And the six properties:
1. Surface tension; the surface tension of water is particularly high.
2. Elevated specific heat capacity.
3. Elevated specific heat of vaporization.
4. Unusual density of liquid VERSUS solid water. That ice floats on LIQUID water is a HIGHLY unusual property for a liquid. Normally the solid-phase would be DENSER than the liquid phase. The peculiar structure of liquid water at 4 ∘, which is a consequence of hydrogen bonding, gives rise to the density. That water is exceptionally dense, certainly denser than most organic solvents, also reflects this property.
5. Elevated boiling point. The normal boiling point of water, which of course is 100 ∘C is RIDICULOUSLY high. You compare this with other small molecules, NH3, CH4, NO2, SO2 etc. and the boiling point of water is EXCEPTIONAL.
6. Elevated melting point. The normal melting point of water at ?? is again exceptional, and unusual.
7. Properties as a solvent. Water is a protic, POLAR solvent, which can solvate MOST substances. The polarity of the water molecule, i.e. δ+H−δ−O−H, which solvates anions, and cations, is the basis of this property.
I included this property because perhaps the other categories overlap somewhat.
You happy with this? The properties do overlap as I said.....
