This gives the reader a very detailed insight on water. It goes into the electronegativity of water, how water bonds, waters adhesive tendancies and other properties of water. Basically it counts up most of the ways water is significant to life on earth and what makes water the basis of life itself. Water is a substance whose molecule is made from two 1hydrogen atoms and one 16oxygen atom (H20) and that is in a liquid state at room temperature. It boils at 100ÃÂºC and melts at 0ÃÂºC. Water is probably the fundamental reason for sustenance of life on Earth. Every living thing depends on it to survive which is why water is so important. As well as being essential to life, water also has many other uses. Some of these include being a very good solvent, for washing or even as habitats and environments. Water's abundance and requirements towards life already make it special.
The use of water as a solvent in humans is very extensive. A main function is to transport materials around the body to where they are needed. Blood plasma, tissue fluid and lymph are all predominantly water and are used to dissolve a wide range of substances which can then be easily transported. It dilutes waste products in order to safely remove them from the body such as ammonia and urea.
