The picture shows solar panels that power all appliances in this house.
An oven is being used to bake cookies in this house. What energy transformations occur when baking cookies in this house?
heat energy → chemical energy → light energy
heat energy → electrical energy → chemical energy
heat energy → light energy → chemical energy
light energy → electrical energy → heat energy
heat energy → chemical energy → light energy
The correct energy transformations that occur when baking cookies in this house are:
1. Heat energy → Electrical energy: The solar panels generate electricity by converting sunlight into electrical energy.
2. Electrical energy → Heat energy: The electrical energy powers the oven, which converts it into heat energy to bake the cookies.
So, the correct sequence of energy transformations is:
Heat energy → Electrical energy → Heat energy.
