An oven is being used to bake cookies in this house. What energy transformations occur when baking cookies in this house? aheat energy → light energy → chemical energy bheat energy → chemical energy → light energy clight energy → electrical energy → heat energy dheat energy → electrical energy → chemical energy
The correct answer is:
d) heat energy → electrical energy → chemical energy
When baking cookies in an oven, initially, heat energy is transferred from the oven to the cookies, which causes them to bake. This is the first energy transformation, from heat energy to chemical energy in the form of thermal energy in the cookies.
Next, the oven itself converts electrical energy into heat energy. This is the second energy transformation, from electrical energy to heat energy.
Therefore, the correct sequence of energy transformations in baking cookies in this house is:
heat energy → electrical energy → chemical energy.
