Nuclear fission and fusion
Question
- A. It increases the temperature of the nuclei
- B. It forces the nuclei closer together to collide
- C. It stabilizes the resulting nucleus
- D. It reduces the energy required for fusion
Answer
The correct answer is B: It forces the nuclei closer together to collide.
Explanation
The correct answer is B: It forces the nuclei closer together to collide. This supports the learning objective "(Physics only) Explain why fusion requires very high temperatures." in Nuclear fusion (physics only) because it uses the correct atomic and nuclear radiation relationship for Nuclear fission and fusion. The other options are less suitable because they do not match the required Nuclear fusion (physics only) idea: It increases the temperature of the nuclei; It stabilizes the resulting nucleus; It reduces the energy required for fusion.
Common mistake
Misunderstanding Fusion Temperature Requirements
Students often think that fusion can occur at normal temperatures without understanding the need for extremely high temperatures to overcome electrostatic repulsion between positively charged nuclei.
Emphasize that fusion requires very high temperatures, typically in the millions of degrees, to provide the necessary energy for nuclei to collide and fuse.
