A heat conductor is a material that moves heat energy between two points, and does so without involving fluid motion (convection), and without significant point-to-point radiation.
Some examples of conductors of heat are....
what is a conductor
electricity, heating and cooking (i think)
Conductors pull heat away from the component you are protecting from heat created from current flow. Keeping it safe from over heating and damaging itself.
Because metals are good heat conductors !
When a circuit is overloaded, the wires gain a lot of heat over a short time. The heating can cause sparks and shorting and these can in turn set up fires if they come into contact with combustible materials.
There are many experiments you can perform in order to prove that gases are poor thermal conductors. You can try heating up an enclosed space from the top and feeling the bottom for example.
because plastic melts on heating and metal doesnot melt on heating.metals are good conductors of heat.
Generally, things that feel cold to touch (in a normal temperature room and no heating applied to them) are good conductors of heat (metals for example). Poor conductors tend to feel neither hot or cold under normal conditions (wood for example).
Metals are exallent conductors of electricity due to the free valence electrons, however some metals can be used for heating to e.g. kettle. Coils in the kettle are large resisters which heat up the water. it comes down to what you actually mean why are metals nat used for heating because some are.
Conductors have low resistance. Recall Ohm's law. The higher the conductor resistance, the greater the voltage drop along the conductor, and the less voltage that is available for the load. The conductor resistance is a resistance in series with the load. Also, higher conductor resistance results in more electrical power being converted into heat, warming up the conductors. This is calculated with the formula P=I2R. The greater the resistance, the greater the power wasted heating the conductors.

Generally ceramics are insulators. Some exceptions: silicon carbide, molybdenum disilicide, zirconium dioxide - these materials are largely used as heating elements.
They are Conductors, not much for insulation though. Differences between conductors and insulators? Conductors let energy such as electricity .
