During melting, heat is absorbed by the melting solid. In this experiment, you will determine how much heat is needed to melt 1 g of ice. Heat has units of joules (J). The heat used to melt the ice will come from the cooling of warm water and will be measured with a calorimeter. A calorimeter is an insulated container fitted with a device for measuring temperature. You will use a simple calorimeter made of a Styrofoam cup, a 250 mL beaker, and a Temperature Probe.


In this experiment, you will

  • Use a calorimeter.
  • Make temperature measurements.
  • Analyze the data collected.
  • Determine heat of fusion for ice (in J/g).
