Energy transformation

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.
