Question 11

11.

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 of
thermal expansion to explain why.

When you touch a warm picnic table, your hand becomes warmer. Explain energy conservation and how heat transfers.

Question 22

22.

What is thermal equilibrium?

Question 23

23.

What kind of energy does friction cause? Hint-it's the title of this unit of study. You can see the example of a baseball player sliding into a base causing friction. Give a different example of friction happening than the examples shown here.

Question 24
