Question 3 • (AG Q3) Science 8: 25-26 (ELux)

A thermogram taken outside a house shows high amounts of thermal energy around the windows but not around the roof.Which conclusion supports the thermogram?

Answer
A
The windows and the roof are energy efficient.
B
The windows and the roof are not energy efficient.
C
The windows are not energy efficient, but the roof is energy efficient.
D
The windows are energy efficient, but the roof is not energy efficient.

Explanation

High thermal energy around the windows indicates that heat is escaping there, so the windows are not energy efficient. Little thermal energy around the roof indicates little heat loss, so the roof is energy efficient. Therefore, the supported conclusion is that the windows are not energy efficient, but the roof is energy efficient.
