Isn t it bad to always drink boiling water? Because there s no oxygen in it!! All stagnant water?

Can you boil the water with boiling water?

Take a small bottle (a small glass or medicine bottle), fill it with some water and place it in a pot of clean water resting on the fire. In order for the vial not to touch the bottom of the pot, the vial should be hung on an iron ring. When the water in the pot boils, it seems that the water in the bottle will also boil.

But no matter how long you wait, you can't wait for this result: the water in the bottle will be hot, very hot, but it will never boil. The boiling water doesn't seem to have enough heat to boil the water.

This may seem like a surprise, but it's also expected. In order to boil water, it is not enough to heat it to 100 degrees Celsius, but also to give it a large part of the heat to change the water from a liquid state to a gaseous state.

Pure water boils at 100 degrees Celsius. No matter how much it is reheated under normal conditions, its temperature will not rise again. That is to say, since the temperature of the heat source we use to heat the water in the bottle is only 100 degrees Celsius, the temperature it can bring to the water in the bottle is only 100 degrees Celsius.

Therefore, by heating the water in the bottle in this way, we cannot get the additional "latent heat" necessary to convert it into steam (water needs about 2,000 joules or more per gram of water to be converted into steam). That's why the water in the vial can't boil no matter how heated it is.

The question may arise: what is the difference between the water in the vial and the water in the pot? You must know that the water in the small bottle is also water, but it is separated by a layer of glass from the water in the pot, why can't the water in the bottle boil as well as the water in the pot?

It's because this layer of glass blocks the water in the bottle and prevents it from convecting with the water in the pot. Every molecule of the water in the pot can come into direct contact with the hot bottom of the pot, while the water in the bottle can only come into contact with the boiling water.

So it is impossible to boil water with boiling pure water. But if you sprinkle a handful of salt into the pot, the situation is different. The boiling point of brine is not 100 degrees Celsius, but slightly higher, so you can boil pure water in a glass bottle.

Please, when you're thirsty, you need to drink water, not oxygen, you don't care if there is oxygen in the water

The purpose of boiling water is to kill germs.

Ha ha! There are still people who ask such stupid questions! ~~

Stirring before drinking boiling water before drinking it will not"Hypoxia"Finish.

Do you have to drink it when you open it?

It's good for the body to drink it when it's cold.

Yes, plain water is the best choice when you are thirsty, you can quench your thirst without worrying about drinking too much nutrients or calories.

The best drink is plain water, don't worry.

Oxygen is not drunk.

Raw water Raw water contains a variety of bacteria, viruses and zoonotic parasites that are harmful to the human body, which can easily cause acute gastroenteritis, viral hepatitis, typhoid fever, dysentery and parasitic infections. Aged water is commonly known as"Backwater", that is, water that has been stored for a long time. Drinking this kind of water often will significantly slow down cell metabolism and affect the growth and development of the body for minors; Middle-aged and elderly people will accelerate aging.

According to medical experts, the incidence of esophageal cancer and gastric cancer is increasing in many places, which may be related to long-term drinking of aging water. Thousand boiling water Thousand boiling water is water that has been boiled on the stove overnight or for a long time, as well as water that has been boiled repeatedly in an electric water heater and water from a steamer that has been used many times. This water is boiled for too long, and the water has a high content of non-volatile substances, such as calcium, magnesium and other heavy metals and nitrite.

Drinking this water for a long time can cause nitrite poisoning. Unboiled water The tap water that people drink is sterilized with chlorine. 13 kinds of harmful substances can be separated from chlorine-treated water, among which halogenated hydrocarbons and chloroform also have carcinogenic and teratogenic effects.

When the water temperature reaches 100 degrees Celsius, these two harmful substances will be greatly reduced with the evaporation of the vapor, and if it continues to boil for 3 minutes, it is safe to drink. Re-boiling water Some people are accustomed to re-boiling the remaining warm boiled water in the thermos before drinking, in order to save water, coal and time. But this kind"Save"Not enough to take.

Because the water is boiled and burned, so that the water evaporates again, it is equal to drinking"A thousand boiling waters"。

It's not beneficial, you said it's stagnant water, do you still need to talk about what is in it?

Generally, there will be no problem, and some people will have diarrhea if they have a bad stomach, so it is better not to drink it.

