Hydrogen because it only gives off water and is easy to make. Petrol is bad for environment and is running out
Edit:
Hydrogen usable as a fuel (H2) may be "easy to make" but the amount of energy you would consume in making the H2 would be greater than the amount of energy you would get back when you burned the H2.
Petrol is called a hydrocarbon because it is primarily composed of molecules containing hydrogen and carbon atoms. The main components of petrol are hydrocarbons such as octane, which is a chain of eight carbon atoms bonded together with hydrogen atoms.
Petrol is primarily composed of hydrocarbons, which are organic compounds made up of carbon and hydrogen atoms. The hydrocarbons in petrol are derived from the remains of ancient marine organisms that were subjected to heat and pressure over millions of years, forming crude oil. Refining processes separate and purify these hydrocarbons to create petrol for use as a fuel.
It really depends on what you are using the fuel for. If you want a liquid fuel that easily vaporizes in a carburetor to make an explosive mixture with air and burns quickly to release a lot of energy, then petrol is better than wax. I you want a less dangerous fuel for a candle, one that melts and vaporizes to burn slowly in air, then wax is what you want. The reason for the different burning properties of petrol and wax lies mainly in the size of their molecules and how the carbon and hydrogen atoms in them are joined together.
In petrol, the combustion of hydrocarbons present is complete and they burn with blue flame. However, in kerosene, the combustion is not complete. It burns with smoky flame accompanied by the release of unburnt carbon atoms. Therefore, petrol is regarded as a better fuel than kerosene.
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.
It's not
less pollution
hydrogen
As hydrogen releases more energy than petrol, H engine is more powerful than petrol .
Petrol
Simple! Hydrogen.
yes it is
oxy-hydrogen
yes ellie bramley does
Petrol is a compound, not an element. It is made up of a mixture of hydrocarbons, primarily containing carbon and hydrogen atoms.
Hydrogen combines with oxygen when burned, forming H2O (water).
2.4 petrol is better than 2.2 TD in my opinion.. I just replaced my 2.3TD with a petrol.. 2.4 petrol is better than 2.2 TD in my opinion.. I just replaced my 2.2TD with a petrol..
