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.
The solid substance left after heating coal is called coal ash, while the residue left after heating petrol is known as petroleum coke. These solid substances are byproducts of the heating process and can vary in composition depending on how the coal or petrol was processed.
You are likely to be either coke (from coal) or carbon residue (from petrol). These solid substances are left behind when coal or petrol is heated in the absence of oxygen, which removes volatile components and leaves behind a carbon-rich material.
The substance left after heating coal is coal ash. The substance left after heating petrol is a residue called coke. Both of these byproducts are typically composed of carbon and other elements.
No, coal is not made out of crude oil. Coal is a solid fossil fuel that is formed from the remains of plants that lived millions of years ago, while crude oil is a liquid fossil fuel formed from the remains of marine plants and animals.
The solid substance left after heating coal is called coal ash, which contains minerals and impurities present in the coal. The solid substance left after heating petrol is a residue of carbon known as petcoke, which is used as a fuel source in some industries.
petrol is extracted from crude oil
cook the coal in a oven without air and distill the gas , its called cracking and you have crude petrol
Petrol can ignited easier than coal. Coal fired cars would be far too slow and also they would be alot of hassel.

To conserve the environment.

because coal has more energy intake ?..,

Petrol is better fuel for cars than coal because coal is a solid therefore it has to be transported by lorries or trains, releasing carbon dioxide and other harmful emissions. Petrol however is a liquid and can be transported in tankers or sent through pipes. Furthermore, coal releases less energy than petrol.Additional answerIt would be fair to say that petrol is more efficient than coal in energy conversion terms. It's also less dirty (imagine your Mum filling up at a coal station!)
