Copper conducts heat well because its atoms contain only one free valence electrons in the outer shell. Elements with a low number of valence electrons transfer heat the best, and copper has only one.Know More
Valence electrons move about freely. Just as the impact of a billiard ball striking another billiard ball is greater than when it collides with multiple balls, a single electron imparts significant energy to other electrons. Since copper has only one electron in its outer shell, it transfers a strong repelling energy to electrons with which it collides.
It is the degree of energy within the metal that imparts heat. Since heat increases when the subatomic particles are able to move without resistance throughout the metal, copper is a good conductor of heat. If heat is applied to one end of a cooper wire, it travels quickly to the other end, as the electrons move unimpeded by resistance.
Electrical conductivity is indirectly proportional to resistance a metal has when an electrical field is applied. Conduction is proportional to the current. Copper has a low resistivity measured in ohms. Its conductivity, measured by siemens per meter, is high. Copper is second only to silver in its conductive properties.Learn More
Of the elemental metals, silver is the best conductor of heat. It has a thermal conductivity of 235, meaning that it is able to transmit that amount of heat energy a single foot per hour per degree Fahrenheit.Full Answer >
Metals are good conductors of electricity because their atoms contain at least one free electron. They are also considered excellent heat conductors, because the metal ions in the lattice are closely packed together, and the delocalized electrons can bring kinetic energy through the lattice.Full Answer >
Copper's outer electrons are detached easily, making it great at causing an electron chain reaction. Copper is also used because of its price. While its price is increasing, its still far cheaper than other conductors.Full Answer >
Copper is a good conductor of electricity because the valence electrons are free and repel each other so strongly that it causes the repulsion of other electrons. This essentially forces the electricity down the piece of copper, or conducts it down the metal.Full Answer >
