Answer 3

Gas and Petrol one in the same word. Actually Petro is short for Petroleum, which is raw unrefined oil.  Gas is a derivative of the Petroleum or a product of it.  Coal is a carbon substance that's created from plants that has been compressed of it's oxygen water content. It's almost has oil properties. Neither is better than the other one is liquid form and the other is hard material. One you can use in your auto and one can be used in a coal fired furnice that heats up water for steam power. Steam of course can be used to keep you warm and it can be used to turn generator turbines.

Answer 4

Gas and Pertrol are the same.  

It depends on what your definition of 'better' is.  All can be burned without much pollution outside of CO2.  Coal is by far the cheapest, however it isn't practicle for automobiles (you won't be filling up a coal hopper).  You also won't see gasoline power plants because of the cost gasoline is much higher than coal.  Coal plants will generate the same amount of electricity for less money, and have the same efficiency as gas since power plants all use a steam cycle.

I guess you could make the argument that coal is best, since the electricity generated can power trains, which will get you from point A to B much as a car will.  It will be cheaper and have an effciency similar to gasoline.  

There is also the national security argument for coal when it comes to the UK and America.  America and the UK have vast coal reserves, and don't have to rely on any foreign countries for supply.
