What is the purpose of the turbine in a power station?
  • To burn the fuel
  • To boil the water
  • To turn the generator
  • To generate the electricity
In a power station using a fossil fuel or biofuel, what is the energy transfer?
  • Chemical to electrical
  • Nuclear to electrical
  • Heat to electrical
  • Kinetic to electrical
In a nuclear power station, which of the following represents the sequence of energy transfers in the correct order?
  • Nuclear → heat → kinetic → electrical
  • Chemical → nuclear → heat → kinetic → electrical
  • Chemical → nuclear → heat → electrical
  • Nuclear → kinetic → electrical
To which of the following environmental issues does burning fossil fuels to generate electricity contribute?
  • Acid rain
  • Global warming
  • Smog
  • Ozone depletion
Which of the following is also released when fossil fuels are burnt?
  • Methane and soot
  • Nitrogen
  • Sulfur dioxide and soot
  • Hydrocarbons
In a nuclear fuel, where is the energy released from?
  • From the electrons
  • From reactions between atoms
  • From the effects of vibrations of the atoms
  • From changes in the nucleus
Which of the following power stations has the start up time?
  • Nuclear
  • Coal fired
  • Oil fired
  • Gas fired
Although nuclear fuel is relatively cheap, electricity from nuclear power stations is relatively expensive. Why?
  • They need to be built to high safety standards to ensure that no radioactive material escapes
  • Dealing with the used nuclear fuel requires special reinforced containers
  • It is very difficult to safely decommission (dismantle) them at the end of their useful life
  • All of the above

  • Oxidation
  • Combustion
  • Fission
  • Fusion
