Say I have a metal and I heat it up to some temperature T. Then I dunk it in isolated water of temperature t, water which is fairly cool (t << T). Eventually, the metal and the water are at some final temperature Tf. The specific heat of the substance is calculated by: c = (Mass of water)(Specific heat of water)(Change in water temp) / (Mass of metal)(Change in metal temp) I perform the experiment a bunch of times and consistently get about the same specific heat c. Now, what would happen if halfway through the cooling process (where the water and the metal are becoming the same temperature), I poured some boiling water into the container holding the water and the metal? What would happen to the calculated specific heat? Would it drop or raise? Or would it stay the same? And why? Thanks!
