Boil water in an aluminum kettle, after boiling, can you drink it without pouring it cold?

Can you drink it, is this cold and white, but you can't leave it for too long, and after more than 12 hours, don't drink it.

A recent study by researchers from Harbin Medical University revealed that boiling water in different containers has obvious changes in the chemical composition of water such as aluminum. The researchers boiled water in glass containers and aluminum containers, and then measured them in accordance with the national standards for drinking water, and found that after the tap water was boiled, nitrite nitrogen, ammonia nitrogen and other indicators changed, most of the values were super high, but the range of changes generally did not exceed the range allowed by the health standards, and the water quality of the water boiled in aluminum kettles was larger than that produced by glass containers, and the values were higher. Studies have found that large amounts of aluminum are produced in water boiled in aluminum kettles, and the content of aluminum is high when the water is boiled.

Although aluminum has not been officially included in China's drinking water sanitation standards, its health hazards, especially the impact of brain cells on aging, have been recognized by the academic community. The World Health Organization and Chinese scholars believe that the content of aluminum in drinking water should not be exceeded. Experts point out that there is a difference in the amount of aluminum dissolved between the old and new aluminum kettles, but even with the old kettle, the aluminium in the water is much higher than the allowable content.

They suggested that it is best for Malaysians to switch to boiling water with glass facial appliances to reduce the risk of excessive intake of aluminium in the body.

It is good to hold boiling water in an aluminum pot, because it has a very strong thermal conductivity, but it is necessary to avoid contact with acidic liquids, so as not to erode the oxide layer, at this time, the aluminum will melt into it when it comes into direct contact with water, which is harmful to people's health.

In life, many of the kettles we boil water are made of aluminum, which has a very strong thermal conductivity and can heat cold water well, but generally speaking, aluminum itself is very soft, and it needs to be chemically reacted with manganese and other metal elements to form aluminum alloy, so that it is easy to use.

At room temperature, aluminum is easy to oxidize, but alumina is not harmful to the human body, that is to say, as long as there is a layer of oxide on its surface, it is very safe to dismantle and imitate, so it can be used to fill hot water, it should be noted that you must not use an aluminum pot to contain acidic liquid, which will lead to the erosion of the oxide layer, so that the aluminum in it is directly in contact with the liquid travel slimming body, it will be integrated into the liquid, and drinking this water will also be harmful to the body.

To a large extent, there is not much difference between aluminum and aluminum alloy, so as long as it is filled with water, and the oxide layer inside the aluminum pot will not be destroyed, it will basically not cause harm to the human body, but the water to be drunk cannot be put in the aluminum pot for a long time, especially overnight.

Summary. Dear, we are glad to serve you, the answer is as follows: The melting point of aluminum is Celsius, and the maximum temperature at which water boils is 100 degrees Celsius under standard atmospheric pressure, which is much less than the temperature required for aluminum to melt, so the aluminum kettle will not melt when boiling water. The temperature keeps the boiling point temperature unchanged, the boiling point of water under standard air pressure is 100, so as long as there is water in the pot, the temperature will not exceed 100, and the melting point of aluminum is 660, and the temperature of water cannot reach the melting point of aluminum.

Dear, I am glad to serve you, the answer is as follows: The melting point of aluminum is Celsius, and the maximum digging temperature of water boiling is 100 degrees Celsius under standard atmospheric pressure, which is much less than the temperature required for aluminum to melt, so the aluminum kettle will not melt when boiling water. The temperature keeps the boiling point temperature unchanged, and the boiling point of water under standard air pressure is 100, so as long as there is water in the dust pot, the temperature of Hunger Dispersion Zen will not exceed 100, and the melting point of aluminum is 660, and the temperature of water cannot reach the melting point of aluminum.

The aluminum kettle boiled for 3 hours.

No questions answered.

Answer: Because the melting point of aluminum is Celsius, under the standard atmospheric pressure, the maximum temperature at which water is boiled is 100 degrees Celsius, which is far less than the temperature required for the rapid melting of the aluminum mold, so the aluminum kettle will not melt when boiling water. The temperature keeps the boiling point temperature unchanged, and the boiling point of water under air pressure is 100, so as long as there is water in the pot, the temperature will not exceed 100, and the melting point of aluminum is 660, and the temperature of water cannot reach the melting point of aluminum.

Because it has a melting point of 660°, you won't have a melting point, so it will burn.

After boiling dry, there is no water and continue to boil.

Because the temperature reaches 100 and will not continue to rise.

His melting point of 660° 100° is 560° less

When the water is dry, continue to boil the kettle and keep it at 100 degrees.

Yes, dear. Oh, got it.

Uh-huh. The kettle has the same 100 degrees for both water and no water.

Yes, because that device reached his apex.

When you reach the apex, you won't keep adding.

1. Aging water: commonly known as "stagnant water", that is, water that has been stored for a long time.

2. Thousands of boiling water: Thousands of boiling water is water that has been boiled on the stove overnight or for a long time, and water that has been boiled repeatedly in an electric water heater. This kind of water is boiled for too long, and the water has a high content of non-volatile substances, such as calcium, magnesium and other heavy metal components and nitrite.

Drinking this water for a long time will interfere with people's gastrointestinal function, causing temporary diarrhea and bloating; Toxic nitrites can also cause the body to lack oxygen.

3. Steamer water: Steamer water is leftover pot water such as steamed buns, especially the steamer water that has been used repeatedly for many times, and the nitrite concentration is very high.

4. Unboiled water: The tap water that people drink is treated by chlorination and sterilization. 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.

5. Re-boiling water: Some people are accustomed to re-boiling the remaining warm boiled water in the thermos before drinking, the purpose is to save water, coal (gas) and time. , but this "saving" is not enough.

Because the water is boiled and burned, the water evaporates again, and the nitrite will rise, and if you drink this water often, the nitrite will accumulate in the body and cause poisoning.

No, because water reacts easily with CO2 in the air to form acids, and acids easily react with aluminum to form metal solutions, which are harmful to the human body.

It's best not to boil water made by Lu, because Lu ions are not good.

1- The reaction of the aluminum surface with oxygen in the air forms a dense oxide film, which prevents the reaction from proceeding further; 2- Unreasonable; 3- Doing so is easy to damage the aluminum pot, and may also cause the aluminum element to dissolve into the food, thereby harming human health [Test Question Analysis].

When the aluminum kettle is heated, the temperature rises, because when it is filled with water, after the water temperature reaches the boiling point, the temperature will no longer rise, and the temperature of the aluminum kettle is only slightly higher than the boiling point of water, and the melting point of aluminum is not reached, so the aluminum kettle will not be burned out;

If the aluminum pot is not filled with water, the temperature of the aluminum pot will rise until it is close to the temperature of the flame, and if the melting point of the aluminum is exceeded, the aluminum pot will melt, which will cause a fire in serious cases

Take an aluminum kettle, boil a kettle of boiling water, and when the water is boiling, lift the kettle off the stove and gently place the bottom of the kettle on your other hand. You will find that this hand can hold up the entire teapot without feeling that it is only hot. It's the blisters at work.

It turned out that there was a layer of tiny blisters crawling on the bottom wall of the freshly boiled pot. It has good thermal insulation performance, when the bottom of the pot is supported by hand, the heat capacity of the aluminum at the bottom of the pot is smaller, and it quickly balances with the temperature of the hand, while the heat of the water in the pot is insulated by the transporter in a layer of bubbles, so that the hands do not feel hot.
