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

An example of electrical energy being converted to chemical energy: D. A storage battery is charged using an electric current.

Energy can be interpreted as the ability to do work

There are several examples of energy

m = mass

v = velocity

g = acceleration due to gravity

h = height

Energy 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
