Question

Hydrogen bomb is based on the principle of
A. Nuclear fission
B. Nuclear fusion
C. Nuclear explosion
D. Chemical reaction

Answer 1

Hint: To answer this question, we first need to understand what bombs are. A bomb is an explosive device that releases energy in an exceedingly rapid and violent manner by using the exothermic reaction of an explosive substance. Detonations cause damage primarily by mechanical stress communicated through the ground and environment, projectile impact and penetration, pressure damage, and explosion-generated effects.

Complete step-by-step solution:
Hydrogen bomb - A thermonuclear weapon, often known as a fusion weapon or hydrogen bomb (H bomb), is a type of nuclear weapon developed in the second generation. Its sophistication allows it to have far more destructive power than first-generation atomic bombs, as well as a smaller size, reduced mass, or a combination of these advantages.
Because of the characteristics of nuclear fusion processes, non-fissile depleted uranium can be used as the weapon's principal fuel, allowing for more efficient use of limited fissile materials like uranium.
Current fusion weapons have two main components: a nuclear fission primary stage and a separate nuclear fusion secondary stage that uses thermonuclear fuel such as the heavy hydrogen isotopes deuterium and tritium, or lithium deuteride in modern weapons. As a result, thermonuclear weapons are commonly referred to as hydrogen bombs or H-bombs.
So, we conclude that, Hydrogen bomb is based on the principle of nuclear fusion.
So, the final answer is option (B) i.e., nuclear fusion

Note:Nuclear fusion occurs when two or more atomic nuclei unite to generate one or more new atomic nuclei and subatomic particles. The release or absorption of energy is caused by the mass differential between the reactants and products.
