Exam 2026 Questions and Answers
Adsorption - Correct answer-the collection of one substance on the surface of
another
Absorption - Correct answer-the process or action by which one thing absorbs or is
absorbed by another.
Alkali - Correct answer-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 - Correct answer-Number assigned by the American Chemical
Society's Chemical Abstract Service that uniquely identifies a specific compound.
Corrosive - Correct answer-having the tendency to erode or eat away (The effect of
the chemical was highly corrosive.)
Flash point - Correct answer-Minimum temperature at which a liquid gives off
enough vapors to form an ignitable mixture with air near the liquid's surface.

, Flame point - Correct answer-The lowest temperature at which a liquid produces
enough vapor to sustain a continuous fire.
Ignition temp - Correct answer-the minimum temperature at which fuel vapor will
ignite
Miscibility - Correct answer-The degree to which two liquids can mix.
MSST - Correct answer-maximum safe storage temperature
Oxidizer - Correct answer-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 - Correct answer-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 - Correct answer-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 - Correct answer-A change directly from the solid to the gaseous state
without becoming liquid
Vapor Density - Correct answer-weight of a vapor compared to air
