Answer:
C.
Explanation:
As should have been explained at the very start of the lesson, it states "Whatever goes up, must come down."
Engineers must understand the thermal properties of materials to be able
to predict the performance of any given material over its lifetime in a
specific application. Engineers apply their understanding of the
thermal properties of materials to the design of efficient heat transfer
materials for better engines, spacecraft and electronic devices. They
also examine the thermal properties of insulation to design more
efficient buildings and homes. Engineers develop ways to minimize heat
transfer from a motor to the surrounding environment. Often they find
ways to insulate the motor to decrease the convective heat transfer from
the motor. They design a refrigerator to keep heat out of the inside,
as well as keep the refrigerator contents cool. hope this helped
