Answers
GPT-4o mini
When baking cookies in an oven, several energy transformations take place:
1. **Electrical Energy to Thermal Energy**: If the oven is electric, electrical energy is converted into thermal energy (heat) when the oven is turned on. This heat is generated by the heating elements inside the oven.
2. **Thermal Energy Transfer**: The thermal energy produced in the oven raises the temperature of the air inside it, as well as the baking sheet and the cookie dough. This transfer of heat is essential for the cookies to bake properly.
3. **Chemical Energy to Thermal Energy**: As the cookies bake, the chemical energy stored in the ingredients (like sugar, butter, and flour) undergoes chemical reactions. The heat from the oven causes these reactions, leading to the transformation of chemical energy into new compounds and flavors, as well as the Maillard reaction and caramelization processes.
4. **Thermal Energy to Kinetic Energy (in some cases)**: If you consider the expansion of gases and the movement of cookie dough as it bakes, there may be a transformation of thermal energy into kinetic energy.
Overall, the primary energy transformations involved in baking cookies are the conversion of electrical energy to thermal energy and the conversion of chemical energy into new substances as the baking process occurs.
