Water is the source of life, no living thing can survive without water, and it can be said that the distribution of water in nature is also very wide, but now people's lives are constantly improving, the way of drinking water is also changing, water will deteriorate in bottles, and it will not deteriorate for billions of years on the earthThis is because the water we pack in bottles is bottled mineral water formed by processing, various processes and sterilization and sterilization to form bottled mineral water, and bottled mineral water will deteriorate if it is placed in a bottle for a long time or after a period of timeIt is because there are bacteria or microorganisms that breed and cause the water quality to deteriorate and the plastic bottle will also produce a certain dissolution or deterioration, making the water quality smelly and poor, and the water in nature is filtered through layers to reach the underground river, so that the water can be directly drunk, although there is a micro life, but it is a kind of original ecology, without treatment or sterilization. <>
Nowadays, we basically drink tap water and drinking mineral water, but these water need to go to a specific place to take water, and then process a series of processes, especially after precipitation treatment and sterilization and disinfection to meet a testing standard, only after reaching this standard can it enter the bottle, and then sterilize and sterilize after sealing and preservation, before it can be ** to the marketHowever, these bottled mineral waters, they will add various mineral elements when sterilizing and sterilizing, and they can only be bottled after sterilizationAfter long-term storage, they will have a certain shelf life, on the one hand, because the water quality will be nourished and multiplied by microorganisms after opening or leaking airOn the other hand, because the bottled mineral water bottles are plastic, these plastics will deteriorate and dissolve after a certain period of time, so that the water quality changes. <>
And water in nature isAfter various evaporation or precipitation into the underground river, it has to go through the action of multiple layers of soil and microorganisms, so the water quality of the precipitation in the underground river is very goodAnd people often yearn for mountain spring water, which is drinkable. On the one hand, because these waters have not been subjected to some sterilization and disinfection treatment, and they have not accelerated special elements and substances are very natural water quality, so they will not deteriorate. <>
Therefore, when we drink bottled mineral water in life, we must drink it quickly within a period of time, or do not store it in some high-calorie or sun-exposed places.

Water is closely related to life on the earth, without water, then the earth would be deserted, without any signs of life, some people say that you can't drink overnight water, which will cause diarrhea, because the water has been infected by microorganisms, and it has expired, so why does the water in the bottle spoil, while the water has not spoiled for billions of years on the earth? In fact, the reason is very simple, the water on the earth will not expire, because the water on the earth is maintaining the water cycle, and the organisms in the water also maintain the cleanliness of the water, which is equivalent to the function of water with self-consciousness, while the water in the bottle does not have the function of self-inspection.
There are some other organisms in the water, such as producers, consumers and decomposers, but most of the producers are plants, which can photosynthesize and purify water resources to make water cleaner and purer. In the water, although there will be some impurities, the organisms present in the water have the function of decomposition, so as to keep the water clean. Moreover, the flow of water on the earth can be continuously purified, and the leaves on the trees falling into the water will also play a role in filtering the dust in the water, which is a natural filter.
Water on Earth is evaporating all the time, and when water vapor rises into the air, it causes rainfall, which falls back on Earth to form new rain. But for bottled water, it is very different, because bottled water is in a static state, there is no water circulation, it is equivalent to stagnant water, and after a long time, some bacteria and other microorganisms will breed.
Moreover, there is no automatic purification function in the bottled water, it will deteriorate after a long time, and microorganisms will grow out when infected with other bacteria, which will "eat, drink, and sleep" in the bottle, and will not be discharged if they are accumulated in the bottle for a long time, which will lead to the water being polluted and spoiled, and people will get sick or have diarrhea when they drink it.
-
Because water is placed on the earth to flow continuously, it is placed in a bottle to isolate oxygen, and the air is closed and does not circulate, so it quickly deteriorates when placed in a bottle.
-
Because if water is placed on the earth, it is living water and flowing, but if it is placed in a bottle, it will become stagnant water, and the microorganisms in it will continue to multiply, which will cause the water to deteriorate.
-
The water placed in the bottle did not run. The water on the earth is in constant flux and therefore does not deteriorate for decades, but the water in the bottle does not flow and therefore has a shelf life.
-
Why does water not deteriorate when it is placed on the earth for billions of years, and it spoils quickly when it is placed in a bottle?
