Nuclear fission and fusion

Question

A. It requires low temperatures to occur
B. It releases energy
C. It is the process of splitting large nuclei
D. It does not occur in stars

Answer

The correct answer is B: It releases energy.

Explanation

The correct answer is B: It releases energy. This supports the learning objective "(Physics only) State that nuclear fusion releases energy." 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 requires low temperatures to occur; It is the process of splitting large nuclei; It does not occur in stars.

Common mistake

Confusing Fusion with Fission

Students often confuse nuclear fusion with nuclear fission, thinking both processes are the same.

Remember that nuclear fusion is the joining of two light nuclei to form a heavier nucleus, while nuclear fission is the splitting of a large unstable nucleus.
