Answer. Coal is made up of Carbon, Hydrogen, Sulfur, Oxygen, Nitrogen. Diamond,coal, and pencil lead have a lot of things in common. … … Diamond and Graphite are different and very much the same, both are made of pure carbon, but, one is soft and the other is hard.
What do coal and diamonds have in common?
Coal and diamonds share a common foundation, or base – the element carbon – represented by C in the periodic table. Carbon-based life forms, most commonly originating from plants, are transformed into coal by pressure. Carbon used to make coal is far from its purest form.
Do diamonds really come from coal?
Over the years it has been said that diamonds formed from the metamorphism of coal. According to Geology.com, we now know this is untrue. “Coal has rarely played a role in the formation of diamonds. In fact, most diamonds that have been dated are much older than Earth’s first land plants – the source material of coal!
What are the similarities between diamond and graphite?
Both graphite and diamonds are made out of pure carbon. The chemical composition of the two is exactly the same. This makes graphite and diamonds allotropes of carbon along with amorphous, which is commonly called soot or carbon black.
What does the graphite in your pencil have in common with a diamond?
Graphite and diamond are two forms of the same chemical element, carbon. … In graphite, carbon atoms are arranged in planar sheets that can easily glide against each other. This structure makes the material very soft and it can be used in products such as pencil lead.
How long does it take to turn coal into a diamond?
between 1 billion and 3.3 billion years
Which is more valuable coal or diamond?
A one pound diamond is worth anywhere from $2-6M depending on its grade. A pound of coal is worth a few pennies. Paradoxically, though diamonds cost more than coal, coal is more valuable.
What Rocks are diamonds found in?
Magmas That Carry Diamonds. Diamonds are known to be carried to the earth’s surface in only three rare types of magmas: kimberlite, lamproite, and lamprophyre. Of the three types, kimberlites are by far the most important, with several hundred diamondiferous kimberlites known.
Can Superman make diamonds?
Superman has the abilities necessary to create heat and pressure to form diamonds. … But we’re not talking about natural diamonds, we’re talking about man-made diamonds — or Kryptonian-made diamonds. Thankfully, scientists have been able to make diamonds in laboratories for some time now.
How does peanut butter turn into a diamond?
In his quest to mimic conditions deep inside the Earth, Dan Frost of the Bayerisches Geoinstitut in Germany has discovered a way to turn peanut butter and carbon dioxide into diamonds. … The process essentially extracts the oxygen from CO2, leaving behind carbon that, under intense pressure, and form diamonds.
Why is diamond harder than graphite?
The atoms within a sheet are held together by strong covalent bonds – stronger, in fact, than in diamond because of the additional bonding caused by the delocalized electrons. So what holds the sheets together? In graphite you have the ultimate example of van der Waals dispersion forces.
Why is graphite softer than diamond?
This means that each carbon atom has a ‘spare’ electron (as carbon has four outer electrons) which is delocalised between layers of carbon atoms. These layers can slide over each other, so graphite is much softer than diamond.
Why does diamond not conduct electricity but is very strong?
The rigid network of carbon atoms, held together by strong covalent bonds, makes diamond very hard. … Like silica, diamond has a very high melting point and it does not conduct electricity.
Can you really make diamonds from pencil lead?
Yet, their properties could not be any more different. In graphite, carbon atoms are arranged in planar sheets that can easily glide against each other. This structure makes the material very soft and it can be used in products such as pencil lead. … One way to turn graphite into diamond is by applying pressure.
Does microwaving pencil lead make diamonds?
In general, pencil graphite is not reactive enough to microwaves.
Can we convert graphite into diamond?
It is known that graphite can be converted into diamond when subjected to high pressure and high temperatures. The graphite-diamond transformation can be achieved directly by subjecting graphite to ultra high pressures (> 100 kbar) and temperatures ( > 2000°C).
