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.
What else can I help you with?
What material has the highest thermal resistance?
Diamond has the highest thermal conductivity among natural materials because of its rigid structure and strong covalent bonds, transferring heat efficiently.
How can one determine the thermal conductivity of a material?
The thermal conductivity of a material can be determined by conducting a thermal conductivity test, which involves measuring the rate at which heat flows through the material. This test typically involves applying a heat source to one side of the material and measuring the temperature difference across the material to calculate its thermal conductivity.
A material in which thermal energy is transferred slowly is a?
Material with low thermal conductivity.
What happens to thermal conductivity of a wall if its thickness double?
If the thickness of a wall is doubled, the thermal conductivity remains the same unless the material composition or other properties of the wall are altered. Thermal conductivity is a material property that is independent of the dimensions of the material. So, as long as the material itself doesn't change, doubling the thickness will not alter the thermal conductivity.
What does a higher thermal conductivity indicate about a material's ability to transfer heat?
A higher thermal conductivity indicates that a material is better at transferring heat.

What is a material ability to allow heat to flow called?
The property is called the material's "thermal conductivity".
Define thermal conductivity?
Thermal conductivity is a material property that describes the ability of a material to conduct heat. It is defined as the rate at which heat is transferred through a material per unit of thickness, area, and temperature difference. Materials with high thermal conductivity transfer heat more efficiently than materials with low thermal conductivity.
What do you mean thermal conductivity?
Thermal conductivity is a material property that describes how well a substance can conduct heat. It measures the ability of a material to transfer thermal energy through it. Materials with high thermal conductivity, like metals, transfer heat well, while those with low thermal conductivity, like plastics, do not.
What do you call a material that conducts heat well?
A material with a good thermal conductivity or a thermal conductor.
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 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.
