Question

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

Answer 1

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

Further explanation

Energy 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 motion

$\displaystyle E_k=\frac{1}{2}mv^2$

m = 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 gravity

$\displaystyle Ep=mgh$

g = acceleration due to gravity

h = height

• 3. Mechanical energy is the sum of kinetic energy and potential energy

$\displaystyle Em=Ep+Ek$

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

Answer 2

The correct answer is option D, that is, a storage battery is charged using an electric current.  

The transformation of one form of energy into another, generally to transform the energy into more useful kind is known as energy conversion. The energy can neither be created nor be destroyed, it can only be transformed. The different forms of energy comprise light, heat, mechanical, electrical, sound, nuclear, and sound.  

In the given question, the charging of a storage battery using electric current is an example of electrical energy being converted into chemical energy.
