Coal transforms into graphite through a process called carbonization, which occurs over millions of years under high pressure and temperature conditions. During this process, the organic compounds in coal decompose and lose volatile substances, leading to an increase in carbon content. As heat and pressure continue to act on the coal, its structure becomes more ordered, ultimately forming the crystalline structure of graphite. This transition typically occurs deep within the Earth's crust, where geological processes facilitate the necessary conditions for this transformation.
What else can I help you with?
What is the most stable form of allotropic form of carbon?
Coal, graphite and diamonds are all allotropes of carbon and are stable at room temperature.
Does coal change into graphite?
Yes, coal can change into graphite through a process called metamorphism, which occurs under conditions of high pressure and temperature over geological time. During this process, the carbon content of coal becomes more ordered, transforming it into graphite, which is a more stable form of carbon. However, this transformation typically requires millions of years and specific geological conditions.
How is a graphite different from other allotropes of carbon?
Diamonds, coke, coal, graphite, fullerenes
What makes diamonds and graphite two forms of the element carbon so different?
Well to be very upfront diamond is very heated and compressed carbon (coal graphite) while graphite is more "pure" carbon than diamonds
What element is present in lead graphite?
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.
What the different between graphite and coal?
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.
What is the most stable form of allotropic form of carbon?
Coal, graphite and diamonds are all allotropes of carbon and are stable at room temperature.
Does pencil lead have coal in it?
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.
A type of coal commonly used in pencil lead?
Graphite is used to make pencil lead, but it is not a form of coal.
What metamorphic rock does anthracite coal turn in to?
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.
What are graphite's uses?
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.
Does coal change into graphite?
Yes, coal can change into graphite through a process called metamorphism, which occurs under conditions of high pressure and temperature over geological time. During this process, the carbon content of coal becomes more ordered, transforming it into graphite, which is a more stable form of carbon. However, this transformation typically requires millions of years and specific geological conditions.
What does diamond coal graphite cokeand buckminsterfullerene have in common?
Diamond, coal, graphite, coke and buckminsterfullerene are composed primarily of carbon and are insoluble in water.
Is one form of carbon a diamond?
Yes. Other allotropes include coal and graphite, such as you might find in a pencil as 'lead'.
What material found in nature can turn to diamond?
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
How is a graphite different from other allotropes of carbon?
Diamonds, coke, coal, graphite, fullerenes
What are two examples of carbon?
coal and graphite
