed by greenhouse gasses and become trapped in the atmosphere. Some of the most common greenhouse gasses are water vapor, carbon dioxide, and methane. If the...

Global Warming
Global Warming Reptiles Enjoyed Warm Arctic (Global Warming) An article written by ABC News writer Kenneth Chang discusses the change in climate of the arctic from ninety million years ago. Seven hundred miles from the North Pole, lies an island called Axel Heiberg, a barren land that scientists have dug up fossil bones of a cold-blooded reptile known as a champsosaur. How does this happen in an arctic, freezing land? How does a reptile that needs the warmth of the sun to survive, live in a frig...

Greenhouse Effect 2
Greenhouse Effect 2 The greenhouse effect occurs when gases such as methane, carbon dioxide, nitrogen oxide and CFCs trap heat in the atmosphere by acting as a pane of glass in a car. The glass lets the sun light in to make heat but when the heat tries to get out the gases absorb the heat. Holding this heat in causes heat waves, droughts and climate changes which could alter our way of living. The main gases that cause the greenhouse effect are water vapor, carbon dioxide (CO2), and methane whic...

Computers Hackers And Phreaks
Computers, Hackers, And Phreaks The Internet is a wondrous place. Practically anything you could ever want is available on the Net. It's like a big city, it has the highly prestigious areas, and the sex-ridden slums (Mitchell). It has the upstanding citizens, and it has the criminals. On the Net, crime is more abundant than in a large city, though, mainly because of the difficulties in tracking and prosecuting offenders. Even from its beginnings, the Internet has always been a battlefield betwee...

Hurrican Report
Hurrican Report Hurricanes can be caused by many forces acting upon one anotherThe hurricane must form over ocean water that is 26.5* C. Hurricanes draw their energy from warm waters. The atmosphere must be unstable. The cyclone has to be at most 500 kilometers from the equator, because the Coriolis force is not present there. The Coriolis Force makes the cyclone spiral and maintain its low pressure. A high pressure area must be present above the storm, which pushes away the air that is rising ...

An Analysis Of The Jehovah's Witnesses' Religion
An Analysis Of The Jehovah's Witnesses' Religion When the name of Jehovah's witness arises, most of the public of differing religions, a picture of an overly nice person or group of people all dressed in suits and nice clothes, arrive at your door and offer a sampling of pamphlets, (large or small). To most of the general public, the religion is a far cry from Christianity, but this is untrue, as a visit to one of the services that the congregation provides. Upon arriving at the building Kingdom...

Christmas History
Christmas History The word Christmas comes from the old English Cristes maesse meaning Christ's Mass. The Holiday celebrates the birth of Jesus Christ. The actual birthday of Jesus is not known; therefore, the early Church Fathers in the 4th century fixed the day around the old Roman Saturnalia festival (17 - 21 December), a traditional pagan festivity. The first mention of the birthday of Jesus is from the year 354 AD. Gradually all Christian churches, except Armenians who celebrate Christmas...

The One Truth of Reality
The One Truth of Reality The one single truth of reality is not measured or distinguished -- it is the ultimate paradox. The journey by which one achieves this truth can be a journey of increasing realizations of paradoxes, and finally, freedom from the bubble of limitation of a mind that would perceive such paradoxes as paradoxes in the first place. Truth is the same as spiritual feeling. Of spiritual perception. Of clear perception. Of freedom of the mind. Freedom of the soul. Freedom of the H...
