FE EXAM (CHEMICAL) QUESTIONS
AND VERIFIED ANSWERS|100%
CORRECT|GRADE A+
Fluid property most related to flow? - ANSWER Viscosity
PRVs are used in wine fermentation to prevent over-pressurization from which of the following yeast
reactions? - ANSWER The yeast produces carbon dioxide during fermentation.
Metals with high hardness will also have which of the following characteristics? - ANSWER Strong
intermolecular bonding, high tensile strength, high yield strength, and high abrasion/scratch resistance.
If an aluminum crimp connector is used to connect a copper wire to a battery, what would you expect to
happen? - ANSWER Only the aluminum connector will corrode (aluminum is anodic(electrons removed
from surface) and will corrode to protect the copper).
Glass is an amorphous material, which means that: - ANSWER It has no apparent crystal structure.
The # of hydrogen atoms in a molecule of dodecane is: - ANSWER 12 (do-two, decane-10)
Which analytical equipment provides the best method to analyze the Hg concentration to PPM in a
groundwater sample. - ANSWER Atomic adsorption unit.
Air from a 100 psig source is free-flowing down a long pipe discharging to the atmosphere. This is an
example of what kind of fluid flow? - ANSWER Compressible flow.
What is characterized by compressible flow? - ANSWER Changing density (i.e. the density of a gas
flowing from 100 psig source to atmosphere will change down the pipeline).
What occurs at an azeotrope? - ANSWER The vapor and liquid components of a mixture are the same.
