Carbon, in the following allotropic states, has the highest thermal conductivity:
- Graphene, a planar material, conducts at 5300 W/(m·K).
- Carbon Nanotubes, an axial material, conducts at 3000-3500 W/(m·K).
- Synthetic Diamond, an isotropic material, conducts at 2320 W/(m·K)
- Annealed Pyrolytic Graphite, a planar material, conducts at 1700 W/(m·K).
- Natural diamond (isotropic) conducts at approximately 900 W/(m·K).
- These are followed by all other materials including the excellent metals: silver, copper and aluminum.
Note: Most materials you may encounter are isotropic(same in all directions) conductors. There are few planar(in a plane) and axial (in a line) conductors; mostly crystals.

∙ 13y agoAllotropes of Carbon are high in thermal conductivity - followed by metals like silver, copper and aluminum, in that order.
I suppose it would help put this in perspective by pointing out that engineered conducting structures such as heat pipes, and convection of fluids (liquid, gas, plasma and suspended solid particles) can transport heat much better than any solid.

Graphite (the last form of carbon) has a range of conductivity, depending on compression, from poor to excellent.

What Is a material that allows heat to flow through it easily?
Thermal conductors let heat move through them. Metals are part of this group.
Does the value of thermal conductivity depend on the dimension of the specimen?
Thermal conductivity is an intensive property. It is inherent in the material but not dependent on the amount of material. This should not be confused with the rate of heat conduction which can depend on the dimensions of a material. There is one case where the thermal conductivity might depend on the dimension of the material - when the conductivity is not uniform with direction, i.e. where conductivity laterally is different from conductivity longitudinally. When the orientation of the material changes the conductivity, the dimensions can have an effect on the apparent bulk thermal conductivity.
Which type of heat transfer occurs across a temperature gradient within a solid?

What do you call a material that conducts heat well?
A material with a good thermal conductivity or a thermal conductor.
Which is the best thermal and electric conductive material?
The best electrical-conducting materials are various superconductors, which display zero resistivity, or in other words perfect conductivity. Since about 1993, the highest-temperature superconductor known has been a ceramic material consisting of thallium, mercury, copper, barium, calcium and oxygen (HgBa2Ca2Cu3O8+δ) which is superconducting below 138 K. Several allotropes of carbon seem to share the palm for the highest electrical conductivity at room temperature. Graphene is one. Carbon nanotubes in the direction along the tube another. The known material with the highest thermal conductivity is a supercooled form of liquid helium: helium II The known material with the highest thermal conductivity at room temperature is graphene.
What material warms the fastest in thermal conductivity?
Graphene
What does thermal conductors mean?
A thermal conductor allows heat to readily flow through itself. An example of a material with a low thermal conductivity would be air, and an example of a material with a high thermal conductivity would be steel.
Why conductivity of diamond is highest being a nonmetal?
It would help if you specify whether you are talking about thermal conductivity, or electrical conductivity. Diamond certainly doesn't has the highest electrical conductivity. Its thermal conductivity is one of the highest known, and - if a synthetic diamond is made from pure (99.9%) C-12, it is indeed the highest. The Wikipedia article attributes this to a strong covalent bonding.
What metal has the highest electrical and thermal conductivity of all?
Silver
Define thermal conductivity?
ability of the material to resist the temperature
A what is a material through which energy can be easily transferred as heat?
Any material which has high thermal conductivity can easily transfer energy as heat. As far as I know, all metals have high thermal conductivity. Copper, gold and silver especially have high thermal conductivity. Diamond and graphene have VERY high thermal conductivity, so this is not restricted to only metals.
