Understanding Nuclear Fusion

What is the primary cause of the energy crisis?

• Decrease in global energy demand

• Lack of technological advancements

• Dependence on finite fossil fuels

• Overuse of renewable resources

What process powers the sun and stars?

• Electromagnetic radiation

• Nuclear fusion

• Nuclear fission

• Chemical combustion

How does nuclear fusion differ from nuclear fission?

• Fusion produces less energy than fission

• Fusion combines light nuclei, fission splits a heavy nucleus

• Fusion occurs naturally on Earth

• Fusion splits a heavy nucleus, fission combines light nuclei

What are the conditions required for nuclear fusion on Earth?

• Low temperature and low pressure

• Low temperature and high pressure

• High temperature and high pressure

• High temperature and low pressure

What makes nuclear fusion a potentially limitless energy source?

• It harnesses wind power

• It uses uranium, which is plentiful

• It relies on solar energy

• It uses water and lithium, which are abundant

Why is nuclear fusion considered environmentally friendly?

• It emits carbon dioxide

• It produces no waste

• It has minimal environmental impact

• It produces long-lived radioactive waste

What is a major safety advantage of nuclear fusion over fission?

• Can be easily controlled

• Produces less radioactive waste

• No risk of a chain reaction leading to a meltdown

• Uses less fuel

What is a significant challenge in harnessing nuclear fusion?

• Achieving and maintaining the necessary low temperatures

• Ensuring the safety of the process

• Finding sufficient quantities of fuel

• Achieving and maintaining the necessary high temperatures and pressures

What is the role of advanced materials in nuclear fusion research?

• To generate the fusion reaction

• To contain and control the fusion reaction

• To cool down the reactors

• To serve as fuel for the fusion reaction

Why is nuclear fusion not yet a widespread source of energy?

• It is too expensive

• The technology is not yet fully developed

• It is not safe

• It has a large environmental impact
