Copper has been used in cookware because of its good thermal conductivity. In Eastern and Western cooking traditions‚ copper cookware sets were popular because they provided the best conductivity‚ and therefore the most even heating and cooking. Copper pots and pans were a staple of the colonial kitchen and have withstood the test of time to remain popular in the professional and home kitchen alike. Copper cookware sets will typically include a saut� pan‚ frying pan and a sauce pan. These are essential

report 2. File the report 3. Communicate the results INTRODUCTION Traffic volume studies are conducted to determine the number‚ movements‚ and classifications of roadway vehicles at a given location. These data can help identify critical flow time periods‚ determine the influence of large vehicles or pedestrians on vehicular traffic flow‚ or document traffic volume trends. The length of the sampling period depends on the type of count being taken and the intended use of the data recorded.

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

the AL exam‚ make-up classes and tests were full of my schedule. I have to say that it was so tired. The pressure was just pushing me away from the books and notes; I didn’t want to face it. I still used all my effort and time to prepare for the tests at school; finally‚ there was no extra time for me to seriously follow my AL study plan. The mock exam was prepared in a very short time. I tried to cover all the materials shortly before the mock. The result is worst. However‚ after going through all

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

Copper and Molybdenum Deposits in the United States Copper and molybdenum resources were not recognized as valuable commodities until economic needs demanded the collection and processing of these minerals in large amounts. The most expansive deposits of copper and molybdenum occur in massive low grade ores and are found in intrusive porphyry formations‚ although many smaller sized but higher grade ores are located in non-porphyry areas. The nation has abundant domestic copper ore reserves but
