PLTW CEA FINAL EXAM 2026 STUDY
GUIDE COMPREHENSIVE
QUESTIONS ANSWERS VERIFIED A+
◉ Concrete.
Answer: A solid, hard material produced by combining Portland cement,
aggregates, sand, water and sometimes additional mixtures.
◉ Design Temperature Differential.
Answer: The difference between the indoor temperature in winter and
the outdoor design temperature in winter. The design temperature
differential or design range is used in calculating the space heating
requirements of a dwelling unit under the engineering-based
methodology.
◉ Fascia.
Answer: The finish board covering the edges of rafters and eaves.
◉ Footing.
Answer: The lowest, widest part of the foundation that distributes the
load over a broad area of the soil.
◉ Foundation.
Answer: The lower part of a building, which transfers structural loads
from the building to the soil.
,◉ Heat Loss.
Answer: The energy needed to warm outside air leaking into a building
through cracks around doors, windows, and other areas.
◉ Radiant Heat.
Answer: Energy radiated or transmitted as rays or waves, in the form of
particles.
◉ Rafter.
Answer: Member of a roof structural frame that supports the sheathing
and other roof loads.
◉ Rebar.
Answer: Steel bar used to reinforce concrete.
◉ R-Value.
Answer: The numerical value used to indicate the resistance to the flow
of heat.
◉ Sole Plate.
Answer: The plate placed at the bottom of a wall.
◉ Square (Quantity of Shingles).
Answer: In roofing, 100 square feet of roofing material.
, ◉ Tensile Strength.
Answer: The maximum stress a material subjected to a stretching load
can withstand without tearing.
◉ Thermal Conduction.
Answer: The process of heat transfer through a solid by transmitting
kinetic energy from one molecule to the next.
◉ Thermal Convection.
Answer: Heat transmission by the circulation of a liquid or a heated gas
or air.
◉ Transmission Load.
Answer: Heat loss/gain resulting from the conduction of heat through
the building envelope.
◉ U-Factor.
Answer: A measure of the heat transmission through a building part (as
a wall or window) or a given thickness of a material (as insulation) with
lower numbers indicating better insulating properties.
◉ Aesthetics.
Answer: the quality of an objects that deals with art, beauty, and taste
