Follow the link above to start or download this activity.

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

This activity allows users to observe the relationship between phase change and kinetic/potential energies. Users have an opportunity to heat and cool helium, and observe the exchange of energies.

Students will understand:

the role of van der Waals attractions;

the connection between temperature change and condensation;

and will begin to consider latent heat.
