What is the energy conversion that takes place when an electric blender is plugged in and switched on?
Answer and explanation
Correct answer: A. Electrical energy to mechanical (kinetic) and sound energy
- Step 1: An electric blender draws electrical current from the power mains to spin its electric motor blades. Step 2. The motor transforms incoming electrical energy into rotary kinetic motion to blend food, with sound and heat as secondary byproducts. Answer: Electrical energy to mechanical (kinetic) and sound energy. Why not the others: Chemical to electrical occurs in batteries; solar to thermal occurs in solar heaters; kinetic to chemical does not occur here.
