What is the structural difference between diamond and coal?
Ajayosme
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 is the difference between jet and black onyx?
Jet is a form of coal (lignite); onyx is a variety of silicon dioxide.
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.
Is coal a metamorphic rock?
Coal when subject to mild metamorphism turns into Anthracite, in which the carbon content is between 92% and 98%. If squeezed and heated still further, the coal will transform into graphite and of cause if the taken to extremes diamond will be produced, but that would require the coal to be taken deep into the earth's mantle.
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 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.
Is coal a black diamond?
No. coal is coal and diamond is diamond. They are both formed from carbon, but diamond is much harder than coal.
What is the difference between thermal coal and steam coal?
These are same
What are the differences between coal and diamond?
Besides the cost? They are formed in different ways. While both are based on carbon, coal contains many other materials. The greatest difference is the pattern in which the carbon atoms are linked in the crystal structure.
Is diamond and coal minerals?
Yes. Both diamond and coal are formed from carbon.
What is the difference between obsidian and coal?
Obsidian has a higher luster(shinier) than coal, coal is organic, and coal is sedimentary and obsidian is igneous
What is the difference between peat and brown coal and black coal?
peat is soft and the others aren't
What phases does coal go through before it forms a diamond?
A diamond is not formed from coal. Diamond and coal are both allotropes of carbon, and are formed by different processes.
Why does a diamond turn into coal when it's burned?
Diamond does not turn into coal when exposed to flame.
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.
What type of coal turns into a diamond?
No 'coal' turns into 'diamond'. Both coal and diamond are composed of carbon, each being formed at different layers in the earth's mantle.
The difference between traditional and non-traditional source of energy?
difference between traditional sources of energy and coal
Will a diamond turn back into coal?
No,The process in which turns coal into diamond cannot be reversed or "undone"
