Question

14. Several days after a snowfall, the roofs of some homes on your street have almost no snow on them, while the roofs on other homes are still snow covered. Assuming they have all received the same amount of sunlight, give one reason for this observation related to thermal energy and insulation.

Answer 1

Yes, the reason for no snow over some houses are due to proper insulation and the solar thermal coil over the roofs of the houses.

Mainly those houses where the snow have melted soon the reason is good number of solar thermal coils in the roof of the houses or fiberglass insulation. The use of thermal coils will absorb the sunlight and transfer heat over the total roof of the house which will help the snows to melt soon. Or the use of fiberglass insulation system allows the house to maintain a proper warm temperature inside the housekeeping the cold air away.
