Energy Transformations

Energy transformations refer to the process of changing energy from one form to another, such as electrical energy to thermal energy.

The law of conservation of energy states that energy is never created nor destroyed; it can only be transformed from one form to another.

In a lamp, the energy transformation is electrical → thermal → light.

In a toaster, the energy transformation is electrical → thermal.

Sunlight becomes chemical energy when converted by plants during photosynthesis.

An example is a fan converting electrical energy into kinetic energy to create airflow.

During energy transformations, energy can change forms but the total amount of energy remains constant.

No, according to the law of conservation of energy, energy cannot be created or destroyed.

Thermal energy is the energy that comes from the temperature of matter; it is the total kinetic energy of particles in an object.

Chemical energy is the energy stored in the bonds of chemical compounds, like food or fuel.
