Why is it that being scalded by water vapor at 100 degrees Celsius is often worse than on water at 1

This is because when you are burned by water vapor at 100 degrees Celsius, the water vapor turns into liquid water (still 100 degrees Celsius), and a large amount of heat (heat of vaporization of water) ...... is releasedSo it's worse than being scalded by water at 100 degrees Celsius.

You can imagine that water from liquid to gaseous state has to absorb heat, although the temperature does not rise, but the energy increases, so 100 degrees Celsius water vapor scalding will be worse than 100 degrees Celsius water.

Hehe, I've learned it before!

Because the water vapor will liquefy into water droplets when it encounters cold **, and the process of liquefaction will release heat, so it ......

Absolutely!

Water vapor at 100 degrees Celsius contains more heat than water at 100 degrees Celsius (0 for heat absorption from water to water vapor).

**14 methods of scalding.

Scalded ** one:

Rinse the wound with cool water first, and then soak the wound in cold water for half an hour. Generally speaking, the earlier the soaking time, the lower the water temperature (not lower than 5 to avoid frostbite), the better the effect. However, if the wound has been blistered and broken, it should not be soaked to prevent infection.

Scalded ** two:

Gently apply light salt water to the burned area to reduce inflammation.

Scalded ** three:

On the injured area, rubbing soy sauce or honey, lard, dog fat, and ginger juice can all be effective.

Scalded ** four:

Use egg white, cooked honey or sesame oil, mix and apply to the injured area, which has anti-inflammatory and pain-relieving effects.

Scalded ** Five:

Cut a few slices of raw pears and stick them to the burned area, which has an astringent and pain-relieving effect.

Scalded ** six:

After the child is burned, boil 25 grams of black beans with water and thick juice, and apply to the wound, which is curative.

Scalded ** seven:

For mild burns, the dried waste tea residue can be roasted on the fire and slightly charred, mixed with vegetable oil to form a paste, and applied to the wound, which can reduce swelling and relieve pain.

Scalded ** eight:

After the hand and foot ** burn, immediately pour the alcohol into the basin or barrel, and soak all the wounds in the alcohol, which can relieve pain and redness and prevent blistering. If soaked for 1 2 hours, the scalded ** can gradually return to normal.

If the wound is not in the part that is easy to soak, you can use a piece of cotton wool to soak in liquor, take it out and apply it to the wound, and pour the wine on the cotton wool at any time to prevent drying. Good results can also be received after a few hours.

Scalded ** nine:

**After being scalded by oil or boiling water, you can use wind oil essence, kaleidohua oil or vegetable oil (such as sesame oil) to apply directly to the injured surface, **If it is not broken, it can generally be relieved in 5 minutes.

Scalded **ten:

Chlortetracycline eye ointment is applied to the wound, and after a few minutes, the swelling and pain can be relieved.

Scalded **eleven:

Apply some soap immediately after the burn to temporarily reduce swelling and relieve pain.

Scalded **Twelve:

Immediately after a mild burn, soak the injured area in kerosene to relieve pain, reduce swelling and prevent blistering.

Scalded ** Thirteen:

1 soft-shelled turtle shell, burnt ash or add a little borneol to grind finely, mix with sesame oil, apply to the injured face, 3 times a day.

Burn ** of Fourteen:

In the event of a small burn, apply toothpaste immediately to relieve pain and suppress blisters. The blisters that have formed will also subside on their own and are less susceptible to infection. Small second-degree burns heal after 1 attempt.

This is because water vapor emits a lot of heat when it vaporizes into water vapor.

From a physical point of view, it's just as hot.

In physics, a physical quantity can be used to reflect whether it is hot or not. This physical quantity is temperature. Simply put, temperature is a reflection of how hot and cold an object is.

High-temperature objects are hotter than low-temperature objects. In this way, water at 100 degrees Celsius should be as hot as water vapor at 100 degrees Celsius.

Ironing is not actually a scientific concept, in the science of weights and balances, temperature can be used to measure heat, but there is no physical quantity to measure ironing. Literally, ironing is actually more concerned about people's feelings, because ironing can reflect the harm that high temperatures of objects can cause to people.

Being scalded by 100 water vapor is more serious than being scalded by 100 boiling water because 100 water vapor will liquefy when it encounters a relatively low temperature of the human body, and liquefaction will release a lot of heat, so 100 water vapor scalds are more severe.

In daily life, it is easy to get burned by water vapor, such as accidentally being burned by the water vapor coming out of the lid of the cooking pot. After the occurrence of the burn, it is necessary to cool the scald in time to prevent the residual heat of the steam from causing further damage to the deep tissues of the skin, and the cooling of the skin will also help to alleviate the pain. In addition, it is necessary to do some emergency treatment to minimize the damage.

