Explosions are just a chemical reaction. When the chemicals in the explosive react they create large volumes of gases. These gases have to go somewhere so they push outwards destroying or moving anything in their way. For example in trinitrotoluene (or as it is more commonly known as TNT) which is one of the most commonly known explosives. The damage it causes is by 15 moles of gas pressing out from the space which was once occupied by 2 moles of TNT. 1 mole is about 18 grams so for a gas which weigh’s next to nothing tats a lot for though who don’t know that. Basically the gas is going to push outwards until it is taking up an amount of space it’s happy with. And since the gas is relisted at such a high rate you have the damage caused by the impact as well as the pressure. So if you put explosives in an enclosed space it will find a way out.
These properties of explosives make them very useful for many purposes some of which I will cover in my next post.
