The best element at conducting heat is silver, followed by copper, gold, and aluminum.
Nevertheless, diamonds are two to five times as good at conducting heat as copper, and graphene is twice as good as diamonds. (No, I am not making this up; please see the link below.)
Basically,thermal conductors are......Metals such as iron ETC. Polystyrene is a thermal conductor as well.Thanks
P.S There are loads more but i can't be bothered to answer them!SORRY! :)
Metals Generally, any subject with a melting point will conduct heat to some extent. Ferrous metals and cuperous metals are some of the best conductors of heat. Also, any material that will conduct electricity will usually conduct heat, as infared energy is part of the EM spectrum.
Conductors - Substances which allow electricity to pass through them easily are called conductors. These are made from materials which have low resistances. Metals like copper, aluminium, silver, iron, brass and also salt solutions are good conductors !
Metals are usually the best, but some metals are better than others. Silver and copper are at the top, aluminum and iron a bit lower.
a thermal conductor is any material that conducts heat, the best thermal conductors are solid metals. technicly all materials are thermal conductors.

What ARE material properties? Otherwise known as characteristics, these are the things that make a material useful. Mechanical properties: Ductility (elastic or plastic) Brittleness (stiffness), compression, tension, torque, shear, toughness, & hardness. Electrical properties: conductor, insulator, semiconductor Thermal properties: conductor or insulator Optical properties: transparent, translucent, reflective, opaque.
Actually tungsten is a great conductor of heat and electricity. Tungsten is used a light bulb filaments. If Tungsten was a poor conductor of heat and electricity the bulb in the circuit would not glow because there wouldn't be electricity passing through the circuit. Tungsten is also used as an electrode in gas tungsten arc welding. Electricity passes through the tungsten (negative) and moves to the workpiece (positive) for most applications.
Copper, aluminum and gold.
because of the free sea moving electrons
it is a very good conductor for electronics but, pathetically enough, we like it because it is shiny and rare
There are a number of materials that make good thermal insulators. Blankets and pockets of air make good thermal insulators for example.

Thermal conduction is caused by two different things: Phonon conduction and Electron conduction. Electrons are thermal conductors because electrons have mass and velocity, ie. they have momentum. Thermal energy can be carried by these electrons. What makes a good thermal conductor through the energy carrying of electrons is good electrical conductor. This is because if the electrons are bouncing all around the inside of the conductor, they are transfering their energy to the molecules/atoms of the conductor and not to the other "side". More technically, the crystal lattice of the conductor must be free of as many defects as possible, and the lattice atoms must have electrons in the the conduction band. The other thermal conductor is phonons. Phonons are basically a name we give to the movement of the lattice itself. Think of phonons as waves in a pool. The better the phonon conductivity, the better the thermal conduction. Think of phonons as a rope that is held at noth ends and you whip a wave across it. If there is a lot of tention, the wave will quickly travel to the other side. If it is loose, the wave will travel slowly and maybe not even make it to the other side. The technical equivalent is high bond strengths in the lattice. High bond strength between the atoms means that the phonons will travel faster because the movement of one atom will greatly affect the movement of the neighboring atoms. This is why diamond is such a good thermal conductor, it has very very strong bonds.
Salt must be mixed with water to make salt a good conductor.
Use a good conductor - if possible a super conductor.
Anything that isn't a conductor. Insulators don't conduct charges very well because their electrons cannot move freely.
Use a good conductor - if possible a super conductor.
