Alcohols, fatty acids, proteins, and many other organic compounds owe their existance to the reaction of organic molecules with water. While water is used both chemically and physcially, with both organic and inorganic substances, it has some characteristics that scientist still don't completely understand. Water molecules have a unique ability to be energized by microwave radiation, and at the same time make an excellent barrier to nuclear radiation. It absorbs neutrons in nuclear powerplants, yet is easily heated by microwaves. As abundant as water is and as familiar as it is, it is amazing what scientists can't explain about it.
Water has a very high surface tension though it is such a small molecule.
These and other questions have evaded complete explaination even today. Water still has some suprises left. Due to the existence of heavy hydrogen atoms of deutrium and trinium, water is the primary source of the raw materials needed for hydrogen bombs. Water also is the ideal source of hydrogen for the creation of Plasma, and the possible development of controlled fusion reactions. Water is a compound that we know so well yet know so little about.
