Whitaker · Answer 1

The correct answer is B. They must be cooler than the air inside the house.

Explanation:

The metal aluminum coils in the air conditioning work by absorbing the heat inside the house and releasing this energy outside. This is only possible if the coils are cooler than the air of the house, this is because heat is always transferred from hotter substances or materials to cooler ones rather than from cooler materials to hotter ones. In this way, coils absorb part of the heat inside and this decreases the temperature in the house. Thus, the metal aluminum coils must be cooler than the air inside the house.
