What water is and what water is

Water includes natural water (rivers, lakes, atmospheric water, seawater, groundwater, etc.) and artificial water production (water obtained by combining hydrogen and oxygen atoms through chemical reactions). Water (chemical formula: H2O) is an inorganic substance composed of hydrogen and oxygen, which is a colorless and odorless transparent liquid at room temperature and pressure.

Water is one of the most common substances on Earth, an important resource for the survival of all life, including humans, and the most important component of living organisms. Water has played an important role in the evolution of life. Human beings have long begun to understand water, and water is regarded as a basic component in the ancient simple material concepts of the East and the West, and water is one of the five elements in ancient China. Water is also present in the ancient Western theory of the four elements.

Water is the main component of human cells and body fluids, and water plays a vital role in the body's metabolism.

According to scientific determination, the average value of various chemical elements and trace elements in human blood is closely related to the abundance value of elements in the earth's crust. Mineral water dissolves the minerals in the relevant strata of the earth's crust, so the essential trace elements and minerals contained in mineral water are also closest to the natural state of the human body. Nutritionally speaking, minerals and trace elements play no less important role in the human body than vitamins, and their role is much greater than what we realize.

Someone said: "The minerals and trace elements we need mainly come from food, and the absence of minerals in water does not affect the overall situation." "As an essential and beneficial for the human body of a dozen trace elements:

Iron, zinc, silicon, strontium, fluorine, copper, boron, bromine, iodine, lithium, manganese, selenium, columbia, molybdenum, germanium, cobalt, vanadium, although mainly in food, but the trace elements in water mostly exist in an ionic state, which is easier to penetrate into cells and be absorbed by the human body. Due to the influence of plant fiber and phytic acid, most of the trace elements in food have an absorption rate of less than 30%, and some are less than 10%. The absorption rate of trace elements dissolved in water is as high as more than 90%, and the amount of water consumed in a day is greater than the amount of food, so the insufficient part must be supplemented by drinking water.

Some people also said: "Lack of minerals and trace elements, I can eat nutrients containing trace elements and minerals to supplement, and it doesn't matter whether there are trace elements or minerals in the water." "We say that nutrition products can supplement people with trace elements and minerals, but the role of trace elements and minerals in water in water is not only the role of nutrients.

An indispensable source of life. -v-

Water is important and an essential ingredient for the human body! If there is no water, people and all living things will die!

Liquid and transparent.

Hee-hee.

Water is something you can't live without it.

Water, with the chemical formula HO, is an inorganic substance composed of two elements, hydrogen and oxygen, which is non-toxic and drinkable. It is a colorless and odorless transparent liquid at room temperature and pressure, and is known as the source of human life. Water is one of the most common substances on the earth, an important resource for the survival of all life, including inorganic chemistry, and the most important component of living organisms.

Water is the most widely present substance on the earth, and lakes, oceans, rivers, and rivers are all composed of water, which is the carrier of aquatic animal survival. It is also the most basic substance for biological survival.

With the presence of water, life is born. Water forms rivers, nourishes crops and trees in river basins, provides habitats for people and animals, and develops civilization.

People and animals living in cloudy areas get drinking water through rainfall and meltwater from icebergs.

Water is a substance in which 2 hydrogen atoms and one oxygen atom are combined in a covalent bond manner to form a relatively stable new molecule.

Water is a substance everywhere in the earth, the sea and rivers flow with water, icebergs are frozen water, the air contains vaporized water, most of the plants contain water, and more than 60% of the human body is water.

The source of human life. Saving water is currently a top priority for humanity. At present, on a distant planet, a water source has been discovered, but far water cannot quench the thirst of the near, and saving water is still the top priority of human beings.

Recently, two groups of astronomers from the California Institute of Technology in the United States worked on the same quasar, and on this distant quasar, they discovered a very large reservoir. Quasars are the brightest and most active objects in the universe, and this reservoir is the largest and most distant source of water ever discovered.

The mass of this large amount of water vapor found by researchers is at least 140 trillion times the mass of the world's oceans, which is equivalent to the mass of 100,000 suns. It's just that the water is farther than the horizon, 30 billion trillion miles away.

Because quasars are so far away, it would take 12 billion years for the light it emits to reach Earth. Therefore, these observations show that the universe is about 1.6 billion years old. The most special thing about this quasar is that it is surrounded by very massive water.

Our observations show that water is ubiquitous throughout the universe, even in the very early days, the researchers say. Findings related to this quasar will be published in the August 2011 issue of the AstrophysicalJournal Letters.

The energy of the quasar is supplied by a huge black hole, which continuously consumes the surrounding gas and dust disk, and is responsible for eating the gas and dust, and the quasar will spew out a large amount of energy. The quasar, called apm082795255, is a large black hole with a mass equal to 20 billion suns and an energy of up to 1,000 trillion suns.

Astronomers had expected water vapor to exist in the early universe, so the discovery of water was not too surprising to them. We also have water vapor in our galaxy, although the total mass is only 1,4000 times that of this quasar, because most of the water in the galaxy is frozen and exists in the form of ice.

The quasar is on the warm side, minus 53 degrees Celsius.

Water vapour is a trace gas and is an important thing to understand the nature of this quasar. In this particular quasar, water vapor is distributed around the black hole in a gaseous state, and the entire area is calculated to be hundreds of light-years wide (1 light-year is about 6 trillion miles). In addition, this water vapor tells us another thing:

If you look at it by astronomical standards, the gas temperature on the quasar side is warmer and the density is higher. Although the gas is quite cold at minus 53 degrees Celsius, and its density is only 1 trillionth of the Earth's atmosphere, it is still 5 times warmer and about 10 to 100 times denser than the average temperature and density of the Milky Way. (The Milky Way is a fairly typical galaxy in the universe.) ）
