Question

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

Answer 1

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.

Answer 2

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.
