Normally, things expand when heated and contract when cooled. Water is an exception
to this rule. Even though water does expand when heated and contract when cooled at
most temperatures, water expands when cooled and contracts when heated between 4
degrees Celsius and 0 degrees Celsius.
A very good web site about the properties and oddities of water can be found on the
Okanagan University, Dept. of Geology website at:
