Question

Quizplus · Accepted Answer

Fusion reactions differ from fission in that they do not require a critical mass to sustain the reaction. Fusion involves combining light nuclei, such as hydrogen isotopes, to form heavier nuclei, releasing energy in the process. This is fundamentally different from fission, which involves splitting heavy nuclei like uranium. The critical mass requirement is a characteristic of fission reactions, where a certain amount of fissile material is needed to maintain a chain reaction. Fusion, on the other hand, primarily depends on extremely high temperatures and pressures to overcome the electrostatic repulsion between nuclei, rather than a critical mass of material.
