Nuclear fission and fusion

Question

A. Maintaining low temperatures.
B. Creating a vacuum environment.
C. Overcoming electrostatic repulsion between nuclei.
D. Using heavy nuclei.

Answer

The correct answer is C: Overcoming electrostatic repulsion between nuclei..

Explanation

The correct answer is C: Overcoming electrostatic repulsion between nuclei.. This supports the learning objective "(Physics only) Explain why fusion is difficult to use as an energy source on Earth." 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: Maintaining low temperatures.; Creating a vacuum environment.; Using heavy nuclei..

Common mistake

Misunderstanding Fusion Conditions

Students often think that fusion can occur at normal temperatures and pressures, not realizing the extreme conditions required.

Emphasize that fusion requires very high temperatures and pressures to overcome electrostatic repulsion between nuclei.
