Question 12

A hydroelectric power station generates electricity. Water held behind a high dam flows downwards through pipes. The flowing water turns a turbine, causing it to spin, which drives a generator to produce electricity.

Which row gives the name of the energy store of the water held high behind the dam and the energy store of the spinning turbine?

A

Water behind the dam: gravitational potential; Spinning turbine: kinetic

B

Water behind the dam: gravitational potential; Spinning turbine: thermal

C

Water behind the dam: chemical; Spinning turbine: kinetic

D

Water behind the dam: chemical; Spinning turbine: thermal
