| When
the temperature of water falls below 0ºC it changes to
ice. We say it freezes. In the same way,
we could say that wax freezes when its
temperature goes below 64ºC. A candle is a lump of
frozen wax in the same way as an icicle is frozen water.
Here we are using 'freeze' to mean a change from
liquid to solid. This is the scientific meaning
of the word. Freezing is the reverse process of melting.
