Q:How much copper metal obtained?
About 1287.87 tons as nearly as I can figure. To 3 significant figures that weould be 1290 tons.
Q:why the copper has the red color ?
copper is pink naturally. those brown looking one could be copper1 oxide or some form of alloy.
Q:Can a copper figurine hurt my fish in a fresh water tank?
copper is toxic for all living things in high doses. a copper figurine in a fish tank will leak copper into the water.
Q:Is copper....?
yes durecel and others coat the top and bottom with copper so it will conduct better and more electricity.
Q:What are the advantages of a copper tube radiator over other radiators?
Tube convection radiator can be considered from the following 5 aspects: (1) tube convection radiator appearance and fine processing, high quality products of steel plate stamping molding shell cooling after surface spray treatment, high strength, beautiful appearance, can be removed from the customer decoration housing use wood shell radiator cover. (2) energy-saving product is light, small volume, convenient construction and installation for the domestic equivalent volume of copper pipe convection radiator heat loss minimum, for customers to save a lot of space, saves the construction area and improve the utilization rate of the room, saving the purchase cost, light weight, reduce the building load.
Q:Copper and Silver?
In fact silver is a better conductor of electricity than copper but copper wires are used at places where these are not directly exposed to the atmosphere as copper turns green forming copper carbonate and oxide etc, In case of overhead cables these cables remain exposed to the atmosphere hence in place of copper silver is preferred.
Q:Can i melt glass with heated copper?
Copper would have to be in liquid form (over 1083 C) to melt common glass, whose melting point is about 1500 degrees Celsius. Let alone other types of glass, which can reach an excess of 2300 degrees Celsius before melting. Pliers, tweezers, etc. would melt at about the same range, depending on the exact chemical composition.
Q:Can copper tubing be exposed to kerosene fire?
NO
Q:1810 Paul Revere Copper Pots and Pans?
Paul Revere Cookware
Q:Why are almost all copper pots lined with steel?
Copper is reactive with acidic foods, it will leach or shed into whatever you are cooking and leave a bad taste, stainless steel does not. Copper is used mostly just to line the bottom of the pan due to it's excellent heat conductivity.
