Heat of Fusion

Lab Summary

Use a fast response temperature sensor and calorimetry to determine the heat of fusion for water.


Determine the heat of fusion for water. Through this investigation, students:

  • Use calorimetry to determine the energy exchanged.
  • Determine the molar heat of fusion of ice.
  • Observe and describe how temperature changes before, during, and after a phase change.


Students conduct the following procedures:

  • Record the temperature change of heated water resulting from the addition of ice cubes.
  • Use the data collected to calculate the heat of fusion of ice.
  • Evaluate the results by calculating the percent error from an accepted value.
