Explosions

Explosions all take part of thermodynamics. Thermodynamics deals with heat and it's relation to other types of energy. Thermodynamics also deals with endo- and exothermic reactions, and enthalpy. Endothermic reactions is when heat is absorbed by a system from its surroundings. Exothermic reactions is when heat is released by a system to its surroundings. Enthalpy is a measure of total energy of a system. Enthalpy includes energy to create a system, and the energy needed to be displaced into the surroundings in order to establish its volume and pressure. An explosion is a detonation rather than a burn. In a detonation, a chemical reaction occurs which releases gases that rapidly expand and give off energy, which would be determined as exothermic reaction. There are two types of explosions; low and high explosives. Low explosives create low pressure and burn a slow rates, and mostly used to force a bullet out of a gun or send rockets to space. High explosives create more pressure and burn quickly, and creates minimal ground vibrations. High explosives are mainly used by explosive engineers. Explosive engineers are responsible for breaking up rocks to make way for houses, buildings, roads, and bridges. Explosions are also used in many more careers such as; agriculture, diamond manufacturing, logging, medical field, many more.
