What is the best degree of water to boil? The water can be drunk at as many degrees as it boils

Everyone knows that drinking more boiled water in daily life is good for health, but how to boil water and how to drink boiled water are still a lot of attention.

Boiling water can kill bacteria and remove substances harmful to the human body, because tap water is chlorinated, and chlorine interacts with residual organic matter in the water to form toxic carcinogenic compounds such as halogenated hydrocarbons and chloroform. When the water temperature reaches 90, the content of halogenated hydrocarbons rises to 191 micrograms, and chloroform rises to 177 micrograms, both exceeding the national standard by 2 times. When the water temperature reached 100, the levels of halogenated hydrocarbons and chloroform were 110 micrograms and 99 micrograms per liter, respectively. If you continue to boil for 3 minutes, the two substances quickly drop to micrograms and micrograms per liter, respectively, to meet the drinking standard. Therefore, it is best to boil water for about 3 minutes.

In order to save water, some people often reheat the leftover boiled water, which is a bad habit. Because repeated boiling of water will cause the aging of water, it will not only cause the loss of minerals that are beneficial to the human body, but also may produce some harmful substances such as nitrite. Once nitrite enters the human body in large quantities, it can make the red blood cells in the blood lose the function of carrying oxygen, resulting in tissue hypoxia, people will drink this water for a long time will cause nausea, vomiting, headache, nails and lips purple, palpitation and other symptoms, serious can also cause hypoxia, and may even induce cancer.

After getting up in the morning, drink a cup of cold and white, which is good for health. Many people like to dry a glass of boiling water the night before and drink it again the next morning. This is okay when the temperature is not high; For example, in summer, when the temperature exceeds 30 degrees Celsius, the air humidity is high, and the bacteria multiply quickly, the cold boiled water overnight will lose its biological activity, and it is very easy to be contaminated and cause diarrhea.

You can pour half a small cup of boiled water the night before, then cover the lid, and mix the boiling water with warm water the next morning.

In addition, the time of cooling and boiling should not be too long, and the boiling water boiled on the same day is best drunk on the same day. It is best not to drink it again if it is left cool for more than 3 days

More than 80 is fine, don't burn much.

Generally, you can drink it when the water is boiled to more than 80 degrees, but it is recommended to burn it to 100 degrees.

If the water is filtered by a water purifier or bottled water, it can be drunk when it is boiled to 85 degrees, because the water that has passed through the water purifier has been filtered into pure water. If it is tap water, then it is recommended to boil until it is boiling before drinking. Water is one of the most common substances on earth, an important resource for the survival of all life, including inorganic compounds, and the most important component of living organisms.

1. How many degrees should the water be boiled before drinking.

1.From the point of view of simply drinking water, water can be drunk as long as it is boiled to 80°C or more.

2.From the perspective of sterilization, the higher the temperature, the better the sterilization effect, so it is generally burned to 100°.

2. What is the correct way to boil water.

1.The water should be thoroughly boiled before drinking, can not see the water surface has waves or large bubbles produced, it is considered to have boiled, this return to the time of the bacteria in the water has not completely volatilized, so the toxicity of the water is relatively large, we have to wait for the water to boil and then burn for a period of time before drinking.

2.The boiling time should not be too long, and the same pot of water should not be boiled repeatedly, because boiling water for too long or repeatedly boiling water may lead to the production of nitrite and other harmful substances in the water. Therefore, try to control the boiling time to about five to ten minutes.

The water can be boiled up to degrees.

When boiling water, it converts from a liquid state to a vapor (gaseous state) as the temperature increases. If the pressure does not rise, no matter how much you boil, the water will not exceed 100 until it evaporates. However, if water is boiled in a closed situation, such as with a domestic pressure cooker sealed, water vapor has nowhere to excrete and will accumulate in the pot.

As more and more vapors are generated, the sealed vapors accumulate more and more in the pot, and the density increases, which leads to the squeezing of the water body, so that the pressure on the water body will increase, and the temperature of the boiling point (phase becomes vapor) will be higher and higher.

But there will be a tipping point for the increase in water temperature, which will not reach 1000.

From the relationship between pressure and boiling point, the higher the pressure, the higher the boiling point temperature and hence the higher the water temperature. That is to say, the higher the pressure, the higher the water temperature, and the water temperature is directly proportional to the pressure. But does the water temperature rise linearly as the pressure increases?

Theoretical and experimental evidence proves that it will not. Because when a pressure critical point is reached, the density of water vapor and the density of water will be the same, so that the temperature will never rise again.

This critical point is at 225 atmospheres, and when you reach this pressure, the water temperature can reach degrees, and after that, the pressure is rising, and the temperature cannot rise. This degree of water (or water vapor) is called supercritical water. After reaching this critical point, the pressure rises again, and the water temperature does not rise.

The water can be boiled up to 374 degrees. At standard atmospheric pressure, the temperature at which water boils is about 100 degrees, and as the pressure increases, the temperature at which the water boils will also increase, but the maximum temperature of water is about 374 degrees, and when the water reaches this temperature, the pressure will increase and gasification will occur.

The boiling point of water is related to pressure, the higher the pressure, the higher the boiling point, but the critical temperature of water is 374 degrees.

Water is an inorganic substance composed of hydrogen and oxygen, which is a colorless and odorless transparent liquid at room temperature and pressure.

At standard atmospheric pressure, pure water has a boiling point of 100 and a freezing point of 0.
