Description :
Our water is a marvellous solution – always on the move in the
cycle of nature – and a condition for all life. Water is always
changing form, from liquid to vapour to ice, and back again.
Water is cyclic and has been functioned this way for billions of
years. Every life on Earth depends on water; computer
simulation has shown that the DNA helix breaks apart if it is
modelled without water.
Water is a chemical union of hydrogen and oxygen. The water
molecule is a dipole; the atoms are joined in an asymmetrical
manner that gives one end a surplus of positive electrical
energy and the other end a surplus of negative electrical
energy. Water is heaviest not at 0°C, its freezing point, but at
+4°C. If it were heaviest at 0°C then ice would form first at the
bottom of rivers and lakes; the fish would die and the ice would
not melt in the spring. Would there be life on earth in that
event?
