Write the principle of working of hydrogen bomb. How is hydrogen bomb accomplished?
Working of hydrogen bomb:
When two light nuclei like hydrogen or it's isotopes combine to form a heavy nucleus undergoing the process of fusion, a tremendous amount of energy is released. Hydrogen bomb is based on thermonuclear fusion reaction.
The reaction is as follows:
2H + 2H → 3He + n + energy
Degree of temperature and pressure required for the process is really high. The conditions are different.
An atomic bomb based on fission of uranium or plutonium is placed at the core of the hydrogen bomb. When atomic bomb is detonated, the temperature of the substance is raised to 107 K in micro seconds. The high temperature gives sufficient energy for the hydrogen nuclei to fuse and release enormous amount of energy which causes destruction.
Which of the following phenomena may help in the making of more destructive weapon?
(i) Nuclear fission (ii) Nuclear fusion.
Name the weapon.
