1. What is the primary process that powers the Sun and other stars?
Nuclear fission
Nuclear fusion
Chemical reactions
Radioactive decay
2. Which of the following is a key characteristic of nuclear fission?
Two light nuclei combine to form a heavier nucleus.
A heavy nucleus splits into two or more lighter nuclei.
Electrons are transferred between atoms.
Protons and neutrons are exchanged between nuclei.
3. Nuclear fission releases a tremendous amount of in the form of heat and radiation.
4. The process of nuclear fusion requires extremely high temperatures and to overcome the electrostatic repulsion between nuclei.
5. In a nuclear power plant, a controlled reaction of uranium-235 is used to generate electricity.
6. Briefly explain the main difference between nuclear fission and nuclear fusion.
7. Describe one potential advantage and one potential disadvantage of using nuclear fusion as an energy source compared to nuclear fission.
