Reason For Learning
Students relate the properties of water to the water molecule’s structure, polarity and bonding. They also explore the significance of water’s high specific heat capacity and latent heat of vaporisation for living systems and water supplies.
Learning Intention
Properties of water
• trends in the melting and boiling points of Group 16 hydrides, with reference to the nature and relative strengths
of their intermolecular forces and to account for the exceptional values for water
• specific heat capacity and latent heat including units and symbols, with reference to hydrogen bonding to account for the relatively high specific heat capacity of liquid water, and significance for organisms and water supplies of the relatively high latent heat of vaporisation of water.
