Ответ:
An example of electrical energy being converted to chemical energy: D. A storage battery is charged using an electric current.
Further explanationEnergy can be interpreted as the ability to do work
There are several examples of energy
1. Kinetic energy is the energy possessed by objects due to their motionm = mass
v = velocity
2. Potential energy is the energy that an object has because of the location of that object. Usually it is related to the force of gravityg = acceleration due to gravity
h = height
3. Mechanical energy is the sum of kinetic energy and potential energyEnergy can change into other forms of energy but the magnitude will remain the same. This is in accordance with the law of conservation of energy which states that
Energy can change to other forms but cannot be created or destroyed
Let's look at the answer choices
A. The wheels on a machine begin to turn and move a conveyer belt.
the mechanical energy changes into kinetic energy
B. An electric furnace begins to emit heat to warm a house.
the electrical energy changes into heat energy
C. A loudspeaker, which is plugged in to the wall, begins to project sound.
the electrical energy changes into sound energy
D. A storage battery is charged using an electric current.
the electrical energy changes into into chemical energy