-
Some people say that the water stored on the earth will not expire for hundreds of millions of years, so why does this water expire when it is put in a mineral water bottle? In fact, it is not the water that spoils, but the bottleWhen the bottle is soaked in water, it destroys the protection of the surface for too long, and the layer of water will deteriorate. <>
The simplest and most effective way to preserve water, and the long-term method is to use a glass bottle, use a clean glass bottle to fill a bottle of water, use the traditional wax sealing method, it is best to pump out the oxygen, this bottle of water will not be bad for 10 years, 20 years or even 100 years, as long as the bottle itself will not crack, because the glass itself will hardly penetrate the substance to the outside, but the plastic bottle is not good. If the plastic bottle is left for a long time, the protective layer will be destroyed, and then the water will taste weird when you drink it, with a strong plastic smell. <>
And the water placed in the earth will not be bad, because the water is in a flowing state is a natural state, and it is not a down standard, the water in the bottle will be broken, and it is not that the water is really bad, the water is still put in nature, after a long time of natural precipitation and purification, this water can still be drunk, but this water can not meet the drinking standard now, it may contain some harmful substances to the human body, this water can not be drunk. Therefore, it is called water deterioration, but in fact there is no essential change, but according to the standards of human drinking water, it is not allowed. <>
The water on the earth is recycled, the water will not come out naturally, it should be said that the total amount of water resources on the whole earth is fixed, so the water we drink may be the sewage that people discharged into the earth decades ago and hundreds of years ago, after the natural evolution and precipitation of the earth for a long time, people are now mining the water, and then purifying it into a bottle after their own processing, we can drink this water. This water is purified, and it is naturally drinkable, but it cannot be drunk all the time, and it will return to the standard of not being drinkable after a long time.
-
The water in the bottle does not expire, and the expiration date is mainly for the bottle itself. The bottle is soaked in water, and the protection of the surface is destroyed for too long, which will lead to water pollution, so there is a saying that there is a shelf life in the bottle, and the main prevention is the bottle rather than the water.
-
It is because the water on Earth is fluid. Water can easily spoil or become moldy when left in a bottle. The standards of the two types of water are completely different.
-
Because of the self-cleaning ability of water, the reason why the water on the earth does not expire is because the water on the earth is constantly in the water cycle, and the organisms in the water are also maintaining the cleanliness of the water, which is why we say that "water has the ability to clean itself".
We know that there are so many organisms in water that can be broadly divided into three categories according to their species: producers, consumers, and decomposers. The producers are mostly plants and can produce energy through photosynthesis.
Most consumers are animals, and they cannot generate energy themselves, so they need to obtain energy from the outside world. Decomposers are mostly microorganisms that break down organic matter into simple inorganic matter.
In addition to its self-cleaning ability, water also participates in the water cycle. Water on Earth evaporates all the time, and after evaporation, the water vapor is relatively light and rises to the sky. When enough water vapor accumulates in the air, the water vapor will condense with dust and particles to form small water droplets, which will fall downward, but because the diameter is small enough, they will evaporate again on the way down.
Only small water droplets with a larger diameter will drip onto the ground, forming rainwater.
In addition to the atmospheric water cycle, Nature has also reported that the Earth's interior is also undergoing a water cycle. There is a trench near Japan, the deepest known trench in the world: the Mali-Gana Trench.
The Marigana Trench is located at the subduction boundary, where seawater enters the Earth's interior, into which hundreds of millions of tonnes are swallowed every year. However, the swallowed seawater will also flow to the surface along the volcanic eruption, completing the water cycle.
In fact, the drinking water in the bottle also comes from the water in rivers and lakes, but these water belongs to the "raw water", and it also needs to go through a series of processes such as precipitation, impurity removal, disinfection, filtration and so on to clean up the impurities in the raw water, and it will be injected into the bottle after testing to meet the human drinking water standards. The water in the bottle is a closed system compared to rivers, lakes and seas, and only some microorganisms can survive in this system, which also makes microorganisms have no natural enemies to multiply in large numbers. Although the bottle is sealed and preserved, the microorganisms are very small, and many microorganisms are vegetatively reproduced, and the reproduction time is relatively short, from one microorganism to thousands of microorganisms in just 6 hours.
Because of this, over time, the number of microorganisms in the bottle will surge, and it will no longer be suitable for human consumption, so mineral or purified water will generally have a shelf life.
-
Because water is limited in space if it is bottled, it is easy to spoil, but it is a natural environment on the earth, so it will not spoil for a long time.
