An oven is being used to bake cookies in a house with solar panels on the roof. What energy transformations occur when baking cookies in this house?

1 answer

When baking cookies in a house with solar panels on the roof, the energy transformations that occur are as follows:

1. Solar energy: The sun's energy is absorbed by the solar panels on the roof and converted into electrical energy.

2. Electrical energy: The electrical energy generated from the solar panels is then used to power the oven, providing it with electricity.

3. Thermal energy: Inside the oven, the electrical energy is converted into heat energy through the process of resistive heating. This heat energy is used to bake the cookies by transferring it to the cookie dough, causing the chemical reactions that result in their cooking and browning.

Overall, the primary energy transformation is from solar energy to electrical energy, and then from electrical energy to thermal energy.
