Which substances is obtained by heating coal in absence of air?
When coal is heated in the absence of air, it undergoes a process called destructive distillation or pyrolysis, resulting in the formation of substances such as coal gas, coal tar, and coke.
Why must coal be heated in the absence of air to change into coke?
Coal needs to be heated in the absence of air to turn into coke because oxygen in the air would react with the coal and burn it, preventing the transformation into coke. Heating the coal in the absence of air allows the volatile components to be driven off, leaving behind a more solid and pure carbon structure, which is coke.
How is coal turned into coke?
Coal is turned into coke through a process called coking. In this process, coal is heated in the absence of air to high temperatures, causing it to undergo thermal decomposition. This transforms the coal into a solid carbon material known as coke, which is used in industrial processes like steel manufacturing.
How coal tar is formed?
Coal tar is formed during the process of coal gasification or coking, where coal is heated in the absence of air to produce coal gas and other byproducts. The tar is a dark, thick liquid that contains various hydrocarbons and is collected as a byproduct of these processes.
What is carbonization of coal?
Carbonization of coal is a process where coal is heated in the absence of air to produce coke, which is a hard, porous substance mainly composed of carbon. This process removes volatile components, such as water, methane, and tar, leaving behind a high-carbon product that is used in industrial applications, such as steelmaking.

What is metallurgical coke?
when bituminous coal is heated stronly in the absence of air,the volatile matter escapes out and the mass becomes hard,strong,porous and coherent which is called Metallurgical coke.

What is coal carbonization?
Coal carbonization is a process where coal is heated in the absence of air to produce coke, a fuel used in steel manufacturing and other industrial processes. This process involves the conversion of coal into different byproducts like coke, coal gas, and coal tar. It helps to increase the energy content and purity of coal, making it more suitable for certain applications.
How is it produced coke from coal?
Coke is produced from coal through a process called destructive distillation. In this process, coal is heated in the absence of air to drive off volatile components, leaving behind coke. The coke produced is a porous material that is used as a fuel and as a reducing agent in the smelting of iron ore.
What happens when ZnCO3 is heated in the absence of air?
ZnCO3, when heated in the absence of air, decomposes to give ZnO and CO2. I think this is the answer.
What will happen when coal is burned in the absence of air?
It will not burn.
Is their a word for absence of air?
the absence of air is "vacuum"
What happens when sulphur is heated in absence of air?
Sulfur is melted.
