A thermometer is the first thing I thought of
(a) including instructions like "You can NOT receive full credit without explaining HOW your examples use contraction and expansion." serves no purpose. I'm not interested in full credit, just helping you understand the question.
(b) no one sits here all day just waiting for you to ask a question. We live our lives, and check in from time to time to see what new questions have been posted. There is no guarantee anyone will see your question the instant you post it. Waiting till your answer is due is just foolish.
What are two examples of how we use the concepts of expansion and contraction due to temperature changes in every day life? EXPLAIN HOW they use expansion and contraction.
You can NOT receive full credit without explaining HOW your examples use contraction and expansion.
