How do you convert chemical to mechanical?

Answer 1

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.

Answer 2

Chemical energy can be converted to mechanical energy by harnessing the energy released during a chemical reaction. This can be achieved using various methods, such as combustion engines, where the chemical energy in fuel is converted into heat energy and then mechanical energy to power vehicles. Alternatively, chemical-to-mechanical energy conversion can also occur in processes like battery-operated devices where chemical reactions inside the battery generate electrical energy, which is then converted into mechanical energy to perform tasks.
