WATER OUR LIFELINE Water is a transparent fluid which forms the world’s streams‚ lakes‚ oceans and rain‚ and is the major constituent of the fluids of living things. As a chemical compound‚ a water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds. Water covers 71% of the Earth’s surface.[1] It is vital for all known forms of life. On Earth‚ 96.5% of the planet’s water is found in seas and oceans‚ 1.7% in groundwater‚ 1.7% in glaciers and the ice caps of Antarctica

Water is a chemical compound with the chemical formula H2O. A water molecule contains one oxygen and two hydrogen atoms 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 (water vapor or steam). Water also exists in a liquid crystal state near hydrophilic surfaces. Water is considered a purifier in most religions. Major faiths that incorporate ritual washing (ablution) include Christianity

What is Alkaline Water? Alkaline water‚ also commonly known as ionized water‚ is water that has a pH level greater than seven. This water is generally produced with the aid of a faucet-based water ionizer‚ or "alkalizer" and features a number of health benefits. Making Alkaline Water These are some of the possible sources of alkaline water: * Lemon (& Lime) Water * pH Drops * Alkalising Powder * Mainstream Water Filters * Water Distillers * Reverse Osmosis * Alkaline

Illuminate how water affects the external processes on the slope of Hong Kong. Explain how these external processes shape the slope landscape in Hong Kong. Chemical weathering involves the decomposition of rock due to the alteration of rock minerals by chemical reactions between the rocks and the water with which they come into contact. Chemical reaction causes certain minerals to change into more vulnerable ones. This weakens the internal structure of the rocks‚ and leads to decomposition. Moisture

Deionized Water vs. Distilled Water Deionized and distilled waters are both processed forms of water. Deionized water is produced by filtering water to the point where it is free of ions. This ion-free water will strip ions from surrounding material‚ acting like a super-solvent. This is often used in semiconductor and other high-tech processing as a "soft" solvent and relatively cheap cleaning fluid. Distilled water is most often produced by vaporizing less pure source water (tap‚ salt or even

GROUND WATER THE WATER/HYDROLOGIC CYCLE * Composed of evaporation from the oceans * Movements of moist air inland * Condensation and precipitation * Run-off on the surface or sub-surface back to the ocean * Plus additional minor cycles * Involves the exchange of water with the atmosphere‚ the earth‚ and the different water forms * Done when clouds gain water vapor from the various water forms * Evaporation – process where water turns into steam or gas when the

Water is called “the elixir of life”. This is‚ indeed‚ the name which the Indian Nobel Laureate‚ C. V. Raman‚ has given it in his celebrated essay of the same name. The earth comprises two thirds of water and one third of land. Water is essential for all living beings. There can be no life without water. Human beings‚ animals and all kinds of plants all need water. Much of the beauty of the earth is because of the presence of plenty of water on it. The main sources of water are rain‚ rivers
