Energy conversion is the changing of one form of energy into another or into work, such as that in the combustion process.
The cars internal combustion engine converts the stored chemical energy of gasoline to motion and heat.
yes
gasoline is matter, it is burned to create energy
The energy released from gasoline when it is used in a gasoline engine is chemical energy.
The chemical energy stored in the gasoline. Or more precisely, the gasoline and oxygen in the air, separately, have more energy than after they combine.
No. A lot of the energy in the gasoline is wasted.
fire energy
Into heat.
According to Wikipedia, "Gasoline contains about 42.4 MJ/kg ... Gasoline blends differ, and therefore actual energy content varies... by up to 4% more or less than the average" Please note that that's the energy content per kilogram of gasoline; only a fraction of this is converted into useful energy in a car engine.
yes
In a word, No... The energy content stays the same.
There are many examples of how chemical energy can be transformed into mechanical energy. Perhaps the best known example is the combustion of gasoline in an engine to power an automobile.
No
No, it list the energy content in calories, which is the amount of energy to raise a quantity of water by a certain temperature.
An automobile IS not energy; it merely USES energy.
Gasoline is (or at least was) an abundant source of energy. Combustion of gasoline is an exothermic reaction that releases a significant amount of energy that can be harnessed. It's also cheap compared to other fuel sources, and has one of the highest energy return on investment (EROI - how much energy do you get based on how much you invest) ratings.
A soccer ball eventually stops because its energy disappears. When a light bulb is turned on, electrical energy is converted to light and heat. An automobile engine burns gasoline to converts its chemical energy to electrical energy.
I don't think it would be practical. Usually you would try to make gasoline, or a substitute, out of something that actually has a significant energy content. Otherwise, you would need to invest a lot of energy in the conversion.
