Energy: Forms, Transformation, Transfer, and Conservation
Item RG196001: Chemical energy is transformed into kinetic energy (motion energy) in a battery operated watch.
A woman places a new battery in a watch. A chemical reaction takes place inside the battery that causes the hands on the watch to move.
Which of the following describes how energy changes while the watch hands move?
- Kinetic energy (motion energy) is created by the movement of the watch hands.
- Kinetic energy (motion energy) is transformed into chemical energy.
- Chemical energy is transformed into kinetic energy (motion energy).
- Energy does not change because chemical reactions transform matter not energy.
