Question

7. What is an explosion?​

Answer 1

Answer:

An explosion is a rapid increase in volume and release of energy in an extreme manner, usually with the generation of high temperatures and the release of gases. Supersonic explosions created by high explosives are known as detonations and travel via supersonic shock waves. Subsonic explosions are created by low explosives through a slower burning process known as deflagration.

• A very fast combustion reaction in which a large amount of heat, light and sound are produced is called explosive combustion.
• A large amount of gases is released quickly.It is the rapid expansion of these gases which causes a loud sound.
