- 10531: Nuclear Power: Cons
- ... up to 3 percent, which would add about 7000 fatal cancers per year to a world population of 4 billion." (Kaku, 82) Considering 7000 deaths out of 4 billion people, it seems like a very high price to pay for what can be currently done safely. Even coal, a very dirty fuel does not contribute to cancer as much as radioactive waste produced by fission. In fact, a child living in ...
- 10532: The Noble Gases
- ... by Morris W. Travers. Traces of it are found in natural gas,hot springs and volcanoes but most of it is in the atmosphere. It is used for incadesent lights and it is used in high speed photography. Xenon is the first noble to form compounds with another element. It is very heavy and extremely rare. It was discovered by Sir Walter Ramsey and Morris W. Travers. It is found in ...
- 10533: Mini-Research
- ... as a proton. NEUTRON- In 1932, James Chadwick detected the third of the basic parts of an atom. He showed that uncharged particles, or neutrons, are emitted when atoms of other elements are bombarded with high-velocity helium atoms with all electrons remored, or an alpha particle. Neutrons were determined to have a mass of 1.0087 amu. They are unstable outside of an atom and slowly degenerate to form protons ...
- 10534: Lead and The Environment
- ... Europe. In modern times, lead has found a wide range of uses, and world demand for lead and its products has steadily increased. Lead's usefulness stems from the metal's many desirable properties: softness, high density, low melting point, ability to block radiation, resistance to corrosion, readiness to form alloys and chemical compounds, and ease of recycling. Its versatility, as well as its physical and chemical properties, accounted for its ...
- 10535: Insulation
- ... 27-28.67 degrees Celsius) at the end of two hours of testing and the bag without insulation was only 19 degrees Celsius. The experimenter thinks this is because all clothes has insulation as a high priority and thermal underwear has insulation as its highest priority. The experimenter thinks an experimental error is he always took the temperatures in the same order. The difference in seconds could change the data by ...
- 10536: Ideal Gases vs. Real Gases
- ... lack the attractive forces which hold the particles back when they collide. Therefore, they collide with less force. The differences between ideal gases and real gases can be viewed most clearly when the pressure is high, the temperature is low, the gas particles are large, and when the gas particles excerpt strong attractive forces. Monoatomic gas molecules are much closer to ideal gases than other particles since their particles are so ...
- 10537: Gallium
- ... slowly oxidizes in moist air until a protective film forms, and it becomes passive in cold nitric acid. Gallium has been considered as a possible heat-exchange medium in nuclear reactors, although it has a high neutron cross section. Radioactive gallium-72 shows some promise in the study of bone cancer; a compound of this isotope is absorbed by the cancerous portion of the bone. The most common use of gallium ...
- 10538: Crash Course in Density
- ... course. In a few minutes, all four of the fuel pumps had failed. The worst possible news, they were out of fuel. In a few more minutes the engines stopped running, and all of the high tech instruments became useless. They realized that they could not even make it to Winnipeg. Their only chance was an abandoned to a abandoned Air Force airstrip. Unfortunately, the airstrip had been converted to a ...
- 10539: Asymmetric Epoxidation of Dihydronaphthalene with a Synthesized Jacobsen's Catalyst
- ... product. Additional product was either lost or unreacted when the air bleed tube was inserted, causing some product to splash out of the reaction flask. These experimental errors may very well have led to a high amount of impurities in Product 3, which would account for the difference between the experimental melting point and the literature value. The net percent yield for the synthesis of Jacobsen's catalyst was 1.9 ...
- 10540: Analysis of A Vapor Power Plant
- ... pressure of P4 equal to 100 kPa and P2 equal to 300 kPa would be optimal for cycle performance. Not only is net work maximized, but damage to system components is minimized by having a high steam quality in the turbine. For this, energy input to the system is sacrificed, however the net result is a more efficient and maintenance free power plant. 5.0 Conclusion The computer model of the ...
