*The normal [[melting point]] of water is 32 degrees Fahrenheit (liquid state).
+
*The normal [[melting point]] of water is 32 degrees Fahrenheit, or 0 degrees Celsius (liquid state).
 
*Below 32 degrees Fahrenheit, water is normally in the solid state.

The chemical formula for water is H<sub>2</sub>O, two [[hydrogen]] and one [[oxygen]] [[atom]].  
+
The chemical formula for water is H<sub>2</sub>O, two [[hydrogen]] and one [[oxygen]] [[atom]], or dihydrogen monoxide.  
    
The shape of the water [[molecule]] is a shallow V, with the oxygen in the middle and having an angle of approximately 105°. The interactions between the atoms result in the oxygen atom having a partly negative charge and the hydrogen atoms having a partly positive charge. Thus the water molecule is a strong electrical [[dipole]], which accounts for some of its properties.
