The picture illustrates the solar planets that power all the appliances in Joshua’s house. What energy transformations occur that enable Joshua to bake cookies

1 answer

To bake cookies using the energy harnessed from solar panels, several energy transformations occur. Here's a breakdown of the process:

  1. Solar Energy to Electrical Energy:

    • The solar panels on Joshua’s house capture sunlight, which is a form of solar energy. This sunlight is then converted into electrical energy through photovoltaic cells in the solar panels.
  2. Electrical Energy to Thermal Energy:

    • The electrical energy generated is used to power various appliances in the kitchen, such as the oven. When the oven is turned on, the electrical energy is converted into thermal energy (heat) through electric heating elements.
  3. Thermal Energy for Baking:

    • The thermal energy generated in the oven raises the temperature inside it, cooking the cookie batter through a process known as convection, conduction, and radiation. This heat facilitates the chemical reactions necessary to bake the cookies.

In summary, the energy transformations involved in Joshua baking cookies include the conversion of solar energy to electrical energy and then from electrical energy to thermal energy.
