Nuclear Fission Quiz

What is nuclear fission?

• The combination of small nuclei into a larger nucleus

• The splitting of a large nucleus into smaller nuclei

• The process of converting nuclear energy into chemical energy

• The absorption of neutrons by a stable nucleus

How does nuclear fission release energy?

• By absorbing energy from the environment

• By converting chemical energy into nuclear energy

• By splitting nuclei and releasing gamma radiation

• By combining nuclei to form a larger nucleus

What role do neutrons play in nuclear fission?

• They stabilize the nucleus

• They make the nucleus more stable

• They split the nucleus by making it less stable

• They convert nuclear energy into thermal energy

What is a chain reaction in nuclear fission?

• A process where one fission event triggers additional fission events

• A process where fission stops after one event

• A process where energy is absorbed by the nucleus

• A process where neutrons are absorbed without causing fission

What is a potential risk of nuclear fission if not controlled properly?

• The reaction will stop immediately

• The system can release huge amounts of energy uncontrollably

• The system will produce no energy

• The system will convert all energy into chemical energy

What is one method to control the rate of fission in nuclear reactors?

• Increasing the temperature

• Lowering control rods to absorb neutrons

• Adding more uranium fuel

• Removing all neutrons from the reactor

What is the energy released from nuclear fission used for in power plants?

• To heat up water and turn it into steam

• To cool down the reactor

• To produce chemical energy

• To absorb more neutrons

What is a pro of using uranium or plutonium fuel in nuclear energy?

• It is classified as renewable energy

• It is relatively cheap and produces a large amount of energy

• It produces greenhouse gases

• It is expensive to produce

What is a con of nuclear power plants?

• They are inexpensive to build

• They produce no waste

• They are very expensive to build

• They produce renewable energy

Why are people suspicious of using nuclear energy?

• Because it is a renewable energy source

• Because of the risk of a major disaster if the plant malfunctions

• Because it produces no energy

• Because it is the cheapest energy source
