A good conductor of heat is metal as it has free electrons that can also carry Energy aswell as the partials themselves. This can be used for a radiator so the room can be heated. A bad conductor of heat is polystyrene. This can be used for plastic cups so the drink stay hot longer.
A metal saucepan is a good heat conductor when used to cook food. The saucepan's plastic handle is a bad conductor of heat, and insulates the cook's hand from being burned when lifting the saucepan off the stove.
Generally speaking, materials that are good conductors of heat are good conductors of electricity. But there is a notable exception. Diamond, an allotrope of carbon, conducts heat better than any metal, but it is an electrical insulator.
Copper, silver and aluminum are all good conductors of heat.
Most metals are good conductors of heat and electricity.
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).
Some nonmetallic materials are good conductors, graphite being an example. In this form, it is considered a semi-metal for that reason. Normally, however, nonmetals are not good electrical conductors.
Materials that are poor conductors of heat are Plastic and Wood "example."
All metals are good conductors of heat.
Good heat conductors are drinking glass.
Metals are usually good conductors of heat and electricity.
Many metals are good conductors. While technically a fridge is one, that's probably not the answer you're looking for. Anything conducts heat, even humans. Believe it or not but diamonds are some of the best conductors out there.
They aren't necessarily good conductors of both (like diamond, which is a good conductor of heat, but not electricity) Graphite is one that is both, but most of them are metals.
because it's a good heat conducter Electric conductors tend to be good heat conductors, but the above seems reasonable.
