The Biological Importance of Water! The ultimate importance of water is none other than the fact that life cannot exist without it. Water being the major component of our body cells‚ typically making 70-95% of it‚ constructs the body mass with approximately 80% being water. Humans are not the only ones who contain the valued material but other creatures like the jellyfish hold 96% of water as their body mass. The structure of the water molecules enables it to have extreme properties that are

| Desalinization of Water | | | Sara Reed‚ Myp2 | | Chemistry | | * Our world consists of 70% of water‚ from which‚ only 2.5% is fresh water‚ and 1% is drinkable water. Because of this low drinkable water rate‚ desalinization is a very important process which will help us provide a higher percentage rate. * Desalination is a process in which salt water is turned into fresh water‚ by extracting its water and minerals. Desalination is used on many ships and submarines

Water is a chemical compound with the chemical formula H 2O. A water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds. Water is a liquid at standard ambient temperature and pressure‚ but it often co-exists on Earth with its solid state‚ ice‚ and gaseous state‚ steam (water vapor). Water covers 71% of the Earth’s surface‚ and is vital for all known forms of life.[2] On Earth‚ 96.5% of the planet’s water is found in seas and oceans‚ 1.7% in groundwater‚

specific heat is one of five properties of water that is important to life. Specific heat is defined as the heat necessary to raise one gram of water by one degree Celsius. Because water’s temperature does not change dramatically when absorbing or losing heat‚ water can absorb or release exceeding amounts of heat (by breaking and forming hydrogen bonds) without affecting living organisms in the water and at the same time helping terrestrial organisms outside the water live easier. For example‚ coastal areas

WATER LOGGING AND SALINITY Naheed Ghazanfar Izhar & Associates Consulting 5.1 CLASSIFICATION OF WATER LOGGED AND SALINE AREAS BY DEGREE The existing irrigation system in Khyber Pakhtunkhwa was developed in late 1800s over a century ago. This system was designed for the farming at that time which was much lower than the cropping intensities of today. This system had limited provision for drainage‚ resulting in a rise in groundwater and the occurrence of salinity. |Table

Water is the most abundant molecule on Earth’s surface. It is essential for life on Earth. The unique properties of water makes life possible on earth. One property of water is surface tension. Water has a surface tension 2 – 4 times the surface tension of most organic liquids. Surface tension is highest for pure water. This enables insects called neuston to walk and live on the surface of water in low-nutrient water bodies‚ where they would starve if immersed in the water. This anomaly permits

The Water Cycle Intro How come we never run out of water? After millions of years you’d think that our water supply would be all used up right! It’s not though‚ because of one special process‚ the hydrologic cycle‚ more commonly known as "the water cycle." Main Points This water cycle recycles the Earth’s water supply. In other words‚ the water keeps getting reused over and over. Just think‚ the next glass of water you drink could have been part of a dinosaur’s bath‚ one
