Learning objects Matter and evaporation: liquid to gas

TLF ID L1493

Experiment with phase transformations of water. Heat a beaker of water to boiling point. Predict changes to the molecular structure and molecular motion. Look closely at movement of the water molecules, especially at the surface. Explore relationships between temperature, molecular speed and states of matter. This learning object is one in a series of three objects. The series is also packaged as a combined learning object.



Educational details

Key learning objectives
  • Students relate rising temperature of a substance to the increasing speed of its molecules.
  • Students describe the changes in molecular structure accompanying changes in state from liquid to gas.
  • Students identify that temperature remains constant until a change of state is complete.
Educational value
  • Students explore the changes that occur in speed and arrangement of molecules as water is heated to boiling point.
  • Students choose between two hypotheses.
  • The simulation is accessible for further observation after feedback has been given.
