Final answer:
The question asks about specific energy transformations, which are processes where energy changes from one form to another. Examples include converting electrical energy to mechanical and then to thermal, or potential to kinetic then to sound. Additional notable transformations occur with chemical to kinetic energy (e.g., in human movement) and solar to electrical energy (e.g., in solar cells).
Step-by-step explanation:
The student is asking about the transformation of energy in different scenarios, which is a fundamental concept in physics. The transformations described in the options include:
- Electrical to Mechanical, then Mechanical to Thermal as seen in an electric motor heating up as it runs.
- Thermal to Chemical, then Chemical to Electrical which could be illustrated by a thermochemical battery converting heat directly into electrical power.
- Potential to Kinetic, then Kinetic to Sound energy, such as a ball rolling downhill and then crashing, creating sound.
- Sound to Light, then Light to Chemical energy, a more complex transformation that could be exemplified by technologies that convert sound waves into light signals, which could then initiate a chemical reaction.
Additional examples of energy transformation include humans converting the chemical energy in food into kinetic energy to ride a bicycle, and plants converting sunlight (light energy) into chemical energy through photosynthesis. Moreover, a photovoltaic cell transforms solar energy into electric energy, illustrating the solar to electrical energy conversion. Finally, in the combustion of gasoline, chemical energy is converted into mechanical energy that powers a car's engine.
