Term | Definition |
Definition: Boiling Point | Temperature at which a LIQUID changes to a GAS. The closer to the boiling point, the most vapors that are produced. |
Definition: Fire Point | The lowest temperature at which a LIQUID with an outside source of ignition sustains burning. |
Definition: Flash point | The minimum temperature of a LIQUID that produces enough vapors to form an ignitable mixture with air when an ignition source is present |
Definition: Volitility | 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. |
Definition: Relative response | Term used to describe the way a monitor reacts to a gas other than its calibration gas. |
Polar Solvents are? | Solvent in water |
Definition: Deposition | What a gas forms a solid...RARE. Found in nuclear explosions. |
Definition: Pyrophoric | When a material is spontaneously reactive with air or water. Usually below 130 degrees F. |
Definition: Polymerization | When small compounds called monomers react with themselves and become polymers. |
Definition: Carboy | A glass or plastic bottle used to store or transport corrosive liquids. Can be as large as 20 gallons, but common is 5 gallons. |
Definition: Jerrican | Rectangular plastic carboys. Typically used to transport flammable and combustible liquids. |
Definition: Cylinder | Pressure vessel designed for higher than 40 psi |
Definition: Dust | Solid particle that is formed or generated from solid organic or inorganic materials. |
Definition: Fume | Suspension of particles that form when a material from a volatilized solid condenses in cool air |
Definition: Mist | Finely divided liquid suspension in the atmosphere |
Definition: Aersol | Form of mist characterized by highly respirable, minute liquid particles |
Definition: Fiber | Solid particles whose length is several times greater than its diameter |
Definition: Vapor | Gaseous form of a substance that is normally in a solid or liquid state at room temperature and pressure. |
Definition: Vapor density | 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 |
Definition: Miscibility | Degree or readiness to which two or more gases or liquids are able to mix with or dissolve into each other. |
Definition: Specific Gravity | 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. |
Definition: Reactivity | Its relative ability to undergo a chemical reaction with another material |
Definition: Inhibitor | Added to products that easily polymerize in order to control or prevent an undesired reaction. |
Definition: Ionization | Process of removing electrons from atoms and also the method by which radiation causes damage to human body. |
Definition: Melting point | Temperature at which a solid becomes a liquid. This temperature is the same as when it goes from liquid to solid again. |
Definition: suspension | A chemical that has not dissolved in a liquid |
Definition: Viscosity | The resistance of a liquid to flow |
What is the difference between boiling and evaporation? | Evaporation is a surface phenomenon. Boiling is a bulk process. |
Definition: Condensation | Change of a gas to a liquid |
