Daniel Osherow ENGR 1301 5 December 2012 Copper Wire Sizes (EE) The diameter of a copper wire is measured by using a system called the American Wire Gauge also known as AWG. This system has predominantly been used in the United States and Canada since 1857. Using this measurement the cross-sectional area of a gauge is able to be found. We then use this area to determine the wires current carrying capacity. The gauge numbers for wire and diameter values work inversely‚ as when one increases the

examine the extent to which the temperature and presence of common ions affect the amount of copper sulphate salt that can dissolve in 100 grams of water until it reaches saturation. In order to achieve the aims of this experiment‚ a methodical approach is taken to measure solubility of the salt at three different temperatures and then construct a solubility curve for copper sulphate. Additionally‚ copper sulphate is reacted with sodium hydroxide to investigate further the effect of common ions on

The primary advantage of a corporate form of business is that a corporation is a stand-alone entity‚ which means you are not personally liable for the assets and debts of the business. Incorporating protects your personal assets from lawsuits‚ debt collection and other business issues that can arise. The stand-alone entity also separates tax liabilities‚ which is another advantage. This means that the corporation’s taxes are separate from your personal tax liabilities. As a business

The discovery of copper does not have an exact date. Copper is said to be a prehistoric element. This element was said to be first discovered around 8000BC. The ancient civilizations started to take the copper out of the ore they found around 4000BC. This is when copper started to be put to good use. Early civilizations discovered that copper is malleable and is sharp. They realized they could make copper into tools and weapons. This was easier than the stone that they were originally using. This

1 Determination of Empirical Formula: Preparation of a Copper Sulphide. Aim The aim of the experiment was to determine the empirical formula of sulphide of copper and to make sure that an amount of copper metal reacted with elemental sulphur‚ Eq. 1. To be able to calculate the empirical formula of copper sulphide‚ the mass (grams) of copper has to be known and the mass (grams) of copper sulphide after the reaction. Copper‚ chemical formula Cu‚ is a known metal with a red-brown

experiment‚ we were trying to see whether copper‚ after a chain of chemical reactions‚ will revert back to its elemental form. Procedure: First‚ I added nitric acid with copper in a beaker‚ which turned into a copper nitrate‚ a blue-green solution. Afterwards‚ I added sodium hydroxide‚ and my solution colored to a dark blue solution called copper hydroxide. I heated the solution to evaporate the water and I got a brownish-blackish solid called copper oxide. Once the solid appeared‚ I poured

Reaction Essay: The Corporation The documentary The Corporation‚ directed by Jennifer Abbott and Mark Achbar and produced in 2004‚ although bias‚ opens many doors for discussion in regard to capitalism and the role of corporations in our lives. I found the documentary to be presented professionally‚ and filled with legitimate facts more so than extreme opinion. The documentary truly outlines the "all-pervasive" role the corporation has taken as the "world’s dominant institution". The film opens

Copper vs. Fiber Modern telecommunication networks rely primarily on two types of cable. Older copper cables have been replaced in many cases by fiber optic "light pipes‚" first in undersea cables and major intercity trunks‚ and later directly to many homes and businesses. Principles Copper cables carry information as an electrical signal‚ which may be digital‚ as in phone lines‚ or analogue‚ as in audio speaker cable. In optical fibers‚ however‚ data is carried digitally by light from a laser