Aged water: commonly known as "stagnant water", that is, water that has been stored for a long time. Drinking this kind of water often will significantly slow down cell metabolism and affect the growth and development of the body for minors; Middle-aged and elderly people will accelerate aging. The incidence of esophageal cancer and stomach cancer is increasing in many places, and according to medical research, it may be related to long-term drinking of aging water.

The data show that the toxic substances in aged water also increase with the increase of water storage time.

It's not beneficial, you said it's stagnant water, do you still need to talk about what is in it? Adopt it.

Hehe, if a lot of things are answered by science, then you'd better not drink anything, don't eat anything, and wait for death

If a lot of things are answered by science, then you can't live, anyway, everyone drinks buckets of water, and mineral water doesn't see anything, do you?

I don't understand, I don't have any knowledge about this.

But you can choose to drink this group of cute little things alive.666 But there must be bacteria in the water, in your stomach, in your hands, in your mouth, all over your body, including the keyboard xddd you're typing

yes, that's right, that's it.

Bacteria are invisible to the naked eye, and there will be corpses.

That can't be helped, it's better than dying of thirst.

Haha Bacteria belong to microorganisms that do not have corpses.

You eat chickens, ducks, fish, sheep, pigs, and cows every day, and you don't see them, and you feel nauseous.

Is the result the same for a dead worm and a live worm to enter your body?

Boiling water is not stagnant water, and drinking boiling water is better than drinking pure water, because boiling water only kills the bacteria, and there are still a lot of trace elements in boiling water, so there is no need to worry.

It is best to drink the cool white boil after boiling, and it is not good to drink pure water, which is well known. Everything is the closest to nature, and I would rather drink the spring water that comes directly from the ground.

A pool of water is stagnant if it stays there forever, and if it flows, the microorganisms in the water will flow down the water, and if it doesn't, it will accumulate more and more. Do you still think boiling water is stagnant water? It is better to boil the water and drink it.

The so-called "stagnant water" does not mean that you will die if you drink it, don't just take it literally, you don't want to be too nervous.

"Stagnant water" actually means that the water itself has lost its activity, drinking too much has no nutrients at all, and long-term use of such water will lead to the loss of nutrients in the body, and many people's inexplicable hair loss is inseparable from the frequent drinking of inactive "stagnant water".

As for why the water that is continuously heated in the water dispenser is stagnant water, the molecular formula of water is composed of two hydrogen (H) atoms and one oxygen (O) atom, and the structure of water molecules is electrolyzed after continuous high-temperature heating through electricity, resulting in the loss of oxygen in the water, and the loss of oxygen content makes the water lose the effect of supplying sufficient water to the human cells, and the human cells will be difficult to absorb other nutrients if they lose these oxygen-containing substances, so such water is called "stagnant water".

In fact, usually the water for drinking at home can be drunk by filtering and slightly heated to 70 or 80 degrees, and there is no need to let the water be heated to a boiling state and then cooled before drinking. Except for a few areas, the water quality is particularly bad, so more links are needed to deal with it.

I hope you can have a little understanding of water, and I wish you good health! ~

Whether the alternating hot and cold water on the water dispenser is harmful to the body, the most important thing is the quality of the bottled water. If the quality of the bottled water is guaranteed, then there is no big problem with the hot and cold water on the water dispenser. If the quality of the bottled water is not up to par, or the tap water is filtered directly from the water dispenser, then drinking hot and cold water alternately may poison the body.

In this case, cold water is "raw water" that contains a lot of bacteria.

There is also a definition of yin and yang water, one refers to the water after mixing raw water with boiling water, and when the water in the automatic heating water boiler is insufficient, it will automatically add water. At this time, if the person receiving the boiling water does not pay attention or is in a hurry to drink, the electric water boiler will flow out of the yin and yang water.

Note] Yin-Yang water may contain various pathogenic microorganisms, so drinking Yin-Yang water may cause various intestinal infectious diseases.

I use an electric kettle and boil the tap water in 3 minutes.

Water from water dispensers, whether hot or cold, is not good for health. It is recommended to discontinue it as soon as possible. Be sure to!

Not that said.

The quality of bottled water can generally be guaranteed, and it is recommended to drink it for a long time.
