What are 8 examples of energy transformation?

Answer 1

Chemical to chemical, which may emit or absorb heat.

Chemical to electrical (batteries, nerve cells)

Heat to chemical or physical change.

Mechanical to electrical (dynamos, motors, loudspeakers),

Photo-chemical (inc. photosynthesis),

Photo-physical (light-emitting diodes and solar panels),

Piezo-electric (gas-cooker igniters, buzzers, sonar),

Mechanical to sound (sirens, animal voices)

Friction

Potential to kinetic in moving masses.

Nuclear - some fission reactions emit photons of light.

Electrical to magnetic fields (radio).

And many of the above are reversible.

Answer 2

1. Solar energy to electrical energy in photovoltaic cells.
2. Chemical energy to thermal energy in a car engine.
3. Potential energy to kinetic energy in a falling object.
4. Electrical energy to light and heat energy in an incandescent light bulb.
5. Wind energy to mechanical energy in wind turbines.
6. Nuclear energy to electrical energy in a nuclear power plant.
7. Mechanical energy to electrical energy in a generator.
8. Food chemical energy to kinetic energy in human muscles.
