Why is graphite a poor conductor of electricity at high temperatures?

Carbon is a poor conductor of electricity because it is a nonmetal, which in general are poor conductors of electricity.
However it should be noted that, graphite, an allotrope of carbon is a very good conductor of electricity.

Why is iron a conductor of electricity?
iron is a high density metal, thus a very good conductor of electricity
What non metal objects conduct electricity?
Only eighteen elements in the periodic table are generally considered nonmetals, compared to over eighty metals. Although nonmetals are generally poor conductors of heat and electricity when compared to metals, many of them still can conduct electricity. The metalloid elements (such as Silicon and Germanium) can conduct electricity and are used as semiconductors in electronics. Many generally nonmetal compounds (composed of nonmetals) can also conduct electricity, with gallium arsenide, and silicon carbide being popular components in semiconductors as well.
Explain how air can become a good conductor and what happens when this occurs?
air can become a good conductor when it is heated to very high temperatures
Why does a battery get hot when aluminum foil is touching both sides?
Batteries give of electricity, aluminum conducts electricity, electricity can have high temperatures.
Is glass a bad conductor of electricity?
Yes it is. It's used as an insulator in high-power installations.
What makes graphite?
Graphite is an excellent conductor of electricity and heat. Graphite can withstand extremely high temperatures and is not affected by majority of reagents and acids. This property gives graphite uses which are unique and peculiar.
Is graphite a conductor or insulator?
Graphite is a conductor of electricity, but its conductivity varies greatly with direction: Conduction is high along the plane of the sheets of carbon atoms found in a single crystal of graphite, but much lower perpendicular to this plane.
What property makes graphite an unusual non metal?
Graphite is an excellent conductor of electricity and heat. Graphite can withstand extremely high temperatures and is not affected by majority of reagents and acids. This property gives graphite uses which are unique and peculiar.
Is graphite a high resistance or low resistance of electricity?
Graphite is low resistance of electricity...
Is glass a poor conductor?
It depends on whether you mean heat conductor or electrical conductor; in either case it is a poor conductor at room temperature; but at very high temperature it is a good electrical conductor but still a poor heat conductor
Is boron a good conductor of electricity?
Boron is not a good conductor of electricity at room temperature, but is a good conductor at a high temperature.
Why is iron a conductor of electricity?
iron is a high density metal, thus a very good conductor of electricity
Why are electric wires usually made of copper?
Copper is a good conductor of electricity and it is cheap as well. Gold conducts electricity very well but comes at a high cost Graphite is very cheap but does not conduct electricity as well as copper
Which element at room temperature is a poor conductor of electricity and has a relatively high electronegativity?
Sulfur has relatively high electronegativity and is also a poor conductor of electricity at room temperature. Fluorine has the highest electronegativity and copper is a good conductor of electricity.

Does a glass get hot when you put hot water in it?
Glass conducts electricity well letting the heat flow through it. 2. OOPS! (it is only at very high temperatures that glass conducts electricity, and even then it is not a good conductor.) And glass is not a very good conductor of heat, but it will conduct heat albeit slowly.
Is Magnesium oxide a good conductor of electric?
Only when melted or dissolved in a polar solvent.
