How long does it take for water to boil and how long does it take to boil water

After boiling water at 100°.

Drive for another 5 minutes, which should be the best at this time.

To explain: the water may contain a small number of microorganisms and need to be boiled for a little longer.

It depends! Generally, a pot of water is OK for ten minutes.

It depends on the amount of water and the size of the fire, the more water, the smaller the fire, the longer the water will boil, and vice versa.

This depends on whether the fire is big or not, and it will open when it all boils!

Depending on how much water you boil, that small electric kettle will be OK in about 10 minutes.

It depends on how well you turn on the fire and how much water you burn. Generally, it burns until it bubbles are bubbling and it's almost there!

The time is different, you can listen to the sound first, and when you hear the sound of rolling, if you are right, it is boiling, and then see if the water is tumbling, yes, it is open, bubbling is not necessarily open, hehe.

It depends on how much water you boil, how big the fire is, just say that it is bubbling and it will be opened.

Look at you boiling it with sprinklers, usually the water doesn't make a sound when it boils.

Theoretically, there is no real boiling water.

Let's see if there is a sound, there was a loud sound before it was opened, and if it really boiled, there would be no sound, and it would roll there.

How much water does it depend on? Ha ha...

Just look at the bubbling gas, the fire is not the same, and the time is not the same.

It depends on the amount of water and the size of the fire

It depends on how big the fire is and how much water there is.

The boiling time of boiling water is better to control within 5-10 minutes.

When the temperature just reaches 100, the content of halogenated hydrocarbons and other harmful substances in the water exceeds the national standard; After 3 minutes of boiling, the content of harmful substances is rapidly reduced to the standard range. If the water is boiled continuously, the amount of halogenated hydrocarbons will decrease. However, there is also an increase in other non-volatile substances in the water, which can also cause harm to the human body.

Therefore, the correct way to boil water is to turn off the high heat as soon as the water is boiling and continue to heat it over low heat. After boiling for 3 minutes, turn it off again and remove a pot of fresh, high-quality purified water.

Precautions for boiling tap water:

It is also necessary to pay attention to boiling tap water, which has accumulated more fluoride in the tap water after waking up in the morning and overnight, which is a component of the disinfectant of the waterworks and is harmful to the human body. Therefore, when you first get up in the morning, it is best to put the tap water first, take out a bucket of water for cleaning, and then use the water to boil water to drink, it will be much safer.

When the water is boiling, the lid of the kettle should be opened and boiled for another two or three minutes to allow these substances to volatilize to the maximum. On the other hand, boiling water for too long will also cause the water to deteriorate and form harmful substances. Therefore, healthy water that meets the needs of the human body should be fresh, and the boiling time should not be too long.

It usually takes about 5-10 minutes for water to boil. Take the kettle used in daily life as an example, it generally takes 5-10 minutes to boil cold tap water, if the water itself has a certain temperature, then the water boiling time will be shorter, and the lid can be opened after the water is boiled, so that the harmful substances in the water can evaporate through the vapor.

Can you drink water overnight.

Overnight water is drinkable because boiled water contains less microorganisms and the quality of the water does not change much even after one night.

As long as the water is placed in a hygienic environment, the water quality is clean, and there are no impurities, dust and other pollutants in the water, it can be drunk.

Although there are very few microorganisms in freshly boiled water, the more microorganisms can be found in the water as it is left out for a long time.

The specific time it can be turned on depends on the amount of water, air temperature, air pressure, and the size of the fire. At lower altitudes, it generally takes 5 to 10 minutes for the water to boil. At high altitudes, it only takes about 3 minutes. <

At low altitudes, it takes 5 to 10 minutes for the water to boil. At high altitudes, it only takes about 3 minutes. The specific time it can be turned on depends on the amount of water, air temperature, air pressure, and the size of the fire.

The hardness of water, i.e., water alkali and scale, refers to all salts such as calcium, magnesium, iron, aluminum, manganese and all salts such as bicarbonate, chloride, sulfate and nitrate, and contains harmful substances such as mercury, cadmium, lead and arsenic.

The hardness of drinking water has a certain impact on human health. According to relevant studies at home and abroad, the higher the hardness of drinking water, the higher the incidence of hypertensive heart disease, coronary heart disease, cerebrovascular disease and kidney stones. With the extension of boiling time, the hardness of drinking water decreases, and if the hardness drops by 50, it needs to be boiled for about 10 minutes.

Boiling water is poured into the cup and placed for 1 hour, the hardness of the cap is more than that of the non-cap, the hardness of the cap decreases more than that of the cap, and the hardness decreases significantly after 1 minute to 1 hour. Therefore, in order to kill the bacteria and viruses in the water to the greatest extent, and to reduce the hardness and nitrite content of drinking water as much as possible, it is better to boil the water within 5 to 10 minutes.

The length of time you are asking about is roughly determined by the following conditions.

1。The amount of water to be prepared for boiling. All other things being equal, the more water you have, the longer it will take to boil.

2。The thermal conductivity and uniformity of the material of the container for boiling water. Containers with good thermal conductivity and uniform material can reduce the time it takes to boil the water in them,3. Prepare the ingredients of the water to be boiled. Generally, tap water or purified water is used for boiling water at home, and under certain conditions, purified water is boiled faster than incoming water.

4。The size and temperature of the fire in which the water is boiled. All other things being equal, the larger the fire and the hotter part of the flame is, of course, faster than the low heat and the lower part of the flame, and the easier it is for the water to boil.

5。The magnitude of atmospheric pressure. Other things being equal, the greater the atmospheric pressure, the more difficult it is for the water to boil. On the contrary, the smaller the easier it is to boil, and the purified water is heated to 100 degrees at standard atmospheric pressure.

6。Prepare the water used for boiling at the ** temperature before boiling. Other things being equal, the higher the temperature of the original water, the shorter the boiling time.

7。Ambient temperature. Other things being equal, you boil water at -30 and 30 respectively, and you can imagine which one is boiled first!

8。Whether to add a lid or not. Adding a lid can prevent the heat of the boiling water from escaping to a certain extent, and make it reach a boiling state faster.

How many minutes does it take for the water to cook, depending on what is being cooked? Some may take eight minutes, some may be half an hour, or even an hour, or even an hour to cook, and you can't generalize.

Three to five minutes after boiling, I am like this, in the plains,
