What type of energy transformation takes place when carbon is cycled in a coal-based power plant?

Chemical energy to chemical energy

Chemical energy to electrical energy

Mechanical energy to chemical energy

Mechanical energy to mechanical energy

Let us see the initial state; the energy that is used in the start is within carbon and it is in the form of chemical bonds that make the molecules; this energy is lost from carbon molecules as they are transformed into carbon dioxide and vapor. This energy then takes the form of electricity since we are talking about a power plant that supplies energy. Hence, the correct answer is chemical to electrical.
