Answer 1

EXPLANATION:
Hydrogen Bomb

It contains a mixture of deuterium oxide and tritium oxide in a space surrounding an ordinary hydrogen bomb.
The first step of the reaction is endothermic i.e. reaction between deuterium oxide and tritium oxide is initiated by the energy obtained from the explosion of the atom bomb.
The second step of the reaction is exothermic i.e. energy evolving.
Nuclear Fusion
The process which involves the fusion of two or lighter nuclei to give heavier nuclei is called nuclear fusion.
It occurs only at extremely high temperatures (>10⁶K), so also called thermonuclear reactions.
It is used in a hydrogen bomb.
The energy of the sun and stars is also a result of a series of nuclear fusion reactions.

Additional Information

Nuclear Fission

It is the phenomenon of artificial transmutation in which a heavy nucleus splits up into two or lighter nuclei of nearly comparable mass with the release of a tremendous amount of energy.
It was discovered by two German scientists Otto Hahn and Fritz Strassmann in 1939.
