It is usually used for generation of electric power.
2020-4-4 · The basic difference between coal and coke is that coal is the natural source and coke is the derivative product produced by destructive distillation. Both are used as fuel, but coke contains a higher carbon content and few impurities. Coke is also used during iron ore smelting as a reducing agent. Coal is a naturally-found fossil fuel that is ...

The chemical energy released as the coal is burned heats water and turns it into steam. The chemical energy causes the liquid water molecules to move faster increasing their thermal energy. 2. Gasoline is burned in a car engine. As the gas burns, small explosions release heat or thermal energy which makes the pistons move so the car go. 3.
2021-9-1 · Soft coal is also known as brown coal or lignite. China produces more hard coal than any other country by a factor of about three. The whopping 3,162 million metric tons of hard coal produced by China dwarfs the output of the second and third-ranked …
Metallurgical (met) coal (or coking coal) is a naturally occurring sedimentary rock found within the earth''s crust.
