For our science assessment we had the task to research about a metal of our choice. Since I am really into computers, I chose copper. A metal used in all kinds of wires, cpu’s and other stuff without a computer wouldn’t work. This fits really well into what we have to do for the second part, describe how this metal has helped human society.
Copper is one the most used natural resources. Copper is used for many things. It is considered a natural resource because the Earth makes it. Copper is formed when molten rock has copper
Copper is one of the earliest elements known to man. Because of its distinct red color, Copper is very easily identified. In the ancient times, copper could be found lying in the ground in its unattached state without interaction to other substances. Copper and its compounds have many uses in today’s society.
Copper has made an impact on life for over 10,000 years. It was the first metal that was known to man for a while, but it has many uses that people are able to benefit from. Back then copper was mostly used for decorative items just like gold and silver is used for jewelry now (Copper Development Association Inc. 2015). It was also used for statues because copper is able to bend easy. Now copper is used for coins, medical use to study metabolism and gastrointestinal diseases, good conductor of heat and energy, and it is used for plumbing pipes (Winter).
The experiment was performed to show the many chemical reactions and states of copper, a very common yet important element that can is found in many useful compounds throughout the world. Copper was combined with many different compounds and elements to cause chemical changes in the state of copper. These reactions were conducted to display the several different states of copper throughout the cycle, ultimately restoring the copper after the metal seemingly disappeared.
The first metal ever discovered Gold. Gold, was mainly used by the Stone Age men as jewelry. Gold was a very popular metal due to its scarcity, value and mankind's interest with the metal. The next metal discovered at 4200 BC is Copper. The use of Copper and its antiquity was more significant than gold, due to the first tools and weapons being used was Copper.
During lab, we put the metal copper under different circumstances so that we could gain a better understanding as to what goes on in the copper cycle. Throughout each stage of the copper cycle, we deduced what type of chemical reaction took place based on observation, made observations about the state of the metal and what type of environment it was subjected to, and determined what the net ionic equation was for each stage. Following the experiment, we calculated what the percent yield was and compared the changes in mass from the initial stage to the final stage.
To choose the use of copper over aluminum, you need to consider conditions such as electrical conductivity. Copper conducts electricity better than aluminum because of its high capacity over volume. Another factor to consider when choosing one element over the other is expansivity. When materials are used to make contacts expand, their clamping force increases hence deforming points of contact while creeping them. This condition makes aluminum less suitable for making electrical contacts than copper. The reactivity of copper is higher than that of aluminum hence making it less suitable to make cooking pots and pans. Aluminum is best suited because it forms a thin film of aluminum oxide that does not
Copper is a metal that has been used by humans essentially since the beginning of existence as it is said to be only the second metal used by man after gold. Therefore, copper production has been an important part of life for thousands or years and still is today. The copper cycle is an important because it provides a basis for how copper can be recovered from various compounds that it exists in during its so-called “life-cycle” . The life cycle of copper conserves this now scarce metal by allowing the recovery of the pure substance at any point through experimental means. While copper is much more, scare in earths natural environment today it is still an incredibly important product. Copper is used in manufacturing wiring for electricity as
One positive impact of copper mining is that it has a great impact on the economy, as it is a multi-purpose metal. It can be used for infrastructure, motor vehicle radiators and heating systems as well as electrical generators and motors for electrical wiring. Furthermore, various establishments will purchase the metal. Although it’s not as costly as gold, copper is sought out for its versatility.
Many homeowners decide on copper plumbing because it is the most traditional choice. They are familiar with the material, so they know exactly what they can expect once it is installed in their home. Copper has been a proven material for home plumbing, lasting between 50 and 70 years. You won’t even have to think about
