You are solid substance left after heating coal or petrol?
Heating coal leaves the solid 'coke' , which is impure carbon , and used in blast furnaces for iron ore reduction to iron. Heating petrol will create a vapour which may spontaneously ignite. The solid left behind is carbon (soot).
How petrol is made from coal?
Petrol is not directly made from coal, but rather through a process called coal liquefaction. In this process, coal is converted into a liquid form by heating it at high temperatures and pressures with hydrogen. The resulting liquid can then be refined to obtain fuels like petrol. However, coal liquefaction is not commonly used due to its high cost and environmental concerns.
