...Flexible PVC ... sometimes called simply "vinyl" ... has additives like octyl phthalate (which contains carbon, hydrogen, and oxygen) that keep the polymer swollen and flexible. What elements are electrical wiring made out of? Answer: Almost all electrical wiring is made of copper. For larger sizes to keep the cost of the installation down the wire used is aluminum. Sometimes the copper wire is tinned with solder, and sometimes there is some silver in it. ==== For over 100 years utility companies have been using aluminum wire in their power grids. It has advantages over copper wire in that it is lighter, more flexible, and less expensive. Aluminium wire in power grid applications was very successful and is still used today. Wiring in homes and buildings is another matter. In the '60s when the price of copper skyrocketed, aluminum wire was manufactured in sizes small enough to be used in homes. Aluminium wire requires a larger wire gauge than copper to carry the same current. For example, a standard 15 A branch circuit wired with No. 14 gauge copper requires No. 12 gauge aluminum. When first used in branch circuit wiring, aluminum wire was not installed any differently than copper, and many of these connections failed due to bad connection techniques and dissimilar metals. These connection failures generated heat under electrical load and resulted in overheated connections. Most metals oxidize when exposed to air. Aluminium oxide is an electrical insulator...

...which it has the ability to conduct heat and electricity. The metals comprise about two thirds of the known elements. Some metals, including copper, tin, iron, lead, gold, silver, and mercury, have been around for many years, so long, that they were known to people in ancient times. Copper is probably the oldest known metal, known to humans. Metals differ so widely in hardness, tensile strength, density, and melting point that a definite line of distinction between them and the nonmetals cannot be drawn. The hardest elemental metal is chromium with the softest being cesium. Most metals are malleable, but gold, silver, copper, tin, and aluminum are extremely so. Some metals exhibiting great tensile strength are copper, iron, and platinum. In the heavy metal category, beginning with the most dense, are osmium, iridium, platinum, gold, tungsten, uranium, tantalum, mercury, hafnium, lead, and silver. When it comes to industrial uses, the melting points of the metals are important. Tungsten is the hardest metal known to man, and it only melts at extremely high temperatures that reach over 3,300 degrees Celsius, while cesium has a melting point of 28.5 degrees Celsius. The best metallic conductor of electricity is silver. Copper, gold, and aluminum follow in that order. All metals are relatively good conductors of heat with silver, copper, and aluminum at the top of the list. The radioactive metal uranium is used in reactor piles to generate steam and electric power. Plutonium,...

...2014 Problem 1 The current price of silver is $30.00 per ounce. The storage costs are $0.35 per ounce per quarter payable at the beginning of each quarter. The risk-free rate of interest is 10 percent per annum with continuous compounding for all maturities. Jaime has just entered into a forward contract to buy 10,000 ounces of silver in six-months. a) What is the present value of the storage cost? b) What are the six-month forward price and the value of Jaime’s forward contract? c) Three months later the spot price of silver is 27.50 and the risk-free rate of interest is still 10 percent per annum with continuous compounding for all maturities. What is the value of Jaime’s forward contract? d) Explain why the forward price of silver can be calculated from its spot price and other observable variables whereas the forward price of copper cannot. a) The present value of the storage costs: b) ( ) ( ) The initial value of a forward contract is zero. c) The value of Jaime’s contract is d) Silver is an investment asset. If the forward price is too high, investors will find it profitable to hold more silver and short forward contracts. If the forward price is too low, investors will find it profitable to sell more silver and long forward contracts. Copper is a consumption asset. If forward price is too high, a strategy of buying copper and short forward contracts works. However, because investors generally hold copper for consumption, they are reluctant ...

Some of the great things he did include, all his work as a gold and silversmith, the many rides he took to spread information about the British, and his work with the sons of liberty. Paul is recognized for many things, but is his work with silver and gold isn't as popular of a fact as some others. He started learning how to do was make things out of gold and silver at the young age of 12. By 1758, Paul Revere had gotten recognized as a master goldsmith. Shortly after that, he made the famous liberty bowl and the engraving of the Boston Massacre. After the war was over he continued making things, like the first church bell, copper spikes and bolts for a warship, a silver tea set, the first copper rolling mill, and copper sheeting for the state house of Boston. All of these things are great accomplishments, and deserve a lot of recognition....

