Jacob works in a store that sells jeans. Jacob is stacking a new delivery of jeans to display on top of the old jeans so that they are touching. In Stack 1, the top pair of jeans is larger than the bottom pair. In Stack 2, both pairs of jeans are the same size as the bottom pair in Stack 1. What does the different amount of energy mean for the temperature of all four pairs of jeans, and how will the two top pairs of jeans compare in temperature after a while? Why?
