Explanation:

Electrical energy is defined as the energy flowing through a device due to the flow of electrons or charges from one point to another.

The energy present within an object or material due to the sum of its motion and potential energy is known as mechanical energy.

Thermal energy is defined as the energy present within an object because of the motion of its particles.

So, when we plug in and turn on a hair dryer then electrical energy starts to flow. As a result, some of its molecules will gain kinetic energy and some will have potential energy.

Hence, its sum will lead to formation of a mechanical energy. Since, this mechanical energy gets converted into thermal energy due to which hairs get dry.

Thus, we can conclude that the energy transformation that occurs when a hair dryer is plugged in and turned on is that electrical energy transforms into mechanical and thermal energy.

Electrical energy transforms into mechanical and thermal energy.

The correct option is B.

What is the energy transformation?

The energy can not be created nor destroyed, it can only transform from one form to another.

In every process, the energy is changed from one form to another.

In photosynthesis, the heat energy into chemical energy.

When a hairdryer is used, the electric energy is changed into mechanical energy to start the dryer.

The dryer dries the hair so that the mechanical energy in changing into heat energy.

Thus, the correct option is B, Electrical energy transforms into mechanical and thermal energy.
