The energy transformation process for Joshua to bake cookies in the oven using solar panels can be described as follows:
1. Solar Energy to Electrical Energy: The solar panels convert sunlight (solar energy) into electrical energy through the photovoltaic effect. When sunlight strikes the solar panels, the photons in the sunlight generate an electric current in the solar cells.
2. Electrical Energy to Electricity Supply: The electrical energy produced by the solar panels is then transformed into a usable and stable electricity supply. This involves the use of inverters that convert the direct current (DC) electricity produced by the solar panels into alternating current (AC) electricity, which is the type used by household appliances.
3. Electricity Supply to Oven: The electricity from the solar panels (converted to AC) is then directed to the oven through the electrical system of Joshua's house. The electrical current powers the heating element of the oven, which converts electrical energy into heat energy.
4. Heat Energy to Baking: The heat energy generated by the heating element of the oven is then utilized to bake the cookies. The heat energy is transferred to the baking chamber, where it heats up the air inside. As a result, the cookies gradually cook and become ready for consumption.
In summary, the solar panels transform solar energy into electrical energy, which is then converted into a usable electricity supply. This electricity is used to power the oven's heating element, which converts electrical energy into heat energy for baking the cookies.
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 cook ones for his family in the oven
