This Activity Requires:

  • Java 1.5+ - Java 1.5+ is available for Windows, Linux, and Mac OS X 10.4 and greater. If you are using Mac OS X 10.3, you can download MW Version 1.3 and explore within it instead.

      Test your system to see if it meets the requirements

Important! If you cannot launch anything from this database, please follow the step-by-step instructions on the software page.

Please Note: Many models are linked to directly from within the database. When an activity employs our scripting language, Pedagogica, as do some of the "guided" activities, the initial download may take several minutes. Subsequent activities will not take a long time. See this page for further instructions.

Overview and Learning Objectives

Users can add heat to the system and see that there is a period in which the temperature ceases to rise.

Central Concepts

Key Concept:

Latent heat is the amount of energy a material absorbs or releases during phase transformation. It is called latent heat because it does not result in a change in temperature. For an isolated system, latent heat is usually associated with the rearrangement of atom positions in a phase transition.
