The difference between graphite and diamond is in the three-dimensional
arrangement of the carbon atoms in the material. Graphite is made of flat
sheets of carbon atoms in a hexagonal arrangement. The sheets stack one
over the other, with only weak interactions between sheets. Diamond is not
arranged in sheets; instead, each carbon atom is connected to four others in
a tetrahedral arrangement. It turns out that this arrangement is not as
different from the structure of graphite as it sounds. If the sheets of
graphite are compressed close enough together, the carbon atoms will be in
just about the right position to make the bonds of diamond. In fact, at
high temperatures and pressures, this indeed happens.

What else can I help you with?
What kind of rock is diamond?
It's not a rock, it's a pure carbon mineral formed at super high pressures and temperatures - In kimberlite eruptions or in artificial explosion.
What is the difference between a natural landform and a natural resource?
A natural landform is the valleys and hills that nature has created. A natural resource is the coal, oil and iron ores, and so on.
What is Pennsylvania's most valuable mineral?
Coal is the most valuable mineral in Pennsylvania. The state has abundant coal reserves, making it a significant contributor to the state's economy and energy production.
What does this solid carbon become part of?
Solid carbon (C) may be diamond, graphite, coal, carbon black etc.
What is the specific gravity of sapphire?
"If you have ever watched one of the older Superman films, you may have seem the famous clip where Superman turns a chunk of coal into a diamond. This is impossible. The density of coal is 1,330kg/m^3 whereas for diamond it is 3,520,000,000 kg/m^3. When diamond is divided by coal, we learn that diamond is 2,646,616.5414 times more dense than coal. If Superman really was to turn coal into that perfect diamond he would need 9316kg of coal, that is about four or five SUVs. That would be cool." .... Ah.. no. The density of diamond is typically around 3,500 kg/m3, and thus has a relative density of 3.5 i.e. a density 3.5 times that of water. If the density was 3,520,000,000 (!) as stated above, a ladies wedding ring, with a volume of 1cm^3 (big rock!) would weigh (i.e. have a mass of) 3,520 kg!! That's over 3 tonnes. Not even a Bavarian Barmaid could handle such a ring! Superman could achieve his feet, though his diamond would be one third the volume of the coal he started with.
How do coal and diamond differ?
Coal and diamond are both made of carbon, but they have different structures that give them distinct properties. Coal is formed from decaying plant matter under pressure, while diamond is formed under extreme heat and pressure in the Earth's mantle. This difference in formation makes coal soft and brittle, while diamond is the hardest known natural material.
Can coal change into a diamond?
Yes, coal can change into a diamond through a process called metamorphism, which involves high pressure and high temperature deep within the Earth's crust. Both coal and diamond are made of carbon atoms, but the arrangement of the atoms is different, resulting in the difference in their physical properties.
What is the only difference between coal and a diamond?
I think the only difference is the exposure to pressure and time ... (which is thousand years) Also, diamond is much more dense and burns more cleanly into CO2 because it is pure carbon, unlike coal, which also has hydrogen in it. +++ The first sentence above is wrong on time. Most of the world's coal reserves formed more than 300 million years ago, over some millions of years, in the Carboniferous Period. Not "thousand". There is another, very big difference. Coal is a sedimentary rock, and hydrogen would not make it burn less cleanly - even if it could exist within coal as hydrogen alone. Most of the impurities in coal are sulphur and organic compounds. Diamond occurs within certain igneous rocks formed at great depth hence great pressure and temperature.
What is the link between coal and diamond?
Coal has never been at sufficient depth and temperature to be turned into diamond. Coal is simply fossilized plant remains that are high in the element carbon, of which the mineral diamond is also composed.
Is diamond and coal minerals?
Yes. Both diamond and coal are formed from carbon.
Why is coal referred to as black diamond?
Probably because both coal and diamond are composed of carbon.
Will a diamond turn back into coal?
No,The process in which turns coal into diamond cannot be reversed or "undone"
What is the difference between coal mined in the appalachians and in the western states?
coal in the western areas has a lower energy content
What is the difference between coal mined in the Appalachian and in the western states?
coal in the western areas has a lower energy content
What is the difference between coal mined in the Appalachians and in western states?
coal in the western areas has a lower energy content
Coal and diamond are two different forms of carbon which is more dense?
Diamond is more dense than coal. This is because diamond has a more tightly packed crystal structure, making it denser compared to coal which is less compact.
Is coal stronger than diamond?
No, coal is not stronger than diamond. Diamond is one of the hardest known natural materials, while coal is much softer and less durable.
