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‚

the current water shortage on Oahu. For the purpose of this paper‚ our group has chosen to discuss what we believe to be the top three most feasible technological solutions. In order of current usability they are; 1. Water recycling 2. Desalination 3. OTEC (Ocean Thermal Energy Conversion) Water Recycling Water recycling here on Oahu is an important part of ensuring a sustainable water supply for future generations. Through the natural water cycle‚ the earth has recycled and reused water for millions

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

Paragraph on Water Water is a precondition of life. Besides various uses of water‚ it is mainly used in irrigation as India is an agricultural country. Water is a renewable resource. Life is impossible without water. Its uses are limitless whether it is in home or in fields or in industries. We get water mainly from rain‚ rivers‚ wells‚ ponds and lakes. Sea-water is almost useless for domestic or industrial purposes. India is said to be a Monsoon country. But the distribution of Monsoon rainfall

both these things water is needed so exploration of Mars by space probes has concentrated on looking for water. Humans have searched for evidence of water on Mars for many years. In 1895 American astronomer Percival Lowell thought that he had seen canals on the surface of Mars. These were disproved as tricks of the eye. Spacecraft in the 1960’s and 1970’s reported that Mars was very dry. However‚ spacecraft in the 1970’s to the 1990’s started to report evidence of water‚ either past or

Recycling water the natural way Natural water treatment at Siemens facility in India In a densely populated country like India‚ water is a very precious resource. Home to approximately 16 percent of the world’s population‚ India has but four percent of the planet’s water reserves. With this in mind‚ the location management of Siemens Real Estate in Kalwa‚ India and EHS opted to implement a wastewater treatment system that would‚ for the most part‚ regulate itself – much like a natural wetland
