Gold And Silver Wealth Of Nations
1,156 wordsIn the first book of The Wealth of Nations, Adam Smith discusses the Variations in the Proportion between the respective Values of Gold and Silver. Throughout history, these two metals have been regarded as mints of significant value. Before mines were found in America, the difference in value between silver and gold was usually seen as proportionate, where one ounce of fine gold was considered equivalent to anywhere from ten to twelve ounces of fine silver. More recently, the values have change...

Cobalt Based Alloys Relevant Material Here Was Found Alloy
1,192 wordsThis paper will discuss the key properties of three categories of implant alloys; stainless steels, cobalt-based alloys, and titanium-based alloys, focusing on those properties which make the implant alloys ideal for skeletal implants. An additional focus of the paper will be on any disadvantages possessed by each group of implant alloys. Wood was probably the first bio implant, a sturdy, inert, and readily available material in the older days. But as mankind aged newer materials were discovered...

Hall Heroult Process Bauxite Mined Aluminum
1,057 words... s, and soils contain aluminum compounds, but aluminum can be made inexpensively only from bauxite. Bauxite is the name for any ore that has a large amount of aluminum hydroxide- a chemical combination of aluminum oxide and water. Aluminum oxide, also called alumina, is the compound from which aluminum is made. Most bauxite consists of 30 to 60 percent alumina and 12 to 30 percent water. It also contains iron oxide, silica, and titanium oxide. The color of bauxite depends chiefly on how much ...

Solid Waste Recycling Programs
587 wordsrecycling, the process of recovering and reusing waste products from household use, manufacturing, agriculture, and business and thereby reducing their burden on the environment. During World War I and World War II, shortages of essential materials led to collection drives for silk, rubber, and other commodities. In recent years the environmental benefits of recycling have become a major component of waste management programs. For many years direct recycling by producers of surplus and defective...

Specific Heat Boiling Point
1,047 wordsThe purpose of this lab was to determine the specific heat of two different metals. In order to do this, specific directions were executed in order to discover the specific heat. First, we needed to obtain and record the weight of the Styrofoam calorimeter cup. Next, we filled the cup 2 / 3 full with cool tap water and recorded the temperature of the water. After this was done, we filled a glass beaker half full with water and placed it on a hot plate in order to have the water reach boiling poi...

Effects Of Acid Acid Deposition
770 wordsAcid Rain is a type of air pollution, formed when oxides of sulfur and nitrogen combine with atmosphere moisture to yield sulfuric and nitric acids, which may then be carried long distances from a source before they are deposited by rain. This pollution may also be snow, fog, or a dry form of precipitation. Acid rain is currently a subject of great controversy because of widespread environmental damage for which it has been blamed, including eroding structures, injuring crops and forests, and th...

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...

Liquid Water Aquatic Life
655 wordsWhat would the world be like if solid water was denser than liquid water? Density is a property of matter. It is defined as the amount of material that fits in a given space. Denser objects are naturally heavier than objects that are less dense and of the same size. In the same manner that solid objects have density, liquids also have density. In that connection, water is denser than oil. If two objects of different densities come into contact, then the one that is less dense will float on it. T...

Acid Rain Sulfur Dioxide
1,127 wordsAcid rain is precipitation of higher than normal acidity. Manmade increases in the acidity of precipitation are traced mainly to the burning of coal, oil, and gas by heavy industry and electrical utilities. Burning these fuels releases sulfur and nitrogen oxides (Sox and Nox) to the atmosphere where they combine with water vapor to produce sulfuric acid (H 2 SO 4) and nitric acid (HNO 3). The acids in the atmosphere are carried and deposited on the earth s surface in the forms of rain, snow, and...

Carbon Monoxide 1 Percent
404 wordsCarbon Monoxide, chemical compound of carbon and oxygen with the formula CO. It is a colorless, odorless gas, about 3 percent lighter than air, and is poisonous to all warm-blooded animals and to many other forms of life. When inhaled it combines with hemoglobin in the blood, preventing absorption of oxygen and resulting in asphyxiation. Carbon monoxide is formed whenever carbon or substances containing carbon are burned with an insufficient air supply. Even when the amount of air is theoretical...
