Heat ice and record the temperature and states of water at specified times. Plot a graph of temperature against time and relate sections of the graph to the states of water. Observe animations of water particles over time and explain the shape of the graph in terms of particle theory. Predict the shape of the graph when water vapor 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 a combination of two objects in the same series.
1. Students observe the behavior of water particles during heating and cooling and explain properties of solid, liquid and gaseous water, and the processes involved in changing state, in terms of kinetic theory.
2. Students record and graph changes over time as water is heated, and predict the graph that will be obtained if water is cooled.
3. Students interpret and explain the shape of the temperature–time graphs obtained when water is heated and cooled.
