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 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 4

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 5

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 6

They both conduct a chemical change toward an object

Answer 7

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

Answer 8

Convection requires the flow of some fluid.

Answer 9

Both can contact a chemical change toward the substance
