You use a battery to power a small hand-held fan to keep cool in the summer what way is the energy transformed?

Chemical to electrical to kinetic energy

Explanation:

In a battery-operated fan, first, the chemical energy stored in the battery is converted to electrical energy within the fan and then the electrical energy, in turn, is converted to kinetic energy which makes the blades of the fan rotate. The rotation of the fan creates a breeze that forces the evaporation of sweat molecules from the surface of the skin and causes cooling in return.
