Someone wrote "what material has the highest R-value".
This answer is not conducive to progress in their learning. The "r" in R-value stands for Resistance, that is, resistance to flow of heat.
Conductivity is the reciprocal, or inverse, of the Resistivity.
"Thermal Conductivity" is transfer of Heat. Since Heat is ultimately the jiggling around of small bits of Matter (fundamental particles like electrons, protons and neutrons), then atoms (assemblages of these 3 fundamental particles), then molecules (assemblages of similar or dissimilar atoms), or also the jiggling around of atoms within molecules) - then the material with the highest Resistivity would be the Absence of Matter, this is, Vacuum (not quite a material, strictly speaking, but "found" between the walls of a vacuum, or "Dewar", flask).
For the material with (possibly) the lowest Resistivity, or highest Conductivity, try the Wikipedia article on "Thermal Conductivity". If you're a girl, it may be your best friend.
What else can I help you with?
Does thorium conduct heat and electricity?
Yes, thorium is a good conductor of heat and electricity. It has high thermal and electrical conductivity, making it useful in various applications such as in high-temperature environments and in certain types of electronics.
Does cesium conduct electricity?
Yes, cesium is a good conductor of electricity due to its high thermal and electrical conductivity properties.
Does sodium have high or low electrical conductivity?
Sodium has high electrical conductivity because it readily donates an electron to form a positive ion, which allows it to carry an electrical charge. This makes sodium a good conductor of electricity.
What is TF wire?
TF wire stands for "Transformer wire," which is commonly used in electrical transformers. It is designed to have low electrical resistance and high thermal conductivity to efficiently transfer electricity throughout the transformer. TF wire is usually made of copper due to its excellent electrical and thermal properties.
What is brass conductivity?
Brass has a moderate electrical conductivity, approximately 28% of the International Annealed Copper Standard (IACS). This means that brass is not as conductive as pure copper but can still be used in electrical applications where high conductivity is not required.
What is conductivity material?
This a material with a high thermal or electrical conductivity.Examples: silver, copper, gold.
What is thermal and electrical conductiuity?
Thermal conductivity is the ability of a material to conduct heat, while electrical conductivity is the ability to conduct electricity. Materials with high thermal conductivity can transfer heat quickly, while those with high electrical conductivity allow electricity to flow easily. Both properties are important in various applications, such as in electronics and thermal management.
How Molybdenum is electrical conductor or electrical insulator?
Molybdenum is typically considered to be an electrical conductor due to its high thermal and electrical conductivity. Its conductivity properties make it a desirable material for applications where good electrical conductivity is required.
Ability of material to conduct heat or electritcity?
The ability of a material to conduct heat is known as thermal conductivity, while the ability to conduct electricity is known as electrical conductivity. Both properties depend on the material's atomic and molecular structure, with metals typically having high electrical conductivity and a range of materials having varying thermal conductivity.
Do elements that have high electric conductivity also have high thermal conductivity?
Not necessarily. While there is some correlation between electrical and thermal conductivity in metals, there are exceptions. For example, diamond is a good thermal insulator despite being a good electrical insulator. Additionally, materials like ceramics can have low electrical conductivity but high thermal conductivity.
is a measure of the ability of a substance to transfer energy like heat energy or electricity?
Thermal conductivity measures a material's ability to transfer heat energy, while electrical conductivity measures its ability to transfer electrical energy. Materials with high thermal conductivity are good conductors of heat, whereas those with high electrical conductivity are good conductors of electricity.
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.
What is a material ability to allow heat to flow called?
The property is called the material's "thermal conductivity".
Do nonmetals or metals have high thermal and electrical conductivity?
Metals generally have higher thermal and electrical conductivity compared to nonmetals. This is because metals have a "sea of electrons" that can move freely through the material, allowing for efficient transfer of heat and electricity. Nonmetals, on the other hand, typically have fewer available electrons for conduction.
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.
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 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.
