The best conductor of heat is diamond with a thermal conductivity of more than 2,000 watts per meter per degree Kelvin at room temperature. Silver is the material with the second-highest thermal conductivity at 429 watts per meter per degree Kelvin. This makes silver the metal with the highest condu


Water is a poor conductor of heat, and is actually classified as an insulator of heat. Materials that are good conductors of heat and of electricity must have free electrons that can carry the energy from one compound to the next.


Air is not a good conductor of heat, as it actually serves as an insulator when it is contained in an enclosed area. Air helps to prevent heat loss, instead of transferring heat to or between surfaces.


Uranium and Radon, the densest solid and gas respectively, are the best conductors of heat. The ability to conduct heat is called specific heat and is closely linked to density. The denser a material is, the closer its specific heat is to zero and the more easily it conducts heat.


Many metals, like silver, copper, gold and aluminum, are good thermal conductors. Thermal conductors are materials that heat passes through easily. Conduction, or the transfer of heat, can take place within a single material or between two objects.


Metals conduct heat well for two reasons: metal ions pack very closely together in their molecular lattice, and electrons drifting through the metal carry kinetic energy around the lattice. The result is a quick elevation in particle motion that is expressed through heat energy. This conductivity is


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.


A poor conductor of heat is any material that can not transfer heat. Poor conductors have a low density thus the particles in a given volume of the material are not enough to collide and transfer heat. Examples of poor heat conductors include air, wood, paper, cloth and water.


Examples of conductors include the human body, metals, aqueous solutions of salt, graphite, copper, silver and gold. Conductors are materials that can transfer heat and transmit electricity. Conductors have a high density, allowing particles to flow freely and collide.


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.
