| Consider the following statements. |
| 1. The hydrogen bomb is based on thermonuclear fission reaction. |
| 2. The fundamental physics of the fission chain reaction in a nuclear weapon is quite different to the physics of a controlled nuclear reactor. Also, the two types of devices are engineered differently. |
| 3. No industrialised nation has been able to meet even one-fourth of its total demand of energy from nuclear reactors. |
| Which of the statements] given above is/are correct? |
A) 1 and 2
B) Only 3
C) All of these
D) None of these
Correct Answer: D
Solution :
[d] The hydrogen bomb is based on thermonuclear fusion reaction. A nuclear bomb based on the fission of uranium or plutonium is placed at the core of the hydrogen bomb. This nuclear bomb is embedded in a substance which contains deuterium and lithium. When the nuclear bomb (based on fission) is detonated, the temperature of this substance is raised to 10'K in a few microseconds. The high temperature generates sufficient energy for the light nuclei to fuse and a devastating amount of energy is released.
