Causes of Car Accidents Essays Causes of Car Accidents Essay Causes of Car Accidents Essay (NHTSA, auto-accident-resource. com). Among the car accidents, the teenage group is the only age group who is number of deaths is increasing instead of decreasing. Also, all the people are exposed to risk and actually every one of them has got car accident at least once that could have been easily prevented. There are many reasons car accidents happen such as drunken drivers, using cellular phones while driving, and teenage drivers. First reason is drinking and driving which is the leading cause of car accidents. Over 1. 1 million drivers were arrested in 2010 for driving under the influence of alcohol or narcotics, (Federal Bureau of Investigation, â€Å"Crime in the United States: 2010†, madd. org). Also,† drunk driving costs the United States $132 billion a year , (NHTS FARS data, 2012, madd. org). Driving while intoxicated is dangerous, because drinking increases your inhibitions and self-confidence but lower s your driving performance. In other words, alcohol impairs the decision-making ability of the brain. For example, when people get drunk, they do not even think they are drunk. They may feel like they can do anything. But they cannot. Many accidents occur because of drinking. These accidents involve mostly one car, but other people can be killed by drunk drivers. People have to be educated about drinking and driving, so they do not kill themselves or innocent people on the road. Second reason, using cell phones while driving causes car accidents. According to the Harvard Center for Risk Analysis, 2,600 people died in 2004 and 330,000 more were injured while using cell phones just before an accident. doityourself. com). When a cell phone is used while driving, it distracts the attention of the driver, leading to car accidents. While using a cell phone many people tend to miss traffic signals, because they are not really concentrating on driving. The process of dialing or answering the phone can make them lose control of the vehicle as well. Even though the driver is looking at the road, he or she can easily get distracted by the conversation. This can result in fatal accidents. Third reason of accidents on the road is teenage drivers. â€Å"2,739 teenagers died in car accidents in the United States during 2008 , (drivesteady. com). Some teenagers cause fatal accidents, because of immaturity and lack of experience. Teenagers are very impulsive. Although not intending to hurt anyone, they sometimes drive very aggressively. It is not difficult to find teenagers driving with one hand on the steering wheel, seat pushed back, and with loud music playing. In traffic they go wild, trying to seek attention. They underestimate the risk of what they are doing. All these acts result in serious consequences on the road. Many accidents of young drivers result from their own mistakes. In conclusion, many people do not realize that being intoxicated while driving, using cellular phones and teenage drivers may bring serious injuries to everybody. Some people may enjoy drinking without care until they get into car accident, which can even result in the deaths of many innocent people. The car accidents caused by these problems are really serious but preventable. If everybody tries to eliminate these problems by following the rules of the road, driving can be less dangerous, and we will not waste time on car accidents.

The Chemical Composition of White Gold

The Chemical Composition of White Gold White gold is a popular alternative to yellow gold, silver, or platinum. Some people prefer the silver color of white gold to the yellow color of normal gold, yet may find silver to be too soft or too easily tarnished or the cost of platinum to be prohibitive. While white gold contains varying amounts of gold, which is always yellow, it also contains one or more white metals to lighten its color and add strength and durability. The most common white metals that form the white gold alloy are nickel, palladium, platinum, and manganese. Sometimes copper, zinc or silver are added. However, copper and silver form undesirable colored oxides in the air or on the skin, so other metals are preferable. The purity of white gold is expressed in karats, the same as with yellow gold. The gold content is typically stamped into the metal (e.g., 10K, 18K). The Color of White Gold The properties of white gold, including its color, depend on its composition. Although most people think white gold is a shiny white metal, that color is actually from the rhodium metal plating that is applied to all white gold jewelry. Without the rhodium coating, white gold might be gray, dull brown, or even pale pink. Another coating that may be applied is a platinum alloy. Typically platinum is alloyed with iridium, ruthenium, or cobalt to increase its hardness. Platinum is naturally white. However, its more expensive than gold, so it may be electroplated onto a white gold ring to improve its appearance without dramatically increasing the price. White gold that contains a high percentage of nickel tends to be closest to a true white color. It has a faint ivory tone but is much whiter than pure gold.  Nickel white gold often does not require plating with rhodium for color, although the coating may be applied to reduce the incidence of skin reactions. Palladium white gold is another strong alloy that may be used without a coating. Palladium white gold has a faint gray tinge. Other gold alloys result in additional colors of gold, including red or rose, blue, and green. Allergies to White Gold White gold jewelry typically is made from a gold-palladium-silver alloy or gold-nickel-copper-zinc alloy. However, about one in eight people experience a reaction to the nickel-containing alloy, usually in the form of a skin rash. Most European jewelry manufacturers and some American jewelry manufacturers avoid nickel white gold since alloys made without nickel are less allergenic. The nickel alloy is most often encountered in older white gold jewelry and in some rings and pins, where the nickel produces a white gold that is strong enough to stand up to the wear and tear these pieces of jewelry experience. Maintaining the Plating on White Gold White gold jewelry that has a platinum or rhodium plating typically cant be resized because doing so would damage the coating. The plating on jewelry will scratch and wear over time. A jeweler can re-plate the item by removing any stones, buffing the metal, plating it, and returning the stones to their settings. Rhodium plating typically needs to be replaced every couple of years. It only takes a couple of hours to perform the process, at a cost of around $50 to $150.
