In summer, a family assembled a patio set for their deck. Most of the assembling was done by placing metal screws into parts of the furniture. The furniture was stable all summer. However, when the weather turned cold in the late fall, the family noticed that the chairs and table became wobbly. Use your knowledge ofthermal expansion to explain why.
