A 1.28kg sample of water at 10.0C is in a calorimeter. You drop a piece of steel with a mass of 0.385kg at 215C 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 don't affect the outcome, as we'll see in the next section.)
