Energy transformations

Everyday, we produce transformations of energy. When energy is transfomed, it may produce some unwanted forms of energy. The following examples show how:

👉When we rub our hands , we transformed the chemical energy in our muscles into kinetic energy, and after, the kinetic energy can be transformed into thermal energy.

👉The chemical energy in the fireworks is converted into light, heat , sound and mechanical energy when it explode.

👉The nuclear energy in stars is transformed into very intense luminous and thermal energy.
