A city gets its electricity from a dam, where water is stored in a
reservoir. How does the water provide the city with its power?
Mechanical energy in the water is transferred to turbines that spin a
generator, which changes the mechanical energy into electricity.
Kinetic energy in the water becomes potential energy as the water
moves through turbines, where kinetic energy becomes mechanical
energy that spins a generator.
Chemical energy in the water becomes thermal energy as it moves
through turbines, which change thermal energy into electricity.
Potential energy in the water becomes kinetic energy as it moves
through turbines, which turn kinetic energy into mechanical energy
that spins a generator, which changes mechanical energy into
electricity.
The correct answer is:
Kinetic energy in the water becomes potential energy as the water moves through turbines, where kinetic energy becomes mechanical energy that spins a generator.
