(a) What is the source of energy of the sun and other stars?(b) Describe the working of a hydrogen bomb.
(c) What is common between the sun and a hydrogen bomb?
(a) Nuclear fusion reactions of hydrogen are the source of energy of the sun and other stars.
(b) We know that a hydrogen bomb consists of heavy isotopes of hydrogen (deuterium, tritium) along with lithium. The explosion of a hydrogen bomb is done by using an atom bomb. When an atom bomb is exploded, it produces a lot of heat, which raises the temperature of deuterium and tritium to an extent in a few microseconds. At this temperature, fusion reactions of deuterium and tritium take place, producing a tremendous amount of energy. This process causes the explosion of a hydrogen bomb.
(c) In the sun as well as in a hydrogen bomb, the source of energy is the same that is the nuclear fusion reaction of hydrogen.
