In what the uniqueness? great solvent properties due to polarity and hydrogen bonding ability; exceptional high specific heat capacity; high surface tension and capillarity; density differences of liquid and solid states.

great solvent properties due to polarity and hydrogen bonding ability;

exceptional high specific heat capacity;

high surface tension and capillarity;

density differences of liquid and solid states.

Bent molecular shape

Unique solvent properties of water result from its polarity and exceptional H-bonding ability.

Unique thermal properties of water result from its exceptionally high specific heat capacity and heat of vaporization.

Hydrogen bonds in oceans

Unique surface properties of water are high surface tension and high capillarity. These result from abundant H-bonds.

Capillary action of water

Density differences of liquid and solid states of water result from large spaces within ice.

Ice is lighter
