Answer:
C. Burning a log in a fireplace
Step-by-step explanation:
Chemical energy is stored in the bonds between atoms and molecules and can be converted into another form of energy. This can occur through chemical reactions, such as combustion or decay.
An example of chemical energy being converted into another form is option C: Burning a log in a fireplace. In this example, the chemical energy stored in the wood is released through combustion, producing heat and light. The heat energy is then transferred to the surrounding air and environment, warming it up.
This is different from options A and B, which involve physical changes but not the conversion of chemical energy. Option D, a roller coaster going downhill, is an example of potential energy being converted into kinetic energy, but not of chemical energy being converted.
