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?
The material has malleability, the ability to be shaped or extended by physical pressure without breaking or cracking.
Why can lava be explosive or non explosive?
Lava can be explosive if it is high in gas content, such as dissolved water vapor or carbon dioxide, which can cause pressure to build up and lead to explosive eruptions. On the other hand, lava can be non-explosive if it is low in gas content and flows more easily without building up pressure, resulting in effusive eruptions with slower lava flows.
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 pressure for a chemical or solution is considered an explosive hazard?
when the vapor pressure is greater than 5 mm
What is the vapor pressure considered a chemical or solution considered an explosive hazard?
When the vapor pressure of a chemical or solution exceeds atmospheric pressure, it can pose an explosive hazard. This is because high vapor pressure indicates that the substance can easily evaporate and form a flammable or explosive atmosphere when mixed with air in certain concentrations. Proper handling and storage procedures are necessary to mitigate this risk.
What energy is in a firecraker?
A firecracker contains chemical energy stored in its gunpowder or explosive material. When ignited, the chemical reactions release this energy in the form of heat, light, sound, and pressure.
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.
What type of energy does a firecracker use?
A firecracker uses chemical energy stored in the explosive material inside it. When ignited, this chemical energy is rapidly released as heat, light, sound, and pressure, causing the firecracker to explode.
Is something that is explosive a physical or chemical property?
Explosiveness is a chemical property because it involves the chemical reaction that results in a rapid release of gas, heat, and pressure. It is not an inherent physical property of the material itself.
What energy transformation occurs in a firecracker?
In a firecracker, chemical energy stored in the explosive material is rapidly converted into thermal (heat) and light energy, leading to the explosion and generation of heat and light.
Is pressure a physical change or chemical change?
Pressure is a physical property that can change based on the conditions of a substance, such as temperature and volume. It does not involve a change in the chemical composition of a substance, so it is not considered a chemical change.
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.
Why do explosives explode?
Explosives explode due to a rapid release of stored energy, often in the form of heat, light, sound, and pressure. This release of energy occurs when the chemical bonds within the explosive material are broken, causing the material to rapidly expand and generate a shock wave.
