What pressure for a chemical or solution is considered an explosive hazard?
when the vapor pressure is greater than 5 mm
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 occurs when the pressure of an explosive expands and tears the casing of the explosive?
Fragmentation
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.
How do adhesives work?
Some adhesives soak into the material then dry out. Others are pressure sensitive, and others have a chemical reaction.
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.
What is the vapor pressure considered a chemical or solution considered an explosive hazard?
ho2
What pressure for a chemical or solution is considered an explosive hazard?
when the vapor pressure is greater than 5 mm
Is volcanic ash explosive?
No- but it may explode from a volcano due to the pressure behind it. The material itself is not an explosive.
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.
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.
Yellow x with 2 is what hazard?
If an NFPA 704 Fire Diamond has a 2 in the yellow section it means the reactivity of the material is such that it can have violent chemical change at high temperature or pressure, it can react violently with water, or it can form explosive mixtures with water.
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.
How do you make plastic explosives?
A typical explosive consists of some explosive material, some sort of detonation device and, typically, some sort of housing. The explosive material undergoes a rapid chemical reaction, either a combustion or decomposition reaction, when triggered by heat or shock energy from the detonator.In the chemical reaction, compounds break down to form various gases. The reactants (the original chemical compounds) have a lot of energy stored up as chemical bonds between different atoms. When the compound molecules break apart, the products(the resulting gases) may use some of this energy to form new bonds, but not all of it. Most of the "leftover" energy takes the form of extreme heat.The concentrated gases are under very high pressure, so they expand rapidly. The heat speeds up the individual gas particles, boosting the pressure even higher. In a high explosive, the gas pressure is strong enough to destroy structures and injure and kill people. If the gas expands faster than the speed of sound, it generates a powerful shock wave. The pressure can also push pieces of solid material outward at great speed, causing them to hit people or structures with a lot of force.

Fragmentation
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.
In what section of the MSDS would you find the vapor pressure density of a material?
The vapor pressure and density of a given material is found in the physical section of the MSDS. Density is calculated by dividing mass by volume.
