Some students do not regard a change of state as being related to a specific temperature

Properties of Matter


Students may explain changes of state in terms of the macroscopic properties of substances; they may think that melting and boiling points are properties of a substance.

  • Change of volume: water to water vapour  (11-16)

    Ref - Practical physics; Molecules in motion; Change of phase; Change of volume: water to water vapour

    This experiment can be used to show that water changes to water vapour at a specific temperature.
