25lines about water
Answers
Answer:
Water is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, even though it provides no calories or organic nutrients. Its chemical formula is H2O, meaning that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. Two hydrogen atoms are attached to one oxygen atom at an angle of 104.45°.
"Water" is the name of the liquid state of H2O at standard ambient temperature and pressure. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds are formed from suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitate in the form of snow. The gaseous state of water is steam or water vapor. Water moves continually through the water cycle of evaporation, transpiration (evapotranspiration), condensation, precipitation, and runoff, usually reaching the sea.
Water covers 71% of the Earth's surface, mostly in seas and oceans.Small portions of water occur as groundwater (1.7%), in the glaciers and the ice caps of Antarctica and Greenland (1.7%), and in the air as vapor, clouds (formed of ice and liquid water suspended in air), and precipitation (0.001%).
Water plays an important role in the world economy. Approximately 70% of the freshwater used by humans goes to agriculture. Fishing in salt and fresh water bodies is a major source of food for many parts of the world. Much of the long-distance trade of commodities (such as oil, natural gas, and manufactured products) is transported by boats through seas, rivers, lakes, and canals. Large quantities of water, ice, and steam are used for cooling and heating, in industry and homes. Water is an excellent solvent for a wide variety of substances both mineral and organic; as such it is widely used in industrial processes, and in cooking and washing. Water, ice and snow are also central to many sports and other forms of entertainment, such as swimming, pleasure boating, boat racing, surfing, sport fishing, diving, ice skating and skiing.
Answer:
Water is one of the most important substances for life on earth to function. It is equally important for humans as well as animals. Water does not merely help us survive, but it is significant for our day to day functioning. It has numerous uses when we come to think about it. Majority of our earth is covered with water itself, but, not all of it is safe for consumption. Therefore, it makes it essential for us to utilize this transparent substance chemical wisely. Moreover, if we look at the shortage of waterhappening in our country, it makes it all the more important to conserve it immediately. Essay on Water in English: Water, the very reason for the existence of living beings on earth, constitutes of more than 70% of the planet. Water is that magical liquid, that provides life to animals, plants, trees, bacteria and viruses. Water is the very reason why earth can support life and other planets cannot.
Up to 60% of the human body is made up of water. While there is an abundance of water on the planet, not everything can be consumed by human beings and animals. It is unfortunate that only 3% of the water on earth is freshwater, which is portable and safe to consume.
