Explain how the Law of Conservation of Energy applies to the energy transformations that occur from the outlet charger to the ringing phone.

The mobile electric energy gets converted into chemical energy while charging.

Explanation:

According to the law of conservation of energy, no energy is destroyed when one form of energy is transformed to another in the process as energy cannot be created or destroyed. As a result, total amount of energy remains same before and after any kind of transformation.

Generally, lithium ion batteries are used in mobile phones. In such batteries, the electricity is stored in the ionic structure by the chemical changes.

The mobile electric energy gets converted into chemical energy while charging.
