Why is there a greater risk of explosion with dust in the air than with dust on the ground?
Cause dust can combust real fast and air supports burning the ground doesn't
When viewing film footage of underground nuclear testing the ground surface initially drops appearing to be more of an implosion than an explosion Can anybody please explain this Thank you?
The explosion raises a dust cloud on the surface, that might be what you see early on. Afterwards the ground subsides into the collapsing explosion cavity. But this typically takes minutes, so I don't think thats what you meant.
Is sugar flamamble?
Sugar dust particles will ignite and this will be called the primary explosion, the primary explosion will unsettle more dust and cause a secondary explosion and the second blast will be more powerful. This then can be at threat to other easily combustibles items in the vicinity.
What isNuclear fallout?
Its the nuclear dust and debris that settles in the air after a nuclear explosion. This then comes down on the ground. Its a mixture of nuclear particles, and debris from the surrounding area. This can cause radiation sickness.
What causes a dust explosion?
A dust explosion occurs when a flammable substance in powder form suspended in the air ignites and burns rapidly. When a substance is pulverized, the surface area that is directly exposed to the air increases dramatically. This large surface area allows the combustion reaction to occur much more rapdily than would normally be possible, causing an explosion. Substances that can produce dust explosions include sawdust, grain dust, coal dust, starch, flour, and even some metals.
Why do extractor fans reduce the possibility of an explosion in a flour mill?
Extractor fans help to remove dust and flour particles from the air, reducing the concentration of potentially combustible particles in the air. By reducing the amount of flour dust in the air, the risk of an explosion in a flour mill is decreased because there are fewer combustible materials available to ignite.
Is dust explosion is possible in wheat flour dust?
Many solids like wheat dust, wood dust and even metals in their dust form have high surface area. With a high surface area and surrounded by oxygen (as in the air), combustion can take place at a very rapid rate. This rapid rate of combustion can lead to an explosion. In fact, Dust explosions are hazards in many industries. Taffy
Why does the sky turn black after a nuclear explosion?
It might be because of dust in the atmosphere elevated by the explosion. Particles of dust absorb and scatter visible light very well. And the sky turn to black because there is on light coming through dust clouds.
What is galaxies formation?
Galaxies formed from dust, matter, and energy that formed from the explosion of the universe.
What is the first step in building a solar system from solar nebula?
an explosion disturbs the dust in the nebula
What is the name of radioactive dust after nuclear explosion?
The radioactive dust that forms after a nuclear explosion is called "fallout." It consists of particles that have been contaminated by radioactive material and can be carried by wind over long distances, posing a health risk to humans and the environment.
Why is an explosion is more likely to occur with coal dust than with lumps of coal?
Coal dust particles have a larger surface area compared to lumps of coal, allowing for faster combustion and easier ignition. The dispersed nature of dust particles also creates more opportunities for them to come into contact with an ignition source, increasing the likelihood of an explosion.
