An oven is being used to bake cookies in this house. What energy transformations occur when baking cookies in this house?
(1 point)
Responses
light energy → electrical energy → heat energy
light energy → electrical energy → heat energy
heat energy → chemical energy → light energy
heat energy → chemical energy → light energy
heat energy → light energy → chemical energy
heat energy → light energy → chemical energy
heat energy → electrical energy → chemical energy
heat energy → chemical energy → light energy
is that correct
double check
Apologies for the confusion. Let's double check the energy transformations that occur when baking cookies in an oven in this house:
heat energy → chemical energy → light energy
When the oven is turned on, electrical energy is converted into heat energy. This heat energy then causes the chemical reactions in the dough, leading to the formation of cookies. As the cookies bake, the chemical energy stored in the dough is transformed into light energy as the cookies begin to brown.
So, the correct answer would be:
heat energy → chemical energy → light energy
Hydroelectric dams work by blocking the path of a water source to create an area with water held back by the dam. The dam can then be opened to allow water to be released.. The energy from the moving water is used and transformed into electrical energy. What type of energy does a hydroelectric dam capture as the water passes through?(1 point)

The correct answer is heat energy → chemical energy → light energy.
When baking cookies in an oven, the oven primarily uses heat energy to raise the temperature of the cookies and cause them to bake. This heat energy is transferred from the oven to the cookies, leading to a chemical reaction within the cookies called the Maillard reaction. This chemical reaction transforms the ingredients in the cookies, such as flour, sugar, and butter, into a new form, which is chemical energy.
As the cookies continue to bake, the chemical energy stored in the cookies is further transformed into light energy. This occurs as the sugars in the cookies caramelize, creating a golden brown color. The light energy is then emitted as visible light, giving the cookies a visually appealing appearance and indicating that they are fully baked.
The correct answer is:
heat energy → chemical energy → light energy
When baking cookies in an oven, the following energy transformations occur:
1. Heat energy → The oven uses electrical energy to generate heat. This heat energy is transferred to the cookies and is responsible for the baking process.
2. Chemical energy → The cookies contain stored chemical energy in the form of carbohydrates, fats, and proteins. As the heat from the oven is applied to the dough, chemical reactions occur within the ingredients, causing them to undergo certain changes, such as caramelization and Maillard reactions. This chemical energy is converted into other forms of energy during the baking process.
3. Light energy → As the cookies bake, they may undergo browning on the surface. This browning is a result of the Maillard reaction, which is a chemical reaction between amino acids and reducing sugars in the dough. The energy released during this reaction is in the form of light, giving the cookies a golden-brown color.
Therefore, the energy transformations that occur when baking cookies in this house are heat energy being transformed into chemical energy and then into light energy.
