In a fossil fuel power station, energy is stored in a fuel such as coal or natural gas. This energy is then transferred in stages to another useful form, which is the main output.
Which row in the table correctly identifies the name of the stored energy and the name of the main useful output energy?
| Stored energy | Output energy | |
|---|---|---|
| A | chemical | electrical |
| B | thermal | electrical |
| C | chemical | thermal |
| D | electrical | kinetic |
