electrodes are used in all types of electric furnaces.
The electrical conductivity
carbon and graphite are one in the same, graphite is a form of carbon a use for graphite is the lead in your pencil (it's not actually lead, it's graphite) and it is also a good lubricant ;)
No. Graphite is a solid, not a gas and is safe enough for everyday use in pencils.
Graphite is not rare as we know it. Graphite is an allotrope of the element carbon, and carbon is relatively abundant in the earth's crust. You can read more here: http://en.wikipedia.org/wiki/Graphite
Pencils use Graphite, not lead. Graphite is made of carbon, and no one mistakes a pencil of having carbon. They may mistake it of having lead, in which it is corrected that pencils no longer use lead-but instead use Graphite, which is made of carbon. It is not often mistaken that a pencil is made of carbon. Because it is made of carbon, so how you can make a mistake by thinking the pencil is made of graphite? Its true, not a mistake. This riddle is probably backwards? Or its just a trick question, I dont even know.
graphite is used as lubricant in machinery.also it is used in making leads of pencils.hence graphite is useful.
1) Graphite is used for making the cores of our pencils called pencil leads. 2) It is used for making carbon electrodes. 3) Powdered graphite is used as lubricant.

No, it is a pure form of the element carbon composed of sheets of covalently bonded atoms.

No, we don't use galena is pencils. Galena is the primary ore of the metal lead, and this mineral, PbS, is recovered for that purpose. We also often recover silver as a byproduct of lead processing. It is graphite that is used in pencils, and the mineral graphite is an allotrope of carbon.
The "lead" is a mixture of GRAPHITE and CLAY. It is squirted out like spaghetti and baked hard.
