Question

The picture illustrates the solar panels that power all of the appliances in Joshua's house. What energy transformations occur that enable Joshua to bake cookies for his family in the oven?
light energy → electrical energy → chemical energy
light energy → electrical energy → chemical energy

heat energy → light energy → heat energy
heat energy → light energy → heat energy

heat energy → chemical energy → light energy
heat energy → chemical energy → light energy

light energy → electrical energy → heat energy

Answer 1

To bake cookies using the oven powered by solar panels, the relevant energy transformations are:

**Light energy → electrical energy → heat energy**

- **Light energy** from the sun is captured by the solar panels and converted into **electrical energy**.
- This electrical energy is then used to power the oven, creating **heat energy** which is necessary for baking cookies.

Thus, the correct transformation sequence is **light energy → electrical energy → heat energy**.
