TLF ID L9122
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 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 a combination of two objects in the same series.
