In this experiment, the heat of fusion of ice will be determined by adding an ice cube to a Styrofoam cup full of warm water (the calorimeter) and allowing the ice to absorb heat from water in the calorimeter in order to melt. The quantity of heat absorbed from the warm water can be calculated and from this the heat of fusion can be determined. MATERIALS Styrofoam cup thermometer ice cube Procedure 1. Mass the Styrofoam cup. Record the mass. 2. Fill the cup 3/4 full with 30 - 35 oC water. 3. Mass the cup and the water. Record the mass. 4. Measure and record the temperature of the water. 5. Place the ice cube in the cup. Mass the cup, water and ice cube. Record this mass. 6. Stir the water with the thermometer until all the ice has melted. Record the final temperature.

Calculate the mass of warm water in the cup. 2. Calculate the temperature change of the warm water. 3. Calculate the mass of the ice cube. 4. What is the change in temperature of the water created by the melted ice. 5. Calculate the HEAT OF FUSION for water in calories per gram. 6. Calculate the MOLAR HEAT OF FUSION. ((Hf))) 7. Calculate the percent error. The accepted value is 1440 cal/mole.
