WebDefinition of Nuclear Fusion. Nuclear fusion is a reaction in which two or more atomic nuclei join together to form a single, heavier nucleus. This reaction releases a tremendous amount of energy, and is the same process that powers stars, such as our sun and other stars in the universe. Nuclear fusion is different from nuclear fission, which ... WebOct 7, 2003 · 0. A protostar will begin gravitational collapse only if the total gravitational potential energy exceeds twice the thermal energy. In other words, a gas has to be sufficiently cool and sufficiently dense to collapse. Also, as the protostar collapses about half of the gravitational PE is converted into heat, and about half is radiated into space.
WebThe proton–proton chain, also commonly referred to as the p–p chain, is one of two known sets of nuclear fusion reactions by which stars convert hydrogen to helium.It dominates in stars with masses less than or equal to that of the Sun, whereas the CNO cycle, the other known reaction, is suggested by theoretical models to dominate in stars with masses … WebSep 29, 2015 · 1 Answer.
