Nuclear Explosion Essay

An explosion is defined as a large-scale, rapid and sudden release of energy. The exact source of this energy is relatively in material; it may come from an explosive such as gunpowder, from pressurized steam in boiler, or from uncontrolled nuclear transformation. [4] Explosion can be classified on the basis their nature, their physical state and rate of decompositions.
(a) According to their nature:
In physical explosion:-
Energy may be released from the catastrophic failure of a cylinder of a compressed gas, volcanic eruption or even mixing of two liquid at different temperature.
In nuclear explosion:-
Energy is released from the formation of different atomic nuclei by the redistribution of the protons and neutrons within the inner acting

For instance, the explosives used in the 1995 Murrah Federal Building bombing in Oklahoma and the 1992 World Trade Center Building bombing in New York were of the third category, i.e., fertilizer-type (Ammonium Nitrate Fuel Oil explosive) [22]
(b) According to physical state:
According to physical state they can be classified as solids, liquids & gases. [22]
(c) According to rate of decomposition:
Explosives are classified as low and high depending on the amount of energy released by them and the consequent damage caused by them (Figure A.1). [2]
Low Explosives:-
They only burn, but do not detonate. They are set-off to deflagrate, rather than to detonate. An example of the low explosive is the black powder.
High Explosive:-
They are designed to shatter, rather than to push. Examples of the high explosives are Dynamite and TNT.
High explosives detonate to create shock waves, burst or shatter materials in or which they are located, penetrated materials, produce lift and heave of materials and, when detonated in air or under water, produce air blast or underwater pressure pulses. [10]
