Learning objects Interpreting changes of state: cooling

TLF ID L9129

Predict the shape of the graph when water vapour is cooled to solid ice. Observe physical and particle animations of the changes that occur during cooling and confirm prediction of graph shape. This learning object is the second in a series of two sequential objects that are also available as a combined learning object.

Educational details

Key learning objectives
  • Students observe the behaviour of water particles during cooling and explain properties of solid, liquid and gaseous water, and the processes involved in changing state, in terms of kinetic theory.
  • Students predict the graph that will be obtained if water is cooled.
  • Students interpret and explain the shape of the temperature–time graphs obtained when water is cooled.
Educational value
  • Demonstrates how particle theory and the kinetic theory of matter can be used to explain properties of water and the physical changes that occur when it is cooled.
  • Provides physical and particle level animations showing water as it changes state between its solid, liquid and gas forms.
  • Includes options to print the data tables, graphs and summaries describing the changes in water when it is cooled.
  • Provides additional extension questions as an optional printout.
