A 0.95-kg sample of water at 11°C is in a calorimeter. You drop a piece of steel with a mass of 0.39 kg at 212°C into it. After the sizzling subsides, what is the final equilibrium temperature? Make the reasonable assumptions that any steam produced condenses into liquid water during the process of equilibration and that the evaporation and condensation taken together don't affect the outcome, as we'll see later.
