Which of the following is an example of electrical energy being converted to chemical energy?

AA loudspeaker, which is plugged in to the wall, begins to project sound.
BA storage battery is charged using an electric current.
CThe wheels on a machine begin to turn and move a conveyer belt.

Verified Answer :

Answer : The correct option is, (B)

Explanation :

Electrical energy : It is defined as the movement of the electrons thought the wire.

Chemical energy : It is a type of energy which is stored in the bonds of a chemical compounds. During the chemical reaction, chemical energy is released in the form of heat.

Sound energy : It is a type of energy which is produced when an object vibrate.

Mechanical energy : It is a type of energy that can be used to do work.

The option A is incorrect because in this process, electrical energy being converted to the sound energy.

The option B is correct because in this process, electrical energy being converted to chemical energy. An oxidation-reduction reaction occurs in the storage battery.

The option C is incorrect because in this process, mechanical energy being converted to mechanical energy.

Hence, the option (B) A storage battery is charged using an electric current is an example of electrical energy being converted to chemical energy.

Answer: 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.
