How does thermal conductivity differ from electric conductivity?

Answer 1

On deals with heat transmission (diamond is great at that) the other transmission of electrons (diamond is very poor at that)'

Most metals are fairly good at both.

Answer 2

Thermal energy exists in materials raised to a high temperature, because they can then transfer this energy to materials at lower temperatures. For example , heating radiators transfer energy to the building they are in. Electric energy is basically the movement of free electrons in a conductor, which can then do work such as turn an electric motor, or indeed produce thermal energy in a heating element,

Answer 3

Thermal conductivity refers to the ability of a material to conduct heat, while electrical conductivity refers to the ability to conduct electricity. Materials that are good thermal conductors may not necessarily be good electrical conductors, and vice versa. Thermal conductivity is generally influenced by a material's structure and vibration of its particles, while electrical conductivity is influenced by the presence of free-moving electrons.

Answer 4

Thermal conductivity refers to the ability of substance allowing heat to move from a region of high temperature to a region of low temperature. On the contrary, electrical conductivity refers to the ability of allowing an electric current to flow.

=====================

Thermal conductivity is generally related to the ability of atoms or molecules to transfer energy via collisions from an area of higher temperature (with faster, more energetic atoms/molecules) to an area of lower termperature (with slower, less energetic atoms/molecules). Electrical conductivity is related to the ability of atoms or molecules to transfer energy via the movement of electrons from one atom/molecule to the next.

Answer 5

the difference between thermal conductance and thermal conductivity is that:

thermal conductivity(k) and its unit is (W/m.K)it is coefficient of heat transfer through materials in contact with air (the out side layers).

thermal conductance(C) its unit is (W/m2.K)it is coefficient of heat transfer through materials at the middle or surrounding by anther materials(the middle layers).

Answer 6

Electrical Conductivity:

THE Electrical Conductivity OF A MATERIAL IS A MEASURE OF HOW READILY ELECTRICITY PASS THROUGH IT.

Thermal Conductivity:

THE Thermal Conductivity OR HEAT CONDUCTIVITY OF A MATERIAL IS A MEASURE OF HOW READILY HEAT PASS THROUGH IT.

Answer 7

They both conduct a chemical change toward an object

Answer 8

Both electrical and thermal are reduced by the same factor..

Answer 9

Convection requires the flow of some fluid.

Answer 10

Both can contact a chemical change toward the substance
