Why do cars only run on petrol/Diesel oil ?!?
Hi, There are different kinds of energy. One is the energy that something has when it is in motion. Another is the energy something has when it is at rest. Energy can be on the physical level like a boxer’s punch or in a mother rocking her child. It can be on the molecular level so that when we pour peroxide on to baking soda it fizzes up or when you burn a piece of paper it produces light and heat. And it can be on the atomic level where breaking or combining atoms releases energy in several forms. A car needs energy to go. That energy is found in the burning of the fuel to produce not only heat but pressure as the fuel is burned in the form of an explosion in the cylinders of a car. The ideal fuel has to be stable enough to move around, holds a lot of trapped energy that is easily available and it has to be common enough so that it is relatively cheap. Carbon is a very common element and it combines with oxygen easily to produce carbon dioxide. Petrochemicals came from plants that in
