Question

hands moving on a battery - operated clock is an example of what kind of energy conversion?
a. heat energy being converted to gravitational potential energy
b. chemical potential energy being converted to kinetic energy
c. kinetic energy being converted to chemical potential energy
d. gravitational potential energy being converted to heat energy

Explanation:

A battery - operated clock has a battery which stores chemical potential energy. When the clock runs, the hands move which indicates kinetic energy. So, the chemical potential energy in the battery is converted into kinetic energy of the moving hands.

Answer:

B. Chemical potential energy being converted to kinetic energy
