Enthalpy of Fusion for Ice

Applying Concepts When ice is added to water at room temperature, the water provides the energy for two processes. The first process is the melting of the ice. The energy required to melt ice is the enthalpy of fusion (AHfus). The second process is raising the temperature of the melted ice from its initial temperature of 0.0°C to the final temperature of the liquid water. In this experiment, you will collect data to calculate the enthalpy of fusion for ice. 

Materials foam cup, thermometer, stirring rod, ice, water, balance 

Measure the mass of an empty foam cup and record It In your data table. 

Fill the foam cup about one-third full of water. Measure and record the mass. 

Place the thermometer in the cup. Read and record the initial temperature of the water.
