Answer
Nuclear fusion
Explanation
Nuclear fusion is the process that powers stars, where light nuclei combine to form heavier nuclei, releasing energy in the process.
Common mistake
Misunderstanding Fusion as Fission
Students often confuse nuclear fusion with nuclear fission, thinking both processes are the same.
To fix this, students should focus on the definitions: 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.
