Calculate the final temperature when a 16.2 gram sample of ice at 0oC is placed into a styrofoam cup containing 128 grams of water at 79.0 oC. Assume that there is no loss or gain of heat from the surroundings.

Heat of fusion of ice = 333 Jg-1
Specific heat of water = 4.184 JK-1g-1

Final temperature = oC

Calculate the entropy change that occurs during this process.

Entropy change = JK-1
