Nuclear Fission and Fusion

What is the significance of the sun's core temperature for fusion?

• It allows for the formation of sunspots.

• It is around 5 million degrees Celsius, which is sufficient for fusion.

• It is crucial for providing the energy needed for nuclear fusion to occur.

• It prevents the sun from collapsing under its own gravity.

What is a common application of nuclear fission?

• In nuclear power plants to generate electricity.

• In medical imaging techniques.

• In the production of fossil fuels.

• In the manufacturing of plastics.

What is a common application of nuclear fusion?

• In hydrogen bombs and potentially in future fusion reactors for energy production.

• In traditional nuclear power plants for electricity generation.

• In the production of nuclear waste management systems.

• In the development of solar panels for renewable energy.

What are the byproducts of nuclear fission?

• Smaller nuclei (fission fragments), neutrons, and a large amount of energy.

• Carbon dioxide and water vapor.

• Helium and hydrogen gas.

• Ozone and sulfur dioxide.

What is nuclear fission?

• A process where an atom's nucleus splits into smaller nuclei, releasing energy.

• A method of combining two atomic nuclei to form a heavier nucleus.

• A type of chemical reaction that occurs in the presence of heat.

• A phenomenon where electrons are emitted from an atom.

What is the process of chain reaction in nuclear fission?

• A process where fission events occur independently without any interaction.

• A chain reaction in nuclear fission occurs when the products of one fission event cause additional fission events.

• A method to control nuclear reactions by absorbing neutrons.

• A reaction that only occurs in fusion processes, not fission.

What are the safety concerns associated with nuclear fission?

• The potential for nuclear accidents, radioactive waste management, and proliferation of nuclear weapons.

• The benefits of nuclear energy in reducing carbon emissions.

• The use of nuclear fission in medical applications.

• The cost-effectiveness of nuclear power compared to renewable energy sources.

What is the role of neutrons in nuclear fission?

• Neutrons can initiate a fission reaction by colliding with a heavy nucleus, causing it to split.

• Neutrons are responsible for binding protons together in the nucleus.

• Neutrons have no significant role in nuclear reactions.

• Neutrons are emitted as a byproduct of the fission process.

What is nuclear fusion?

• A process where two light atomic nuclei combine to form a heavier nucleus, releasing energy.

• A method of splitting heavy atomic nuclei to release energy.

• A chemical reaction that occurs in stars to produce light.

• A process of combining atoms to create new elements without energy release.

What is the future potential of nuclear fusion as an energy source?

• Nuclear fusion can provide a nearly limitless, clean energy source if technological challenges can be overcome.

• Nuclear fusion is currently the most widely used energy source in the world.

• Nuclear fusion produces more radioactive waste than nuclear fission.

• Nuclear fusion is not a viable energy source due to its high costs.
