Term
Definition: Boiling Point
Definition
Temperature at which a LIQUID changes to a GAS. The closer to the boiling point, the most vapors that are produced.
Term
Definition: Fire Point
Definition
The lowest temperature at which a LIQUID with an outside source of ignition sustains burning.
Term
Definition: Flash point
Definition
The minimum temperature of a LIQUID that produces enough vapors to form an ignitable mixture with air when an ignition source is present
Term
Definition: Volitility
Definition
Is the relative quantity of vapors that come from the material versus a specific standard at a specific temperature. IN OTHER WORDS: The relative quantity of vapors that come from a material.
Term
Definition: Relative response
Definition
Term used to describe the way a monitor reacts to a gas other than its calibration gas.
Term
Polar Solvents are?
Definition
Solvent in water
Term
Definition: Deposition
Definition
What a gas forms a solid...RARE. Found in nuclear explosions.
Term
Definition: Pyrophoric
Definition
When a material is reactive with air or water
Term
Definition: Polymerization
Definition
When small compounds called monomers react with themselves and become polymers.
Term
Definition: Carboy
Definition
A glass or plastic bottle used to store or transport corrosive liquids. Can be as large as 20 gallons, but common is 5 gallons.
Term
Definition: Jerrican
Definition
Rectangular plastic carboys. Typically used to transport flammable and combustible liquids.
Term
Definition: Cylinder
Definition
Pressure vessel designed for higher than 40 psi
Term
Definition: Dust
Definition
Solid particle that is formed or generated from solid organic or inorganic materials.
Term
Definition: Fume
Definition
Suspension of particles that form when a material from a volatilized solid condenses in cool air
Term
Definition: Mist
Definition
Finely divided liquid suspension in the atmosphere
Term
Definition: Aersol
Definition
Form of mist characterized by highly respirable, minute liquid particles
Term
Definition: Fiber
Definition
Solid particles whose length is several times greater than its diameter
Term
Definition: Vapor
Definition
Gaseous form of a substance that is normally in a solid or liquid state at room temperature and pressure.
Term

Definition
Weight of a given volume of pure vapor or gas. >1 is heavier than air, <1 is lighter than air. The majority of gases are >1
Term
Definition: Miscibility
Definition
Degree or readiness to which two or more gases or liquids are able to mix with or dissolve into each other.
Term
Definition: Specific Gravity
Definition
Ratio of the density of a material to the density of a standard materials at standard conditions or pressure and temp. >1 will sink, <1 will float.
Term
Definition: Reactivity
Definition
Its relative ability to undergo a chemical reaction with another material
Term
Definition: Inhibitor
Definition
Added to products that easily polymerize in order to control or prevent an undesired reaction.
Term
Definition: Ionization
Definition
Process of removing electrons from atoms and also the method by which radiation causes damage to human body.
