In a hydroelectric power station, one form of energy is stored in a lake or reservoir. This energy is then transferred in stages to another useful form, which is the output. Which letter gives the stored energy and then the output energy?

• electrical to thermal

• electrical to kinetic

• gravitational to electrical

• kinetic to electrical

The list contains three energy resources.

Q - nuclear fission in reactors

R - sunlight on solar panels

Which of these resources are renewable?

• P and Q only

• P and R only

• Q and R only

• P, Q and R

When a bicycle lamp is switched on, what is the useful energy change within the battery?

• chemical energy to electrical energy

• electrical energy to chemical energy

• electrical energy to light energy

Some energy sources are reliably available at all times, and some are not. Of the three sources, geothermal, solar and nuclear, which are available at all times?

• geothermal only

• geothermal, solar and nuclear

• geothermal and nuclear

An aeroplane is landing. As it descends towards the runway, its speed reduces. What are the energy changes that take place during the descent?

• kinetic + gravitational → thermal (heat)

• kinetic → gravitational + thermal (heat)

• kinetic + thermal (heat) → gravitational

• thermal (heat) → kinetic + gravitational

Energy from uranium is transferred to electrical energy in a nuclear power station. What is the correct order of the stages of this process?

• boiler → generator → reactor → turbine

• generator → boiler → turbine → reactor

• reactor → boiler → turbine → generator

• reactor → turbine → boiler → generator
