Q:What are some of the negatives sides of copper?
Copper does not insulate temperature or magnetic fields. Copper exposed to minerals in water can cause corrosion and weaken the metal. Some people are allergic to copper. Copper can oxidize causing it to develop a green film.
Q:how copper is processed?
Copper ore can be of many types and the simplest one to extract copper from is the one containing copper sulphide.Such an ore is piled in great heaps in a depression in the ground(think a swimming bath)and kept wet but not submerged.In the course of a week or so the oxygen in the air oxidises the copper sulphide copper sulphate which is a blue salt which dissolves in the water.The next thing is that iron scrap is added to the blue solution and the copper is released onto the surface of the scrap.(reaction CuSO4 + Fe ----->FeSO4(in solution in the water) + free copper.When enough copper if formed the copper covered scrap is heated in a furnace in a reducing atmosphere so that the copper melts and is collected as ingots and the remaining iron returned to the copper swimming pool. To get pure copper(99.99% pure or better) the ingots from the process above are rolled into flat sheets which are made the anode in an electrolytic cell(dilute sulphuric acid again)and with a starter cathode os pure copper.Im not going into the chemistry here but an electric current is passed through the solution and copper dissolves from the impure copper and is re-deposited onto the pure copper starter sheet.
Q:Why use copper tube for air conditioning?
The iron pipe is easy to corrode, and the specific heat of the copper is larger than that of the iron, and the heat absorption and the heat dissipation effect are good,
Q:What copper is the copper tube used for air conditioning?
2. the quality of the same volume is about 15% heavier than that of ordinary steel. Because of its rose red, the surface of the formation of oxide film after purple, it is generally known as red copper. It is a copper containing certain oxygen, which is also called copper containing oxygen.
Q:Is copper a good metal to make coins with?
Q:BackGround History of Copper?
Q:Mass after Burning copper?
In all liklihood you did NOT burn the copper, you only burned the surface of the copper. In this case, the copper itself probably weighed a good deal more than the amount converted to oxide, so the mass change was unnoticeable. To really see the difference, you would need temps in excess of 3000 degrees and an oxygen-rich environment or some other method for fully oxidizing the copper. same is true for the steel wool except that steel will tend to flake away as it oxidizes (rather than forming a protective coat). Fully convert the steel wool and you will similarly see the mass change as oxygen is absorbed.
Q:Is it OK to use a copper pipe as a shaft to mount a lamb to barbecue on a spit?
Copper pipe is an alloy - not pure copper. I would not recommend it. Copper is also too soft - it may bend in the heat of the barbecue, especially if weighted down with a heavy piece of meat.
Q:Does the human body produce Copper?
Yeah you can only make copper through nuclear fusion or fission, none of which happen in our body. Must be taken in through our diet. It's only a trace mineral, we need it in small quantities.
Q:Is the diameter of the air conditioner copper pipe inner diameter or outer diameter?
The diameter of the air conditioning copper pipe is determined according to the outside diameter, mostly in english. 19 is also English 6.
