How explosion occur?

Answer 1

Explosions occur when a rapid release of energy generates a sudden increase in pressure, often resulting in a shockwave. This can happen through chemical reactions (like combustion), physical changes (such as the rapid expansion of gases), or nuclear reactions. The key factors include the availability of a reactive substance, sufficient energy to initiate the reaction, and the confinement of gases or materials that leads to a buildup of pressure. When the pressure exceeds the surrounding environment, an explosion can occur, resulting in destructive forces.
