Coal, graphite and diamonds are all allotropes of carbon and are stable at room temperature.
Diamonds, coke, coal, graphite, fullerenes
Well to be very upfront diamond is very heated and compressed carbon (coal graphite) while graphite is more "pure" carbon than diamonds
Graphite is a form of Carbon, so its carbon in lead graphite. Notice that lead itself is a different element but the term "lead graphite" is generally used for that black substance which makes the "lead pencils". Note that there is no lead in lead pencils, its carbon, in the shape of graphite.
Natural graphite is available from earth crust in the form of ore. It is beneficiated and made usable. It is available in crystalline, flaky and amorphous form. Synthetic graphite is made by man. Calcined petroleum mixed with coal tar and extruded at very high pressure. It is then treated in high temperature to a tune of above 3000 degree centigrade and carbon become graphitised.
Graphite and coal are both forms of carbon, but graphite is a crystalline form while coal is a sedimentary rock made up of plant material. Graphite is used for its lubricating properties and in pencil lead, while coal is primarily used for generating heat and electricity. Additionally, graphite is a good conductor of electricity and heat, whereas coal is not.
Coal, graphite and diamonds are all allotropes of carbon and are stable at room temperature.
No, modern pencil "lead" is actually made of a mixture of graphite and clay, not coal. Graphite is a form of carbon that is a good conductor of electricity and is commonly used in pencils due to its smooth writing properties.
Graphite is used to make pencil lead, but it is not a form of coal.
Anthracite coal, a type of coal with a high carbon content and low impurities, can turn into metamorphic rock called graphite under high heat and pressure. Graphite is a soft, crystalline form of carbon that is a good conductor of electricity.
Graphite is a pure form of coal or carbon. It is a good conductor of heat and electrcity. It is used as a neutron moderator in nuclear reactors of type Gas Cooled reactors.
Diamond, coal, graphite, coke and buckminsterfullerene are composed primarily of carbon and are insoluble in water.
Yes. Other allotropes include coal and graphite, such as you might find in a pencil as 'lead'.

That would be coal. --------------------------------- The correct answer is Carbon - Coal is also a form of carbon as is Graphite. There are 3 grades of Coal - Lignite, which is 55% Carbon - Bituminous, which is 75 to 90 percent Carbon and Anthracite,which is 90% Carbon and 10% impurites.(such as Sulfur) In summary- Diamond, Coal and Graphite are all Different forms of Carbon
coal and graphite
coal, in theory, should turn into diamonds if under intense pressure and heat for millions of years.
