Question

The use of fiberglass insulation in the outer walls of a building is intended to minimize heat transfer through the wall by what process?

a) conduction
b) radiation
c) convection
d) vaporization

Answer 1

A, conduction.

Step-by-step explanation:

Thermal conduction, by definition, is "a phenomenon that occurs through the interaction of neighboring atoms and molecules, transferring their energy/heat (partially) to their neighbors". Fiberglass insulation works mainly by preventing thermal conduction, as would a rubber handle of a pot on a hot stove.

Hope this helps!
