Why does iron conduct heat?

Why do metals conduct heat so well? Theelectrons in metal are delocalised electrons and are free movingelectrons so when they gain energy (heat) they vibrate morequickly and can move around, this means that they can pass on theenergy more quickly.

Also, is Iron good conductor of heat?

Because the electrons involved in the metallic bond ofiron are free-moving, iron is a goodconductor. When in their liquid or gas states, the electrons ofIn order to conduct electricity, a substance needs to have chargesthat are free-moving. Metals, such as iron, have metallicbonds.

Secondly, what metals conduct heat the best? As you can see, out of the more common metals,copper and aluminum have the highest thermal conductivity whilesteel and bronze have the lowest. Heat conductivity is avery important property when deciding which metal to use fora specific application.

Consequently, why does sodium conduct heat?

In a molten state the bonds become much weaker due tothe increasedkinetic energy of the atoms, the electrons canmove more freely, and the compound can conduct electricity.-sodium metal demonstrates metallic bonding when itis in solid state. This sea of electrons are free tomove around.

Which material has highest thermal conductivity?

Along with its carbon cousins graphite and graphene,diamond is the best thermal conductor around roomtemperature, having thermal conductivity of more than 2,000watts per meter per Kelvin, which is five times higher than thebest metals such as copper.
