An oven is being used to bake cookies in this house. What energy transformations occur when baking cookies in this house?
a
heat energy → light energy → chemical energy
b
heat energy → electrical energy → chemical energy
c
heat energy → chemical energy → light energy
d
light energy → electrical energy → heat energy
b
heat energy → electrical energy → chemical energy
The correct answer is:
b) heat energy → electrical energy → chemical energy
To determine the energy transformations that occur when baking cookies in this house, there are a few steps you can follow:
Step 1: Identify the initial source of energy. In this case, the solar panels provide the energy.
Step 2: Determine the type of energy provided by the solar panels. In the given picture link, it is mentioned that the solar panels power all appliances in the house. Therefore, the energy from the solar panels is most likely in the form of electrical energy.
Step 3: Consider the oven and the process of baking cookies. The oven uses electrical energy to generate heat, which is necessary to bake the cookies.
Step 4: Identify the energy transformations that occur.
Option a: heat energy → light energy → chemical energy
This option does not accurately represent the energy transformations during cookie baking. While there might be some light energy in the form of visible light emitted by the oven, it is not directly involved in the energy conversion during baking.
Option b: heat energy → electrical energy → chemical energy
This option accurately represents the energy transformations during cookie baking. The solar panels provide electrical energy, which is converted into heat energy by the oven. The heat energy is utilized in the chemical process of baking the cookies.
Option c: heat energy → chemical energy → light energy
This option is not correct. It suggests that chemical energy is converted into light energy, which is not necessary for the process of baking cookies.
Option d: light energy → electrical energy → heat energy
This option does not accurately represent the energy transformations during cookie baking. While the solar panels initially convert light energy into electrical energy, the oven does not directly convert light energy into heat energy.
Therefore, the correct answer is option b: heat energy → electrical energy → chemical energy.
