Which of the following is an example of electrical energy being converted to chemical energy?
a. a loudspeaker, which is plugged in to the wall, begins to project sound.
b. a storage battery is charged using an electric current.
c. the wheels on a machine begin to turn and move a conveyer belt.

Option (B) is the correct answer.

Explanation:

Electric energy is defined as the energy generated due to the movement of electrons through a wire or solution.

Whereas chemical energy is the energy present within the bonds of a chemical compound. When a chemical reaction takes place then if chemical energy is released then it will be in the form of heat.

So, when a storage battery is charged using an electric current then it means electric energy is being converted into chemical energy.

And, when a loudspeaker, which is plugged in to the wall, begins to project sound then electrical energy is being converted into sound energy.

Whereas when the wheels on a machine begin to turn and move a conveyer belt then work is being done. This means that electric energy is being converted into mechanical energy.

Thus, we can conclude that a storage battery is charged using an electric current is an example of electrical energy being converted to chemical energy.

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.
