What is the final temperature, (in oC), after a 20.0 gram piece of ice at 0oC is placed into a styrofoam cup with 118.0 grams of water initially at 78.0oC? Assume no loss or gain of heat from the surroundings. Enter your answer without units. heat of fusion of water is 333 J/g. The specific heat of H2O(l) is approximately constant at 4.184 J/gK.
