Mountain Dew Water Vapor
1,257 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 a...

Ultraviolet Radiation Ozone Layer
1,027 wordsGreenhouse Effect On a bright, cool day, most people notice the sun's rays as feeling good on their skin. By nature, many of us even try to stay on the sunny side of the street while walking. The sun is 93 million miles away from earth and its energy travels to us in moving waves called radiation. The energy becomes heat, light and other energy too. Visible sunlight allows us to see the world around us, but there is invisible sunlight, too. These rays can't be seen, but some can be felt as heat....

Prevailing Winds Low Pressure
647 wordsWhy There Are Different Climates In Different Places Why Are There Different Climates Different Places The main factor that determines the climates of any place is its distance from the equator. This is because sun never rises high. Therefore the places close to the equator remains warm. Temperature typically decreases as altitude increases. At high altitudes the air is less dense, and it does not absorb and hold as much heat. On the average, the temperature drops about 3. 5 Fahrenheit for every...

Carbon Dioxide Common Type
505 wordsIs fire truly a living thing? It consumes fuel and oxygen, produces heat and waste, it grows and moves. Weather fire is alive or not, it is still dangerous, so you should always treat it with care. There are four main types of fires which are rated in class A, B, C and D. Knowing how to put particular fires out could save your property, someone's life, or your own life. In order to know how to put fires out, you must first know how one starts. For a fire to occur, there must be three things pres...

Billion Years Ago Million Years Ago
687 wordsThe Principle Events in the Evolution of the Earth's Atmosphere The literal translation of the word atmosphere is "sphere of vapors." The Earth's atmosphere is a protective sphere of vapors, or air that surrounds the Earth and provides it with a layer of insulation from the harmful rays of the sun. It is a vital part of the Earth, and has changed dramatically since the beginning of time. The earth's atmosphere has gradually changed since the Earth's birth approximately 4. 6 million years ago. In...

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...

2 O 2 Bodies Of Water
1,333 wordsAcid rain pollution comes in various forms. Whether its toxic waste, CFCs, or sewage, they are all hazardous to the earth. These can deplete the earth and its inhabitants of resources, causing a harmful change. A product of pollution is acid rain. We shall see that acidification is harmful to all forms of life. Acid rain is any form of precipitation that is polluted by sulphur dioxide (SO 2), and nitrogen oxides (NOX). This acid precipitation can be in the form of rain, snow, sleet, fog, or clou...

Solid State Lasers Beam Of Light
1,749 wordsL A S E R S Did you know that some laser beams are small enough and powerful enough to drill two hundred holes on a spot as tiny as the head of a pin? The first major advancement in laser development came in 1954. This was the year that Charles H. Townes, an American physicist, created a device that amplified microwaves. This device was actually called a maser at first, which was short for Microwave Amplification by Stimulated Emission of Radiation Masers. It produced microwaves of just one freq...

Gas Chromatography Data Collection
939 wordsGas Chromatography Purpose: The purpose of the gas chromatography lab is to find out how different substances interact with the surface of a solid. Chromatography is a separation technique that depends on the relative distribution of the components of a mixture between a mobile phase and a solid stationary phase. Chromatography measures the tendency of a substance to interact with the surface of a solid or to remain in a mobile phase. When doing a chromatography lab the mobile phase has to be a ...

Rise In Sea Level Carbon Dioxide
633 wordsThe global warming is caused by emissions of over 20 gases into the atmosphere. The major contributors are carbon dioxide (CO 2), ozone, methane, nitrous oxide and chlorofluorocarbons (CFCs). Although these gases are produced by many industrial processes, the major source is the burning of fossil fuels in boilers, furnaces and automobile engines. When released into the air in large quantities, these gases cause the earths atmosphere to warm by trapping the suns heat. Infrared radiation that woul...

Carbon Dioxide Methane Nitrous Oxide
705 wordsThe earth s climate is predicted to change because human activities are altering the chemical composition of the atmosphere through the buildup of greenhouse gases primarily carbon dioxide, methane, and nitrous oxide. The heat-trapping property of these gases is undisputed. Although uncertainty exists about exactly how earth s climate responds to these gases, global temperatures are rising. Energy from the sun drives the earth s weather and climate, and heats the earth s surface; in turn, the ea...

Pure Form Sodium Sodium Hydroxide Soda
393 wordsLife could not exist without compounds of sodium. These compounds hold water in body tissues, and a severe deficiency of sodium can cause death. Blood contains sodium compounds in solution. Sodium compounds are used in industry in the manufacture of chemicals and pharmaceuticals, in metallurgy, in sodium vapor lamps, and in the production of hundreds of every day products. One of the most common sodium compounds is table salt, or sodium chloride. In its pure form sodium is a silver-white, soft a...

Northern Hemisphere Food Shortage
875 wordsThe gray whale decline has been an eminent problem for many decades. There are numerous reasons for the gray whales to be in decline. Some of these reasons include the whale hunting that occurred in the mid 1860 s into the early 1870 s on the coast of California (Jones, pg. 173). There are, to this day, two countries that continue to ignore the whale moratorium (Busch, pg. 103). Another reason is the dead gray whales washing up on the shores of the West Coast, which is probably due to their food...

After Earth, Mars is the planet with the most hospitable climate in the solar system. So hospitable that it may once have inhabited primitive, bacteria-like life. Outflow channels and other geologic features provide extensive evidence that billions of years ago liquid water flowed on the surface of Mars. Continuing changes is an accomplishment in modern American technology and it gives the wor...

H 2 O Mass Spectrometer
531 wordsAMass Spectrometer Mass Spectrometer A mass spectrometer produces charged particles (ions) from the chemical substances that are to be analyzed. The mass spectrometer then uses electric and magnetic fields to measure the mass (weight) of the charged particles. There are many different kinds of mass spectrometers, but all use magnetic and / or electric fields to exert forces on the charged particles produced from the chemicals to be analyzed. A basic mass spectrometer consists of three parts: 1. ...
