When baking cookies in an oven, several energy transformations occur:
1. **Electrical Energy to Thermal Energy**: If the oven is electric, it converts electrical energy from the power source into thermal (heat) energy when the heating elements or convection fans are activated.
2. **Thermal Energy Transfer**: The thermal energy produced by the oven is transferred through the air inside the oven and directly to the cookie dough. This heating process causes the dough to bake.
3. **Chemical Energy to Thermal Energy**: As the cookies bake, the chemical energy stored in the ingredients (like sugars and fats) is transformed into thermal energy through the baking process. This includes the Maillard reaction and caramelization, which contribute to the cookies’ flavor and texture.
4. **Kinetic Energy**: If you consider the mixing process before baking, the mechanical energy (kinetic energy) from stirring or mixing the dough transforms into thermal energy through friction.
These transformations ultimately result in the cookies being baked and ready to consume.
