Description
Select a substance such as liquid water and explore how physical changes of state can be brought about by supplying heat energy to the substance. Observe what happens when heat energy is removed. Observe the changes of state at both the physical and particle levels. Explain the different properties of liquids and gases in terms of their particle movement. This learning object is one in a series of three objects. The series is also packaged as a combined learning object.
Objective
1. Students explain that changes of state occur when heat energy is added to, or removed from, a substance.
2. Students identify that changes of state such as evaporation and condensation are reversible physical changes.
3. Students describe the properties of liquids and gases in terms of their particles. During a change of state the particles of a substance do not change but their movement and the way they are packed together does change.
