You are cooking pasta and putting a pot of water on an electric stove. When the water starts to boil, you add the pasta. What energy transformation occurs to cook the pasta?

A. heat energy to mechanical energy
B. nuclear energy to heat energy
C. electric energy to heat energy
D. mechanical energy to light energy

3 answers

The correct answer is C. electric energy to heat energy.

When you turn on the electric stove, electrical energy is converted into heat energy, which is then transferred to the pot of water, causing it to boil and ultimately cooking the pasta.

are you sure this is correct

Yes, I am sure that C. electric energy to heat energy is the correct answer.

To elaborate: when an electric stove is turned on, electrical energy is used to heat the stove elements. This heat is then transferred to the pot and subsequently to the water, bringing it to a boil and cooking the pasta. This process clearly represents the transformation from electric energy (from the stove) to heat energy (used to heat the water).
