Yr 11 Physics - Nuclear Physics

Nuclear power plants rely on which of the following reactions to generate energy?

• Fusion
• Half-life
• Fission
• Fusion or fission

This is an example of...

• Fission  reaction
• Fusion reaction
• Decomposition reaction
• Combustion

What is an advantage  of nuclear energy?

• radioactive waste
• no air pollution
• we will never run out
• it is the safest way to make energy

What controls the reaction within a nuclear reactor?

• Control Rods
• Moderator
• Containment building
• Reactor Vessel

Complete the phrase: 'The longer an element's half-life...'

• ...the longer it will take to decay
• ...the more radioactive it is
• ...the less radioactive it is
• ...the rarer it is

What is coming out of the tops of the cooling towers of a nuclear power plant?

• Carbon dioxide
• water vapor
• Hydrogen oxide
• Pollution

Why have scientists not begun to try and use fusion on Earth?

• Fusion requires too large of a power plant
• Fusion requires extremely cold temperatures not possible on Earth
• Fusion requires extremely hot temperatures that are not possible on Earth
• Fusion requires too much oxygen that we could not survive

If you start out with 100 grams of a radioisotope, how much remains after 2 half-lives?

• 100 grams
• 75 grams
• 50 grams
• 25 grams
