"Which of the following describes the energy transformations that occur when a toaster is used to make toast?
A. Thermal energy is transformed into chemical energy in the toaster, and chemical energy is transformed into thermal energy in the toast.
B. Electrical energy is transformed into thermal energy in the toaster, and chemical energy is transformed into thermal energy in the toast.
C. Light energy is transformed into thermal energy in the toaster, and thermal energy is transformed into chemical energy in the toast.
D. Electrical energy is transformed into thermal energy in the toaster, and thermal energy is transformed into chemical energy in the toast."

Step 1: Identify the energy transformations taking place when using a toaster.
The toaster operates on electrical energy, which is converted into thermal energy to heat the coils. This thermal energy is then transferred to the bread, converting it into thermal energy as well. The bread gets hot and toasted as a result.
Step 2: Analyze each option and determine which one accurately describes the energy transformations.
Option A is incorrect because chemical energy is not involved in this process. Option B is correct, as electrical energy is transformed into thermal energy in the toaster. Option C is incorrect because light energy is not involved in this process. Option D is almost correct, but thermal energy is not converted into chemical energy in the toast.
Final Answer
B. Electrical energy is transformed into thermal energy in the toaster, and chemical energy is transformed into thermal energy in the toast. (Although the last part is not entirely accurate, it is the closest option provided.)
