(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 0f hydrogen.
(b) The hydrogen bomb consists of heavy isotopes of hydrogen (deuterium and tritium) along with lithium-6. The explosion of hydrogen bomb is done by using an atom bomb. When the atom bomb is exploded, its fission reaction produces a lot of heat which raises the temperature of deuterium and tritium to 107°C in a few microseconds. Then fusion reactions of deuterium and tritium take place producing a tremendous amount of energy. This explodes the hydrogen bomb. Lithium-6 is used to produce more tritium needed for fusion.
(c) The source of energy is same for both the sun and the hydrogen atom, i.e. nuclear fusion.
