Basics Types And Uses Of Water (H2O)
Water is a essential for living things. The base of whole world is on water. We are living here in this world because, the ratio of earth is about 71% included water and just about 29% is other stuff.
The Water include Oxygen and Hydrogen. The ratio between Oxygen and Hydrogen is 1:2. The one molecule of Oxygen reacts with two molecules of Hydrogen to make water, they are connected by covenant bond. The density of water is more when it is in liquid form as compare to when available in hard form like Ice. The boiling point of water is 100 degree centigrade. But it makes some variation when the atmospheric pressure changes like in mountains or in Pressure Cooker. Due to this behavior we got benefits , like to make or cook food quickly.
It also occurs in nature as snow, glaciers, ice packs and icebergs, clouds, fog, dew, aquifers, and atmospheric humidity. Basically, pure Water is a transparent, tasteless, odorless, and nearly colorless chemical substance that is the main constituent of Earth’s streams, lakes, and oceans, and the fluids of most living organisms. Although watrer has no colour but we can live only below than a week without water. We can not even think about the life without water. Scientists try a lot to find Water in other Planets but they are not fully satisfied yet . There is a chance of occuring watrer in Moon, that could help to live their.
Pure water is a less electric conductor, the conductivity increases when it dissolve the other ionic materials more like SALT , which has a common formula includes calcium and chloride.
Liquid water can be split into the elements hydrogen and oxygen by passing an electric current through a process called electrolysis. The decomposition requires more energy input than the heat released by the inverse process. Water fit for human consumption is called drinking water or potable water. Water that is not potable may be made potable by filtration or distillation, or by a range of other methods. Now a days, due to shortage of water filtration becomes so essential as we are already suffering from short amount of water. Water that is not fit for drinking but is not harmful for humans when used for swimming or bathing is called by various names other than potable or drinking water, and is sometimes called safe water, or “safe for bathing.
This is the need to make water useable again from it has already used. In the US, non-potable forms of waste water generated by humans may be referred to as greywater, which is treatable and thus easily able to be made potable again, and blackwater, which generally contains sewage and other forms of waste which require further treatment in order to be made reusable.
In daily routine the main use of water is in agriculture field to grow something to eat.
The most important use of water in agriculture is for irrigation, which is a key component to produce enough food. Irrigation takes up to 90% of water withdrawn in some developing countries and significant proportions in more economically developed countries (in the United States, 30% of freshwater usage is for irrigation).
It has also other major usage except Agriculrure in daily routine The propensity of water to form solutions and emulsions is useful in various washing processes. Washing is also an important component of several aspects of personal body hygiene. Most of personal water use is due to showering, doing the laundry and dishwashing, reaching hundreds of liters per day in developed countries. Similarly, water is a main componet use in transport purposes as well as in othre depart of life. There are thousands of working industries of water available in the whole world that make water clean by purification and provide it to people.
These kind of steps to clean water should be taken world widely, so that we can use water again that has no harm to people after drink. It can cause the main factor to overcome the difficulties occurring due to the shortage of water.
