SDO
Systemic Diagram (SDO) represents systemic unknownRelations between physical properties of water
By studying the relations (1 2), and (A c)We can change (SDO) to (SD1) by adding these relations
(I)Formation of water molecules by covalent bonding
(V)Abnormality In physical properties
(III) Polar solvent
(IV) Hydrogen bonding
(II) Polarity of water molecule
(VI)State of water

Systemic Diagram (SD2) with known Relations (1 – 4, A – C, and G H), the rest of the
Relations are unknown
By studying the relations (5 –8), and (D-F) we can change (SD2) to (SDf) in which all the relations are known
