GENERAL KNOWLEDGE

Detailed explanation-1: -Fusion reactions take place in a state of matter called plasma-a hot, charged gas made of positive ions and free-moving electrons with unique properties distinct from solids, liquids or gases. The sun, along with all other stars, is powered by this reaction.

Detailed explanation-2: -Fusion reaction begins in the protostar stage of the star.

Detailed explanation-3: -The temperature must be hot enough to allow the ions of deuterium and tritium to have enough kinetic energy to overcome the Coulomb barrier and fuse together. The ions must be confined with a high ion density to achieve a suitable fusion reaction rate.

Detailed explanation-4: -The power that fuels the sun and the stars is nuclear fusion. In a hydrogen bomb, two isotopes of hydrogen, deuterium and tritium are fused to form a nucleus of helium and a neutron. This fusion releases 17.6 MeV of energy.