...All About Peru: Natural Resources, Plants, and Animals Peru has many wonders of the world! It has natural resources that can be primarily found there along with many kinds of plants and animals! There are many natural resources in Peru. Some of them are gold, copper, and silver. All those natural resources are used mainly for value. Each one has its own value. A 1943 to 1965 gold Peruvian gold coin is roughly about a dollar in America. If the gold coin has perfect condition it will cost 15 dollars. Of course there are different type of coins and that is the case here with gold coins. A different gold coin that is 50 soles in Peru, from 1950 to 1970, is worth about 959 dollars today! An 1859 silver coin in Peru costs 25 dollars here. Lastly, but not least, copper coins. Peruvians used copper coins for over 100 years, their value was un centavo (one cent) or dos cenatvos (two cents). Today an averaged use one cent Peruvian copper coin is worth three dollars here in America. A two cent copper coin with the same condition as the one cent is worth four dollars here. Peruvians don’t stop there, there is still more fantastic things in Peru. Moving on to the topic of plants, there are many different kinds of plants that can be found in Peru! Some of them include, Rosa Sisa, San Pedro Cactus, Huacatay, and Sangre de Drago. The Rosa Sisa, often referred to as Flor De Meurto in Mexico, is a plant what is thought to have mystical powers. It is featured in funeral, gravesites, and on...

It was initially worth 16 reales. When different reales were introduced, the escudo became worth 16 reales de plata in 1642, then 16 reales de plata fuerte or 40 reales de vellón from 1737. Coins[edit] Gold coins were issued in denominations of ½, 1, 2, 4 and 8 escudos, with the 2 escudos coin known as the doubloon. Between 1809 and 1849, coins denominated as 80, 160 and 320 reales (de vellon) were issued, equivalent, in gold content and value, to the 2, 4 and 8 escudo coins. Most were minted in Madrid, marked with a superscripted M or in Seville bearing an S below and left of the Royal Coat of Arms. The mintmaster's initials appeared on the opposite side. ------------------------------------------------- Silver escudo[edit] The second escudo was the currency of Spain between 1864 and 1869. It was subdivided into 100 céntimos de escudo. The escudo replaced the real at a rate of 10 reales = 1 escudo. It was itself replaced by the peseta, at a rate of 2½ pesetas = 1 escudo, when Spain joined the Latin Monetary Union. The later silver escudo was worth one quarter of the earlier, gold escudo.

...economy Numismatics is the scientific study of money and its history in all its varied forms. Many items have been used as commodity money such as naturally scarce precious metals, cowry shells, barley, beads etc., as well as many other things that are thought of as having value. Modern money (and most ancient money) is essentially a token — in other words, an abstraction. Paper currency is perhaps the most common type of physical money today. However, objects of gold or silver present many of money's essential properties. Non-monetary exchange: barter and gift Contrary to popular conception, there is no evidence of a society or economy that relied primarily on barter. Instead, non-monetary societies operated largely along the principles of gift economics. When barter did in fact occur, it was usually between either complete strangers or would-be enemies. In a gift economy, valuable goods and services are regularly given without any explicit agreement for immediate or future rewards (i.e. there is no formal quid pro quo).[3]Ideally, simultaneous or recurring giving serves to circulate and redistribute valuables within the community. There are various social theories concerning gift economies. Some consider the gifts to be a form of reciprocal altruism. Another interpretation is that social status is awarded in return for the 'gifts'.[4] Consider for example, the sharing of food in some hunter-gatherer societies, where food-sharing is a safeguard against the...

...specifically into the mining industry. Peru has an enormous economic strength in the form of multiple mineral deposits and is currently ranked 4th in the world. It currently occupies 7th place among the top 10 leading mineral producing countries, with an estimated production value of US$ 27,063 million. The primary competitive advantage for Peruvian mining is its diversification of minerals being produced: copper, gold, silver, lead, zinc, tin, molybdenum, iron, cadmium, mercury, selenium, indium and other metals. It is the region’s top producer of zinc, tin, lead and gold, and occupies second place in the production of copper, silver, molybdenum, mercury, selenium, cadmium and phosphoric rock. Currently, Peru has a sufficient reserve of minerals to generate a constant flow of metal production for several decades. The high rates of production have attracted a large amount of inbound investment into Peru's mining sector. An estimated US$ 59.5 billion is expected to flow into the country over the next few years. New mines and expansion projects are expected to more than double its copper production by 2016. The Peruvian economy was revived by the resurgence of the mining sector and has been one of the key drivers behind the company’s stellar growth records. However this...

...when rocks containing metal were heated with charcoal in fireplaces. A chemical reaction called reduction would have taken place which freed the metal from its ore. The same reaction is still used in blast furnaces to extract iron. The first metals The first metals worked by people were copper, gold and silver, probably because these are found as pure metals. In about 3500 BC, the Sumerians learned how to make bronze by combining copper and tin. Bronze is stronger than the pure metals. Iron was not used until around 1350 BC, probably because it needs much higher temperatures to separate it from its compounds. New metals Up until 1735 AD, the only known metals were copper, silver, gold, iron, mercury, tin, zinc, bismuth, antimony and lead. Aluminium was discovered in 1825. Now scientists can create new metal elements, such as mendelevium, by bombarding atoms with electrons in a particle accelerator, which is a type of nuclear reactor. The atoms break apart under the bombardment, enabling scientists to get a glimpse of their structure.
