Give me an example of an energy conversion.

- - Light a candle. Chemical energy stored in the wax

is converted to light and heat.

- - Turn a flashlight on. Chemical energy stored in the battery

is converted to electrical energy, which flows through the wiring

to the light-bulb. As the electric current current flows through the

bulb, electrical energy is converted to light and heat.

- - Plug a fan into a wall outlet. Electric current flows through

the line-cord to the motor, where electrical energy is converted

to kinetic energy. The kinetic energy of the motor is sent to turn

the fan blades, where it is used to move air.

- - Electromagnetic energy from the sun strikes the surface of a

photoelectric cell, where it is converted to electrical energy.
