Nuclear Fission and Fusion: Release of Energy from Atomic Nuclei

The video tutorial explains nuclear fission and fusion processes. It begins with nuclear fission, describing how a large unstable nucleus like uranium 235 splits into smaller nuclei, releasing energy. The concept of chain reactions in fission is discussed, highlighting controlled reactions in reactors and uncontrolled ones in explosions. The tutorial then shifts to nuclear fusion, where light nuclei combine to form a heavier nucleus, releasing energy. The extreme conditions required for fusion, such as high pressure and temperature, are outlined, noting that fusion occurs naturally in stars but is challenging to achieve safely on Earth.
