Specific heat means the heat required to raise the temperature of the unit mass of a given substance by a given amount (usually one degree).. The specific heat of water is high (1 calorie/gm/°C). This property ensures slow heating of water; maintain constant temperature of living organisms and environment.
Expansion upon freezing is what causes ice to be less dense as a solid than as a liquid. This means that ice floats in liquid water. Hydrogen bonding is the source of this rare property. Water freezes when its molecules are no longer moving around enough to break their hydrogen bonds.even though it doesn't seem like a very important property, but the fitness of the environment would drastically change if water were less dense than ice. All of bodies of water would eventually freeze over if ice did sink, making life on Earth impossible.
Versatility as a solvent Water is called the "universal solvent" because it dissolves more substances than any other known liquid. This is important to every living thing on earth. It means that wherever water goes, either through the ground or through our bodies, it takes along valuable chemicals, minerals, and nutrients.

Answer:
the difference is due to the fact that one water molecule has two hydrogen atoms to one oxygen this means it takes two water molecules (2 H2O) to make one oxygen molecule (02) .At the same time however two molecules of water (2 H20) can make two molecules of hydrogen (2 H20)
