Water is ... a good solvent due to its polarity. The solvent properties of water are vital in biology, because many biochemical reactions take place only within aqueous solutions (e.g., reactions in the cytoplasm and blood). In addition, water is used to transport biological molecules.

Because of cohesion, water molecules resist increasing their motion. (this is another way of saying that is water molecules resist the net breaking of hydrogen bonds). Consequently, water resists heating; water has a very high specific heat.

When an ionic or polar compound enters water, it is surrounded by water molecules. The relatively small size of water molecules typically allows many water molecules to surround one molecule of solute. The partially negative dipoles of the water are attracted to positively charged components of the solute, and vice versa for the positive dipoles.

[B]ecause those water molecules of its hydration shell do not readily hydrogen bond to the hydrophobic molecule, the presence of a hydration shell is energetically unfavorable. (that is, the water molecules would much rather be free to hydrogen bond with one another).
