What occurs when the pressure of an explosion expanded and tears the casing of the explosive?
When the pressure of an explosion expands and tears the casing of the explosive, it results in the release of the explosive material and the creation of a shockwave. This can lead to widespread damage and destruction in the surrounding area, depending on the size and strength of the explosion.
What pressure for a chemical or solution is considered an explosive hazard?
when the vapor pressure is greater than 5 mm
Is a volcanic explosion a chemical reaction?
Explosions may or may not represent a chemical change. A stick of TNT going off is a chemical explosion. A compressed gas cylinder with a failing weld that blows up while being filled is a mechanical explosion. In the case of a volcano, the cause of the explosion is mechanical. We take a page from physics to answer this question. It is a buildup of pressure caused by heating of the magma (which may include gases and water) that causes the violent release of energy that we observe.
If a material can be shaped or extended by physical pressure which property does the material have?
A substance is considered to be ductile, if it can be hammered out thin or drawn into a wire.
What gives a firework its explosion?
It depends on the explosion. Chemical ones need heat, or shock (like nitroglycerine) or a small blast to "set off" a charge (like the detonator in a 500 pound bomb). As far as a mechanical one, a mechanical trigger like a pin in a balloon or too much pressure in a compressed gas cylinder and the mechanical failure of the container due to overpressure will do the trick. In a fission nuclear weapon, forcing enough fissile material together with a chemical explosive and holding it together a split second to permit the chain reaction to build sufficiently will set it off. For a fusion weapon, a fission weapon will be needed to create the heat and pressure around the fusion material to cause it to fuse and go off.
What is the vapor pressure on the Material Safety Data Sheet for a chemical or solution that is considered an explosive hazard?
The pressure is greater then 10 mm.
How is evaporation considered to be a physical change and not a chemical change?
There is no electron rearrangement when a material evaporates, which is what defines a chemical change. Evaporation is the material's vapor pressure overcoming the particular force (Van der Waals, etc) that otherwise keeps it a liquid.

Is pressure a physical change or chemical change?
A physical change. The chemical make up of the material is not changed. --------------------------------------------------------------------- Pressure is not a change, it is a characteristic. It is the ratio force/area.
Is exploding a chemical change?
An explosion is the sudden release of a volume of compressed gas. The chemicals remain the same, so it is only a physical change.Note that the reaction resulting in an explosion may be a chemical change, but the resulting pressure changes are not.

Fragmentation
Why is explosion in a coal mine a physical change?
I would tend to believe that the pressure wave from the explosion exerts tremendous force against the surrounding chambers and tunnels. Physically stressing and fracturing the rock or substrate material. without physical bonding of the minerals in the substrate they lose their structural integrity. compromising the material .
