Questions and Answers
Adsorption - ✅✅the collection of one substance on the surface of another
Absorption - ✅✅the process or action by which one thing absorbs or is
absorbed by another.
Alkali - ✅✅a chemical compound that neutralizes or effervesces with acids and
turns litmus blue; typically, a caustic or corrosive substance of this kind such as
lime or soda.
CAS Number - ✅✅Number assigned by the American Chemical Society's
Chemical Abstract Service that uniquely identifies a specific compound.
Corrosive - ✅✅having the tendency to erode or eat away (The effect of the
chemical was highly corrosive.)
Flash point - ✅✅Minimum temperature at which a liquid gives off enough
vapors to form an ignitable mixture with air near the liquid's surface.
Flame point - ✅✅The lowest temperature at which a liquid produces enough
vapor to sustain a continuous fire.
Ignition temp - ✅✅the minimum temperature at which fuel vapor will ignite
, Miscibility - ✅✅The degree to which two liquids can mix.
MSST - ✅✅maximum safe storage temperature
Oxidizer - ✅✅Any material that readily yields oxygen or other oxidizing gas, or
that readily reacts to promote or initiate combustion of combustible materials.
Pressure relief device - ✅✅A device actuated by inlet pressure and designed to
open during an emergency or abnormal condition to prevent a rise of internal
pressure in excess of a specified value.
SADT - ✅✅Self Accelerating Decomposition Temperature - lowest temperature
at which an organic peroxide in a typical vessel or shipping package will undergo a
self-accelerating decomposition within one week
Sublimation - ✅✅A change directly from the solid to the gaseous state without
becoming liquid
Vapor Density - ✅✅weight of a vapor compared to air
Viscosity - ✅✅a liquid's resistance to flow
Volatility - ✅✅the tendency of a substance to vaporize
chemical agents (WMD) - ✅✅nerve agents (VX, sarin)
