Water: Latent & Specific Heat

Lab Summary

Use a temperature sensor and stainless steel temperature probe to measure the energy transfer required to change the temperature of water and then determine the latent heat of fusion of water.

Theory

Ice at temperature Ti and mass mi is added to hot water of temperature Tw and mass mw. The ice is allowed to completely melt and establish thermal equilibrium with the water. Design and conduct an experiment that will measure the energy transfer required to change the temperature of water, and then experimentally measure the latent heat of fusion of water.

  • Measure the equilibrium temperature between two substances.
  • Determine the latent heat of fusion of water.
  • Using the specific heat of water, determine the energy needed to change the temperature of water a known ΔT.

Method

Students gain experience conducting the following procedures:

  • Determining the latent heat of fusion of water by mixing a set amount of ice and heated water and then recording the initial (before mixing) and final (thermal equilibrium) temperatures .
