Which energy transformation happens when a toaster is plugged in to an outlet in the wall and used to make toast

When a toaster is plugged in to an outlet in the wall and used to make toast, the energy transformation that occurs is:

1. Electrical energy from the outlet is transformed into thermal energy in the heating elements of the toaster.
2. The thermal energy then conducts into the bread slices, resulting in the transformation of thermal energy into heat energy in the bread.
3. As the heat energy increases, the moisture in the bread evaporates, leading to the transformation of heat energy into chemical potential energy due to the chemical reactions occurring in the bread.
4. Finally, the chemical potential energy is transformed into radiant energy (light and heat) as the bread toasts, and this energy is then emitted into the surroundings.

Overall, the energy transformations involved in the process from plugging in the toaster to making toast are electrical energy → thermal energy → chemical potential energy → radiant energy.
