Um. I think its because its black and black conducts heat. DON'T TELL YOUR TEACHERS THIS IT'S JUST AN IDEA! Please if you do tell them that its an idea and if you'r old enough to go to uni or collage you should be answering this, not me.

Things that conduct electricity?
"things that conduct electricity" is a very common question, but however is different than "what things conduct electricity" things like water with salt dissolved into it, wood, metal, and SOME plastics conduct electricity, but copper and silver are the best even though people think gold is.
Who made the first pencil?
n ancient Rome, scribes wrote on papyrus (an early form of paper) with a thin metal rod called a stylus, which left a light but readable mark. Other early styluses were made of lead. Today we still call the core of a pencil the "lead" even though it is made from nontoxic graphite. The earliest graphite pencils had no outer surround of wood, the were just graphite rods, and were used even when I was a boy in school, we had slates that we wrote on, then prior to timber they were wrapped in paper so well you would have thought it was wood.
What are some materials that conduct?
Some materials that conduct include gold, wood, steel, water, and even copper. Most metals conduct well and are used to carry heat or electricity. Aluminum is another metal that conducts well.
Can the water from a faucet conduct electricity?
Yes all water can.... even dirty water.
Is it true that most pencils are filed with the element lead?
No. This is totally untrue. There is no lead in pencils - not even in the paint they are painted with! The reason for this is caused by confusion over the name of the filler. The substance inside a pencil that does the actual writing is called graphite. This is a crystalline form of carbon (another is diamond, another is a substance called buckminsterfullerene, and the third, non-crystalline form, is charcoal). The graphite is often mixed with differing amounts of clay to create pencils of different hardnesses. Graphite is found as a mineral in the ground. Lead is also found as a mineral in the ground as the lead ore 'lead sulphide' or 'Galena'. The mineral Galena looks very similar to graphite, except that graphite is darker in colour than lead ore. Therefore, many years ago graphite used to be called 'black lead' from its appearance. So, when pencils were invented, they were filled with graphite - or 'black lead', and eventually this was shortened to 'lead' but there is absolutely no connection with the 'lead' (i.e. black lead) found in pencils with the metal lead. The "lead" in pencils was always, is, and always will be, made of graphite.
Why graphite is used in battery?
Graphite is the only non-metal exception that can conduct electricity. Hence, even though graphite is a non-metal, it is used in batteries.
Is graphite a metalloid?
graphite is a form of carbon that forms in layers which is why it is able to be used in pencils, because the layers can slide off and get left on the page. Anyway carbon is a non-metal so graphite is a non-metal.
Which has the less density graphite or diamond?
Graphite is less dense than diamond, due to the differences in crystal structure.
Is bromine a metal?
Bromine is not a metal. It is a nonmetal halogen and is the inly nonmetal that is liquid at room temperature. Its chemical symbol is Br and has an atomic number of 35. It is reddish-brown in color with a metallic luster (even though it is not a metal).
Is graphite harmful to humans?
No. Graphite is not poisonous, not even in the form that is inserted into pencils. Graphite is occasionally ingested to absorb poisons before vomiting is induced. Still, it is not exactly recommended to chew on your pencil graphite 24/7. It won't kill you, though.
Does nitrogen conduct electricity?
Nitrogen is not considered to conduct electricity. This gas lacks the free electrons to support conduction.
How can you prove that there is salt in water even though you do not see the salt?
Taste it. Try to conduct electricity. Evaporate a sample.
Why is a diamond more valuable than graphite?
Both graphite and diamonds are both made up of carbon and their chemistry is one of the most important similarities that they have. Due to the fact that these minerals are highly solid and have a high melting point makes it very difficult to burn. Even though both of these minerals are chemically the same in composition, they are different in physical form and in other aspects. Even a non- expert can tell the difference between graphite and diamonds; graphite is more metallic and opaque and diamonds are transparent and brilliant.
What is a pencil lead made out of?
A pencil consists of a thin stick of pigment (usually graphite, but can also be coloured pigment or charcoal) and clay, usually encased in a thin wood cylinder, though paper and plastic sheaths are also used. (Lead) from a pencil is actually graphite which is 100% carbon Graphite and carbon black, all elementary Carbon (C)

Can you ask the police to graphite?
what does this even mean? re-word your question
What things conduct heat?
Technically, everything. Any amount of matter will conduct heat as a matter of molecular vibrations. However, heat conduction increases with density and delocalization of bonds (metals are the best conductors, followed by some forms of graphite, then probably some organic molecules, then other molecules, then salts, then lastly rocks and such).
