What is the significance of the red brown smoke that resulted from the Beirut explosion?
The cloud billowing over Beirut is brown and red, the color of nitrogen dioxide released when the ammonium nitrate exploded. A fire breaks out at a port warehouse storing ammonium nitrate.
Why did the Lebanon explosion happen?
The 2020 Beirut explosion occurred on 4 August 2020, when a large amount of ammonium nitrate stored at the Port of Beirut in the capital city of Lebanon exploded, causing at least 218 deaths, 7,000 injuries, and US$15 billion in property damage, and leaving an estimated 300,000 people homeless.
What causes ammonium nitrate explosion?
Ammonium nitrate prills provide a much more concentrated supply of oxygen than the air around us. At high enough temperatures, however, ammonium nitrate can violently decompose on its own. This process creates gases including nitrogen oxides and water vapour. It is this rapid release of gases that causes an explosion.
What are the 4 types of blast injuries?
The four basic mechanisms of blast injury are termed as primary, secondary, tertiary, and quaternary (Table 1).
Why are explosions orange?
The orange/red coloration is caused by the presence of NO2 which is a direct product of the detonation process, and is also produced in the after burning reactions and by the secondary oxidation of NO to NO2 as the cloud mixes with air.
What temperature does ammonium nitrate explode?
Although it starts decomposing at temperatures of about 388 F (170 C), relatively pure ammonium nitrate does not typically explode until temperatures between 500–572 F (260–300 C) or higher are reached.

What is explosion Short answer?
An explosion is a rapid expansion in volume associated with an extremely vigorous outward release of energy, usually with the generation of high temperatures and release of high-pressure gases. Subsonic explosions are created by low explosives through a slower combustion process known as deflagration.
How does an explosion occur?
An explosion occurs when a large amount of energy is released into a small volume of area in a very short time. Burning very rapidly, explosive material releases concentrated gas that expands quickly to fill the surrounding air space and apply pressure to everything in it.
What causes an explosion?
An explosion is a rapid expansion of gases. Many explosions occur when gases are exposed to a source of heat- such as fire, sparks, even static elec- tricity-or an increase in pressure. Explosions can also be caused by chemical reactions. Some chemicals can even explode if exposed to air or water.
What is the shockwave of an explosion?
In fluid dynamics, a blast wave is the increased pressure and flow resulting from the deposition of a large amount of energy in a small, very localised volume. In simpler terms, a blast wave is an area of pressure expanding supersonically outward from an explosive core. …
What type of shock wave is produced when an explosion detonates?
A detonation will also cause a shock of type 1, above to propagate into the surrounding air due to the overpressure induced by the explosion. When a shock wave is created by high explosives such as TNT (which has a detonation velocity of 6,900 m/s), it will always travel at high, supersonic velocity from its point of origin.
What happens when a shock wave reaches an observer?
The edge of the cone forms a supersonic wave front with an unusually large amplitude called a “shock wave”. When a shock wave reaches an observer a “sonic boom” is heard.
Are unsteady shock waves propagated inside channels?
An excellent survey of shock wave phenomena is given by I. I. Glass (1991). From the theoretical point of view shock waves are a good example of a nonlinear wave propagation. The present chapter deals with unsteady shock waves propagating inside channels. As will be shown, the channel geometry has a pronounced effect on the transmitted shock wave.
What causes shock waves to occur in space?
For example, the shock can be propagated by photons interacting with electrons, by a distribution of high energy particles or by magnetic effects. So, shock waves are actually quite common in space. Interplanetary shock waves can occur due to solar flares.
