Both diamonds and coal are compressed of carbon but are they both minerals?
No, diamond is a mineral. Coal is an igneous rock; it can take years for coal to form.
How many years does it take for coal to change into a diamond?
It would be highly unusual if coal ever turned into diamond. Diamonds are formed only at depths in the crust of more than 60 miles. Coal on Earth does not exist at anywhere near this depth.
How long does it take to turn coal into a diamond?
A long time
Is burning coal a reversible change?
No, for coal burning to be a reversible change, you would need the ability to take CO2 and turn it back into solid carbon.
How long does it take a piece of coal to become a diamond?
It takes extreme pressure and tens of thousands of years, but, yes, if the conditions are right, a diamond can result. Coal and diamonds (and graphite too!) are all made from purely carbon atoms! They are just different forms of the same element! Pretty amazing, eh?!

What agricultural activites take place in Venezuela?
Gold, fishing, petroleum, coal, forest, diamonds, bauxite, iron ore, and manganese.

How long does it take to coal to renew?
millions of years

What are the causes for depletion of diamonds in India?
Diamonds take millions of years to form. Diamond Mining removes large quantities from the earth in a very short time. It's the same reasons behind the depletion of coal stocks !
How long does it take for coal to renew itself?
millions of years
How are diamonds produced from coal to diamond?
Natural diamonds are produced very deep in the Earth, under great pressure and heat, and some are brought to the surface of the Earth. The carbon source is graphite rather than coal. They also take a long time to grow.Synthetic diamonds are grown in the 'lab' and thin films of diamond produced this way are used in the semiconductor industry as heat sinks under chips. For diamond has the highest thermal conductivity.For more information, see wikipedia.org under diamond, or carbon, or gemstones.
