Water

Chemical compounds consisting of two hydrogen and an oxygen atom.

Three states of water: liquid, solid (ice), and mixed with air (invisible) water vapor. Cloud is a composite of water-soluble air in the air.


Water or water is a chemical substance, its chemical signal is H2O. Each water molecule is composed of an oxygen atom and two hydrogen peripherals. Usually water in the liquid is in the water, but it is also difficult (in ice) and in aerial conditions (water vapor) is found. Water also exists in the form of liquid crystals in the world. According to the nomenclature of the chemical compound, the scientific name of the water is dihydrogen monoxide. But this name is not used almost anywhere.

Water is present in 70.9% of the surface area and water is an essential element for the life of almost all living organisms. 96.5% of the water obtained in the oceans is available in the oceans, 1.7% underground, 1.7% as iceberg and snow, a small part of the other large ponies and 0.001% in the atmosphere, clouds, water vapor and precipitation, frost, etc. . Only 2.5% of the world's water is pure water and the rest 98.8% is underground water and ice. Less than 0.3% of pure water is found in the rivers, lakes and the atmosphere, and even lesser parts are found in the bodies and products of different organisms. Throughout the water cycle, water is constantly evaporated, condensate, evaporative, etc. Due to evaporation and vaporization, rainfall, frost, etc. occurs on the earth.

Supplementary water is essential for the life of other people, including the human race. Over the past few decades, the supply of supplemental water has increased in almost all parts of the world. But still about one billion people are safe water and nearly 250 million people are deprived from health-care facilities. With the use of safe water, there is a clear correlation of the total domestic production of per capita. Some observers estimate that by 2025 more than half of the world's population will face water related problems. According to a recent report published in November 2009, water demand exceeded 50% in comparison to some of the developing regions by 2030. Water plays an important role in the global economy because the water serves as the solvent of many chemicals and helps to cool down and transport in different industries. About 70% of the pure water used is used in agriculture.

Chemical and physical property

A wave of water strikes the capillary waves in the water and temporarily fades like a fountain
Dew is torn in the spider web. The chemical signals of water compared to parasitic and parallel vertebrates are called H2O: Two hydrogen atoms in a water molecule are bonded to an oxygen atom. Water exists in the world in three conditions of matter. Water is found in the sky as water vapor and clouds, ocean as ocean water, oceans in the pole region, glaciers and rivers, and the presence of water in the oceans and the underground water. Under the large planets, the water is in the water at high pressure and temperature. In that state, water molecules break down and form a medium of hydrogen and oxygen ions. Even with more pressure oxygen is released, hydrogen ions float freely in the structure of the oxygen ellis celace. This special situation is called the overdue state of water.

The main physical and chemical properties of water

source
Normal pressure and water temperature in the fluid. Water is taste and odorless Although the color of water and ice is slightly blue, both of them appear colorless when present in small quantities. Watery vapor is colorless, hence the disappearance.
Being transparent in visible electromagnetic spectrum, the sun's light can enter the water, which plays an important role in the life of aquatic plants. Although almost whole of ultraviolet and infrared rays are absorbed in water.
Because the electronegativity of the oxygen atom is higher than that of hydrogen, it has a slightly negative electrical current and hydrogen atoms are slightly more positive electromagnetic. This results in the formation of a bipolar fracture in water molecules. For this religion, water molecules can produce unusually large number of inter-hybrid hydrogen bonds compared to its size. For these reasons, the cohesion force is very strong among water molecules. That is why the surface of the water and the capillary force are high. The tendency of rising upwards of water against gravity by a very narrow tube (capillary tube) is called capillary action. For this religion of water, living plants can absorb water from the soil. Water can dissolve almost all electromagnetic substances because its water is bimetermic. Also, many copulatory materials are also dissolved in water as a very good solvent in the water chemical laboratory. For this reason, water is sometimes called universal solvent. Some of the substances that are dissolved in water are: salt, sugar, acids, alkaline, several gases, especially oxygen, carbon dioxide etc. There are also some substances that are not particularly dissolved in water. Such as oil, grills etc.

Taste and smell

Different types of materials can dissolve in water & cause different flavors and odors. People & other animals are able to feel any water that they can be able to feel by their senses. No animals drink salted or contaminated water. The taste found in the water of the fountain water and the mineral mixture is derived from the minerals mixed in the water. But pure water is completely tasteless and odorless. The purity that is claimed in the commercial mineral water commercially refers to the absence of any kind of germs, pollutants, or poisons in the water. In fact, the water is not pure because it contains several minerals.

Biological effects

Water effects in the biosphere are immense. Without water, life on earth would not have existed. Water is also essential for human essentials. A person can survive only for three days without water.

Health and pollution

source
Pure water is very important for keeping good health. By drinking contaminated water the human body is affected by various types of diseases. Due to drinking contaminated water, especially kidneys are affected. Many of us are not careful about drinking pure water. Those who live in the city try to eat at least water. People of the city usually use tank water. Due to not cleaning the tanky for many days, the tank is full of shawl and dirt. Many of us do not pay attention to it. We will try to clear the water tanks. Then we will be released from various diseases of water.

Agriculture

source
The most important use of water in agriculture is the use of irrigation. Approximately 90% of the water used in some developing countries is used, and in the economically developed countries, lions of water are used only as irrigation (about 30% of pure water in the United States is used for irrigation).

Drinking Water

source
In relation to the size of the human body, it contains 55% - 78% water. The human body needs one to seven liters of water per day to stay active & to prevent dehydration. Depending on the actual amount of water required by the body, the amount of activity, temperature, humidity, etc. Most of the total amount of water taken in the body comes from drinking water directly instead of drinking water & other beverages. Although the amount of water needed for a healthy person is not clearly defined, most experts have expressed that the need for water is approximately 2 liters (6 to 7 glasses) per day.

source
Due to the lack of water emitted by the body due to exercise or hot weather, medical literature generally gives 1 liter of water for an average person, which means to drink a little water. It is inconvenient for people who have healthy kidneys to drink excessive water but if they are exercising or having wet weather, drinking a little water becomes dangerous for the body. A person can drink excess water while doing exercise, but it can cause excessive addiction towards the water, which is harmful to the body.

The idea that a person's daily need to drink eight glasses of water is most commonly known, in science it probably has no real basis. Likewise, the misconceptions regarding the benefits of drinking water in reducing weight loss and constipation are also disproportionately discarded.
