Final answer:
In a power plant where coal is burnt to generate electrical power, a chemical to electrical energy transformation occurs through a series of processes involving heat and kinetic energy.
Step-by-step explanation:
The correct answer is c) chemical to electrical. In a power plant where coal is burnt to generate electrical power, a chemical reaction takes place between the coal and oxygen, resulting in the release of heat energy. This heat energy is then used to generate steam, which drives a turbine. The rotating turbine converts the thermal energy into kinetic energy, which ultimately gets converted into electrical energy by the generator.
