A model shows what a gas looks like on a molecular level.
A demonstration of how intermolecular forces account for a substance's phase.
See how kinetic energy is distributed when two substances of different temperature are mixed.
Phase change at a molecular level. Temperature and total energy are plotted on a line graph.

In this activity, students explore phase change at a molecular level. They trace the path of an atom to view intermolecular interactions and investigate how temperature relates to phase change. Upon activity completion, students will be able to give examples of phase change, explain how the input of energy into a system affects the state of matter, and describe how both latent heat and evaporative cooling play a role in changes of phase.
