Mechanical energy
Coal is a chemical compound which contains chemical energy. To convert coal into mechanical energy, you use it (burn it) to produce heat and use the heat to boil water, the steam from which will drive a steam engine which delivers mechanical energy.
The chemical energy is transformed in kinetic energy.
: the engine changes chemical energy into light and kinetic energy to power the car? Write your answer...
Energy can only really be changed into other forms of energy. However, you can use energy to generate force, pressure, torque, etc. For example, when gasoline is burned in a car engine, chemical energy gets converted into mechanical energy (sort of like force times speed).
Assuming you are refereeing to a physical engine not one of the software variety. Its to propel motor vehicles. Next time Phrase your question better and then you will get a better anwser.
Into heat.
Chemical energy is energy produced by chemical reactions. Burning gasoline is one example. The reactions of materials in a battery that produce electricy are another. There are many such examples. Mechanical energy is energy of a mechanical system, such as a motor or engine. Examples are the automobile, the electric motor. and so on. Converting chemical energy to mechanical energy is what makes a car go.
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.

Coal is a chemical compound which contains chemical energy. To convert coal into mechanical energy, you use it (burn it) to produce heat and use the heat to boil water, the steam from which will drive a steam engine which delivers mechanical energy.
Usually, chemical energy from the fuel. In an electric vehicle, electric energy from the battery.
A gasoline engine converts chemical energy into mechanical energy.
Such an engine is used mainly to convert the chemical energy of the petrol into kinetic energy for various applications. And indeed it does that, but it also converts a considerable amount of the chemical energy into heat, which is generally of no use at all and must be vented into the passing air in order to avoid melting the engine.
Energy conversion is the changing of one form of energy into another or into work, such as that in the combustion process.
A combustion engine converts chemical energy in gasoline to mechanical energy in the engine.
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.
If you mean the use of fossil fuels, yes. Typically, the fuels are burned (for example, in a car engine), converting the chemical energy into heat. Part of this is then converted into movement. A heat engine can only convert part of the heat energy into useful energy, so the remainder is wasted.
