Question

Hydrogen bomb is based upon :

• A. fission
• B. fusion
• C. chemical reaction
• D. transmutation

Answer 1

Answer: (B)

The working of hydrogen bomb is based on nuclear fusion.
But for the process of nuclear fusion, a very high temperature $(\approx 10^7)$ and a very high pressure is required,
hence to construct a hydrogen bomb, first atom bomb is constructed.
The atom bomb is then covered from all sides by an enclosure of a compound of heavy hydrogen (deuteron) such as lithium hydride.
First the atom bomb is exploded which produces such a high temperature and pressure that deuteron nuclei get fused and a huge amount of energy is released.
