Diamonds. Under extreme pressure and temperature, carbon atoms in coal can rearrange to form diamonds.
Carbon is the element that forms both coal and diamonds. The difference in their structure and properties is due to the conditions under which they are formed - coal forms under low pressure and temperature, while diamonds form under high pressure and temperature.
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.
Coal cannot be turned into diamonds through a simple process. Diamonds are formed deep within the Earth's mantle under extreme pressure and heat over millions of years, whereas coal is formed closer to the Earth's surface under less intense conditions. It is not practically possible to convert coal into diamonds in a laboratory setting.
Hydrogenation of coal is a process that involves reacting coal with hydrogen under high pressure and temperature to produce liquid hydrocarbons such as synthetic fuels. This process can improve the energy content and reduce the emissions associated with burning coal.
They can change into coal

When swamp plants are buried under pressure for a long time, they may eventually transform into coal through a process called coalification. This process involves the decomposition of plant matter under high pressure and temperature, resulting in the formation of coal deposits.
anthracite coal is the metamorphic form of bituminous coal which is the sedimentary form. in other words it has been heated under pressure.
No, coal is not an igneous rock at all. Coal is made from sedimentary rock that is squeezed under the ground by great pressure.
pure carbon is coal, also diamonds are coal that was under a lot of pressure. so both diamonds and coal are pure carbon.

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.
Anthracite coal is a type of metamorphic rock. It forms from the transformation of bituminous coal under increased temperature and pressure over time.
They melt. Coal turns to diamond.

Well it depends on when you mean....Bituminous coal that's mined can be fired in bee oven to produce "Coke", a fuel.Burned Bituminous Coal in a furnace produces clunkers--hard, brittle chunks with coal burned out.When a waste heap of coal catches fire, it produces Reg Dog, a hard, partly brittle rock used as road cover.In the ground, unmined and under pressure and heat, Bituminous coal changes to Anthracite coal.
