5. (This is a more challenging question!!) In the lab you have a 100. g piece of iron that is heated to 80.0 °C. You take this piece of iron and drop it carefully into a beaker containing 100. mL of water at room temperature ( 25 °C). Does a phase change occur? Does a chemical reaction occur? Calculate the final temperature of the water (and the iron piece).