-
Because the air on Earth is circulating. And inside the bottle is a confined space. It changes in a confined space, so it deteriorates.
-
Because the water on the earth can be constantly recycled, microorganisms can maintain the cleanliness of the water, and the water has the ability to clean itself.
-
Water in nature is in constant flow and circulation. This kind of water changes between the three states of solid, liquid and gas, and in the process of continuous circulation, the water will go through a series of physical and chemical actions, so as to obtain the effect of purifying water quality. The ancient saying "flowing water does not rot" is exactly this principle.
Although bottled water will go through purification, disinfection and sterilization processes during the production process, it is not completely guaranteed that it does not contain any organic substances, even if a small organic matter is decomposed and released into the water, and the bottled water container is small, immobile and does not have the ability to self-purify, and the water quality will naturally deteriorate.
-
What does not deteriorate is living water, flowing, to the bottle is stagnant water, after seeing the wild survival, the wild living water can be drunk.

Water, common and mysterious, existed on the earth hundreds of millions of years ago, and it is because of its existence that life is possible. It is an important resource for the survival of all life, including human beings, and is also the most important component of living organisms.
Water has been around for so many years and has always remained vibrant, but when you see the expiration date of bottled water in the supermarket, you can't help but wonder:
Water that has existed on the earth for hundreds of millions of years will not spoil, why does it expire when it is bottled?
The reason why water on earth has no shelf life is mainly because of the important role that nature plays in it. Water on Earth is always in flux and circulation. In this process, the earth is like a large water purifier.
We know that the various forms of water on the earth's surface are constantly transforming into each other, and the process of continuous circulation of water between land, sea and atmosphere in gaseous, liquid and solid forms is the water cycle. Base precipitation, evaporation, and runoff are the three most important links in the water cycle, in which water is purified to a certain extent.
For example, runoff, especially underground runoff, water bodies will encounter a lot of stone crevices and sand in the process of flowing underground, and these stone crevices and sand play a role in filtering the water.
Therefore, as long as the water cycle exists, the water on the earth will not deteriorate.
So why does water in bottles have an expiration date?
The bottled water we see in the supermarket is purified and the packaging is sterilized, so it will not spoil for a long time. But as soon as we open it, bacteria will take advantage of it, continue to multiply in the water, accelerate the deterioration of the water, usually we do not recommend continuing to drink a bottle of bottled water for a day or two after opening.
This is mainly because the water in the bottle no longer participates in the natural water cycle, so there is no self-purification ability, usually a basin of water at home for a long time, bacteria and microorganisms continue to breed, it will be easy to smell, it will deteriorate.
In general, the expiration of water is actually a deterioration, and if it is allowed to re-participate in the water cycle, it can return to its original state. However, although water has the ability to purify itself, it takes a long process, so we still have the responsibility and obligation to reduce water pollution and protect water resources!
Because the vertical stability of the earth's gravity is generally recognized in our daily life, the earth's natural force, that is, the earth's gravity, is commonly known as the "earth's fixed gravity" (also to distinguish particle microgravity). The theory of studying the meaning, function, laws and characteristics of "the earth's natural force, that is, the earth's fixed gravity", is the "earth's fixed gravity", referred to as "the earth's gravity", which is the earth's natural force generated by the earth's material mass as a whole, that is, the earth's gravity, which occurs in and to the center of the sphere, also known as the spherical gravity. The natural force of the earth, that is, the energy of the earth's body (earth) and the earth's outer space (sky) reached by the earth's gravitational force, condenses in the direction of the earth's core, and this cohesion is carried out in a vertical downward way to stabilize the energy of the things it reaches. >>>More
Because the earth is the only planet with life, and water is the source of life.
The ocean covers 71 of the Earth's surface, and if all the water in the ocean were evenly spread on the Earth's surface, a 2,700-meter-thick hydrosphere would form on the Earth's surface. So some people say that the name of the earth is wrong, and it should be called "water ball". From the origin of life on earth to the formation of human society, from a primitive society with low productivity to a modern society with advanced science and technology, man and water have formed an indissoluble bond. >>>More
At the current level of detection, it is simply impossible to actively detect aliens.
Talk about entertainment: According to Genesis 11 in the Bible, the Tower of Babel was built by mankind in the hope of leading to heaven. In order to stop the human plan, God made the human beings speak different languages, so that the human beings could not communicate with each other, and the plan failed, and the human beings scattered from then on. >>>More
