Answer
Different construction materials have different coefficients of linear expansion.
Work Step by Step
A house is built from different materials. Each material has its own coefficient of linear expansion.
For example, different types of wood have different coefficients of linear expansion.
When the temperature decreases, the lengths of elements of the construction shrink with varying rates. The materials with which the house is built are joined together, and adjust to the new lengths, producing creaking sounds in doing so.
