HELP PL??! Workers on a movie set are stacking fake glass to use in a scene. The diagram above shows the pieces of fake glass before they touch each other. Use the information in the diagram to answer the question.

Compare the temperatures of the four pieces of fake glass before they touch. Which pieces are warmer, which pieces are cooler, and are any pieces the same temperature as each other? After the top pieces and bottom pieces have been touching for a while, will the two bottom pieces be the same temperature or different temperatures? Explain how their temperatures will compare, and why.
