Question 334

In a hydroelectric power station, water stored behind a high dam flows down through pipes. This flowing water spins a turbine, which turns a generator to produce electricity.

Which terms describe the energy stored in the water in the high reservoir and the energy of the spinning turbine?

A

Water in reservoir: gravitational potential; Turbine: kinetic

B

Water in reservoir: chemical; Turbine: kinetic

C

Water in reservoir: gravitational potential; Turbine: electrical

D

Water in reservoir: chemical; Turbine: electrical
