Copper is a good conductor of heat. This means that if you heat one end of a piece of copper, the other end will quickly reach the same temperature. Most metals are pretty good conductors; however, apart from silver, copper is the best.
It is used in many heating applications because it doesn't corrode and has a high melting point. The only other material that has similar resistance to corrosion is stainless steel. However, its thermal conductivity is 30 times worse than copper's.


Copper is made from a lattice of ions with free electron. The ions are vibrating and the electrons can move through the copper (rather like a gas).

Its mostly the same reasons as every other metal being good conductors, however copper is commonly used because of its relative abundance and high melting point. Google can probably sort you out.

I think that the mark schemes like the phrase 'sea of delocalised electrons'. Merlin98 is right in the fact that the delocalised electrons can move freely throughout the metal lattice and transfer energy to the metal ions.
