what is the difference between conductive and nonconductive substance?

Question

on the thermal level.

Answer 1

Conductive are materials that conduct heat very good
Non condictive are materials that conduct heat very baddly
Iron is a good conductive
Wood is not

Answer 2

Assuming you are referrign to electrical conductivity, let's consider what the electric current is -- a flow of charges under the inlfuence of an electric field. All substances we know (here on Earth) consist of electric charges, such as electrons and atomic nucleai. However, depending on the structure of the material, these charges may or may not move when the field is applied. This has to do with both chemical elements involved (for example, in metals electrons are loosely bound to nuclei and can skip from an atom to a different atom), and the crystalline structure (for example, carbon can exist as graphite, which is conductive, and as diamond, which is not).

For a complete solution, one must use quantum mechanics, hence a simple answer beyond that isn't possible.

As for thermal conductivity, it is due to both heat transmission via the vibration of of the atoms/molecules, and to the gas of conductivity electrons, if such is presents. That's why metals typically transfer heat so well - because they have that extra component, the electrons that behave like gas on top of the crystalline lattice.

Answer 3

There's no such thing as a non thermally conductive material. Some things conduct heat faster than others. But if it is matter, it conducts heat. The difference is how fast they can transfer heat.

Thermal insulators conduct heat very slowly. (example: asbestos)

Thermal conductors conduct heat very quickly. (example: diamond)

Answer 4

conductive facilitates (gives little resistance to) the transference of thermal energy - when exposed to heat, warms quickly and radiates/conducts that heat - ex: metal

nonconductive does the opposite - ex: wood, rubber

Answer 5

conductive substances have more free electrons, so a force applied on it can get a higher intensity of current, and current passing through a condensator ( the substance here) heats it
the non-conductive one has few free electrons

Answer 6

Metals are good conductor of Heat and Electricity. It means current can flow through it.
Non conductive means current can't flow through it.

Answer 7

conductive material means it transfers heat through its own molucules non-conductive does not do this.
All metals are conductive.

Answer 8

conductive- transfer hear
non-conductive - doesnt..
