What pressure for a chemical or solution is considered an explosive hazard?
when the vapor pressure is greater than 5 mm
What type of material do explosive volcanoes produce?
An explosive eruption is caused by magma with a high content of water and silica. Non-explosive eruptions are caused by either lava because it is a thicker consistency, or magma with a low content of water and silica.
Is refrigerant leaving a compressor in a cars air conditioning system high pressure vapor high pressure liquid or low pressure vapor?
high pressure vapor
What happens to vapor pressure if sugar is added to a solution?
When you add a teaspoon of honey to water with vapor pressure, it will reduce the vapor pressure. The sugar in the honey leads to the pressure going down.
What determines whether a volcano will erupt violently or quietly?
if a volcano is high in silica, it will be explosive. If its low in silica, it will be quiet. Two important things that determine whether an eruption will be explosive or quiet: # The amount of water vapor and other gases that are trapped in the magma. # If the magma is basaltic or grantic.

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 are the six physical properties associated with hazard recognition of hazardous materials chemicals?
vapor pressure evaporation rate flashpoint upper explosive limit lower explosive limit
What are the six physical properties associated with hazard recognition of hazardous materials and chemicals?

Who invented the explosive vapor detector?
Lorne Elias invented the explosive dectorin 1985 Lorne Elias invented the explosive dectorin 1985
Does water vapor affect how explosive a volcano is?
Yes. More gas trapped in magma leads to a more explosive eruption. Water vapor is the most abundant gas in magma.
What has to happen for a gas or vapor to be flammable or an explosion hazard?
For a gas or vapor to be flammable or an explosion hazard it must have a concentration in air between the Lower Explosive Limit (LEL) and the Upper Explosive Limit (UEL) for that particular gas or vapor.
What does the vapor pressure of water at 10 C compare with its vapor pressure at 50 C?
At higher temperature the vapor pressure is higher.
What type of material do explosive volcanoes produce?
An explosive eruption is caused by magma with a high content of water and silica. Non-explosive eruptions are caused by either lava because it is a thicker consistency, or magma with a low content of water and silica.
What will a hydrate do if its vapor pressure is higher than the vapor pressure of the water vapor in the air?
