• 6

What is a disadvantage of nuclear fission as a source of energy?

• Nuclear power stations are expensive to build.

• Nuclear power stations are unreliable.

• Nuclear power stations can only provide small quantities of energy.

• Nuclear power stations release large quantities of carbon dioxide into the atmosphere.

Which source of energy is not currently used to generate electrical energy?

• nuclear fusion

• solar

• tidal

• waves

Electrical energy may be obtained from nuclear fission. In which order is the energy transferred in this process?

• nuclear fuel → generator → reactor and boiler → turbines

• nuclear fuel → generator → turbines → reactor and boiler

• nuclear fuel → reactor and boiler → generator → turbines

• nuclear fuel → reactor and boiler → turbines → generator

Which energy resource has the Sun as its only source of energy?

• geothermal

• nuclear

• oil

• tidal

This question is about four methods used to produce electrical energy. Which method has a correct description?

A stream flows out of a lake and down the side of a hill. What best describes the change in energy stores?

• kinetic energy → chemical energy + internal energy

• gravitational potential energy → kinetic energy + internal energy

• gravitational potential energy + kinetic energy → internal energy

• kinetic energy → internal energy + gravitational potential energy

Energy resources are often used to turn a generator to produce electrical energy. From which resource can electrical energy be produced without turning a generator?

• radiation from the Sun

• uranium by nuclear fission

• water behind a dam

• wind
