What is nuclear fusion?

• Nuclear fusion is a process in which two light atomic nuclei split apart, releasing a large amount of energy.

• Nuclear fusion is a process in which two heavy atomic nuclei combine to form a lighter nucleus, releasing a large amount of energy.

• Nuclear fusion is a process in which two light atomic nuclei combine to form a heavier nucleus, absorbing a large amount of energy.

• Nuclear fusion is a process in which two light atomic nuclei combine to form a heavier nucleus, releasing a large amount of energy.

Explain the process of nuclear fusion.

• Nuclear fusion is the process where atoms split apart to release energy.

• Nuclear fusion is the process where atoms remain stable without any energy release.

• Nuclear fusion is the process where two heavy atomic nuclei combine to form a lighter nucleus.

• Nuclear fusion is the process where two light atomic nuclei combine to form a heavier nucleus, releasing a large amount of energy.

What are the potential benefits of nuclear fusion?

• Abundant clean energy, minimal radioactive waste, utilization of widely available fuel sources

• High cost of implementation

• Unlimited greenhouse gas emissions

• Limited availability of fuel sources

Define nuclear fission.

• The emission of radiation from an atomic nucleus.

• The process of converting nuclear energy into electrical energy.

• The combination of atomic nuclei to form a larger nucleus.

• The splitting of an atomic nucleus into smaller nuclei.

How does nuclear fission differ from nuclear fusion?

• Nuclear fission releases energy, while nuclear fusion absorbs energy.

• Nuclear fission splits heavy nuclei, while nuclear fusion combines light nuclei.

• Nuclear fission combines light nuclei, while nuclear fusion splits heavy nuclei.

• Nuclear fission occurs naturally, while nuclear fusion requires human intervention.

What are the main products of nuclear fission?

• heat, light, sound

• helium, carbon, oxygen

• protons, electrons, gamma rays

• energy, neutrons, radioactive fission products

Discuss the concept of chain reaction in nuclear fission.

• A chain reaction in nuclear fission is the process where one neutron colliding with a fissile atom causes it to split and release more neutrons, which in turn can collide with other fissile atoms, leading to a self-sustaining reaction.

• A chain reaction in nuclear fission is a slow process that requires external stimuli to continue.

• A chain reaction in nuclear fission involves the fusion of atoms rather than their fission.

• A chain reaction in nuclear fission always leads to a complete shutdown of the reaction after a few iterations.

What are the risks associated with nuclear fission?

• Minimal environmental impact

• Radioactive waste disposal, accidents, proliferation of nuclear weapons, high costs

• Low energy output

• Nuclear fusion risks

Compare and contrast nuclear fusion and nuclear fission.

• Nuclear fusion releases more energy than nuclear fission.

• Nuclear fusion combines light nuclei, while nuclear fission splits heavy nuclei.

• Nuclear fusion splits heavy nuclei.

• Nuclear fission combines light nuclei.

Explain how nuclear energy is harnessed in power plants.

• Nuclear energy is harnessed in power plants by wind turbines.

• Nuclear energy is harnessed in power plants by burning coal.

• Nuclear energy is harnessed in power plants through solar panels.

• Nuclear energy is harnessed in power plants through nuclear fission, where uranium atoms are split to release heat that generates steam to drive turbines and produce electricity.
