EGEE 101 – Final Exam 3 Completed Set – Energy and Environmental
Engineering – complete exam material
________ is a product of hydrocarbons, ground level ozone, and sunlight. Cities
such as Los Angeles and Mexico City are famous for it. - ANS ✔✔Smog
True or False: Atmospheric ozone can be thought of as tanning oil for a sunbather
- ANS ✔✔False
What is the value of: 5.35 X 104. - ANS ✔✔53500
The following illustration shows what (graph w/ ground level, altitude and temp)?
- ANS ✔✔The phenomenon of cool air being trapped by a layer of warm air
A _______ reduces (or increases) the amount of energy required to initiate a
reaction. Commonly present in exhaust systems of vehicles. (I am expecting a one
word answer) - ANS ✔✔Catalyst
What does the number "10" stand for in the name PM10? - ANS ✔✔The
number represents particles < 10 microns
Modern cars pollute less than older cars. How much has the improvement been in
emission reductions? - ANS ✔✔20 times less
The following diagram (has reaction coordinates, energy, endothermic start &
finish, and activation energy) is useful in showing the amount of energy required
to initiate a chemical reaction (activation energy). What effect does a catalyst
, have on the activation energy? - ANS ✔✔Catalyst will increase or decrease the
activation energy of a reaction
True or False: Smog is caused by the ozone hole. - ANS ✔✔false
Select all of the following devices which can be used to control particulate
emissions from a power plant: - ANS ✔✔Cyclone Separators Fabric Filters (bag
houses) Electrostatic Precipitators Wet Collectors
During what season is smog most likely to be in the highest concentrations? (hint:
think about the ingredients to form smog) - ANS ✔✔summer
True or False: CFC's (chloro-fluoro-carbons) like those which were used in the past
in vehicle air conditioners destroy the ozone layer - ANS ✔✔true
Read through this article about the Donora, PA air pollution disaster. What caused
the emissions to stay near ground level and not disperse into the atmosphere? -
ANS ✔✔A temperature inversion
Given the following diagram: what can you say about an endothermic reaction -
ANS ✔✔It is necessary to add energy to the reaction to get products (usually
done by increasing the temperature)
What common fuel material contains approximately 0.5% to 5% in weight of
sulfur? type the correct answer (hint: It is also the fuel used to generate a large
portion of the electricity in PA) - ANS ✔✔Coal