When the 100-degree water vapor is burned on the hand, the hand will be scalded once, and then, the water vapor hail on the surface of the hand will be cold and heated, and the water vapor on the hand will turn into liquid water and be scalded again. In other words, if you are burned by water vapor at 100 degrees, you will be scalded twice. Therefore, water vapor at 100 degrees is more severe than water scalding at 100 degrees.

There is a lot of heat absorbed from water to water vapor, and these heat are much more than ice to water).

One kilogram of water vapor at 100 degrees Celsius becomes water at 100 degrees Celsius, and heat is released, which is called the heat of liquefaction of water vapor.

So 100 degrees of water vapor is more hot than 100 degrees of boiling water.

Because 1, the water vapor itself is 100 degrees into water and the liquefaction of the gas needs to be exothermic, so it will cause more damage.

2. The gas flows better and comes into contact with the body faster.

Because when 100 water vapor meets the panel, it first liquefies into 100 water, and then continues to cool and release heat from 100 water. Since a large amount of heat is released during the previous liquefaction process, it is worse than being scalded by 100 meters of water.

When the 100 degree water vapor is burned on the hand, the hand is scalded once, and then, the water vapor attached to the surface of the hand is cold and heated, and the water vapor on the hand becomes liquid water again, and it is scalded again. In other words, if you are burned by water vapor at 100 degrees, you will be scalded twice. Therefore, water vapor at 100 degrees is more severe than water scalding at 100 degrees.

There is a lot of heat absorbed from water to water vapor, and these heat are much more than ice to water).

The condensation of steam into water is exothermic, so it is more likely to burn.

Since it's all 100 degrees, of course the temperature is the same, well, it's all 100 degrees, and no one is higher than the other.

Just like a 100 yuan note and a 100 yuan coin, they are both 100 yuan.

However, if I want to get burned by these two things, I'd rather choose water (the one that is full).

Because it is also 100 degrees, water vapor contains more energy. When 100 degrees of water vapor condenses into 100 degrees of water, a large amount of additional heat energy is released.

Just like a 100 yuan coin is heavier than a 100 yuan note, both are 100 yuan, and the quality is different.

It's all 100 degrees, not because the temperature is high, but when the water vapor condenses, it will release a lot of heat, which is more heat than 100 degrees of water, so it is easier to burn people, and it may be hotter in comparison!

Because at room temperature, 100 degrees of water vapor will quickly liquefy, and liquefaction will be exothermic. So 100 degrees of water vapor scalds more than 100 degrees of water.

Water must absorb heat to become steam, this is the principle of evaporation, when the water becomes steam, the absorption of Nagai is greater than the water at the same temperature, when the steam is out of the water container, it will condense, at this time it has to release heat, relative to the same temperature of the water to release more heat, so the feeling of people is to be hotter than water.

To be exact, ...Water vapor liquefies into small water droplets when cold, and the liquefaction process needs to be exothermic, so the heat released is much higher than 100 degrees Celsius. Opposite. Water at 100 degrees Celsius is vaporized. The vaporization process requires endothermy.

At a standard atmospheric pressure, the minimum temperature of water vapor is 100 degrees. At 100 degrees Celsius, if the heat is continued to be released, it will begin to condense into liquid water. If it is above 100 degrees, it can be achieved by any number of degrees.

The maximum temperature of water vapor can well exceed 384°C. The superheated steam used in the Binaishanru thermal power plant is around 800°C, because the water vapor itself is a gas.

The real water vapor is colorless and transparent, and the white water vapor we see is not water vapor, it is a water mist formed by the liquefaction of water vapor when it is cold. Steam scalding is often severe, and it is basically red when it is scalded by hot water, or there is a little chickenpox.

100 degrees of water vapor traces of dust can not only burn people, but also hurt more seriously, when the steam condenses into water, it will burn the human body again, and Zhou Senyi my point of view thank you.

Water vapor turning into a liquid releases a lot of heat.

Usually, the boiling point of water is only 100 degrees, no matter how boiling the water is, it is only 100 degrees, and it will not exceed 100 degrees, and the temperature of water vapor can reach several times, which is several times higher than that of boiling water, so the scalding of water vapor will be more serious.

Water vapor needs to release a certain amount of heat to turn into liquid, so after the water vapor reaches the human body, if there is a burn, the actual temperature may be higher than 100. Water vapor burns may cause local burns and pain, as well as redness, swelling and inflammation. If there is a phenomenon of water vapor scalding, you should go to the hospital for examination in time.

1.It is true that the water vapor is serious, because the water vapor will be exothermic as it becomes water, and then the water at 100 degrees will continue to burn. It's equivalent to one more perm.

2.The temperature does not change during the process of water vapor turning into water because the heat released reduces the potential energy of the molecule (the kinetic energy of the molecule does not change when the temperature does not change), so the energy is also conserved.

Because heat is released during the liquefaction of water vapor into water, the temperature of 100 degrees Celsius is maintained for a period of time. This is similar to an ice-water mixture, even though the ice has turned into water, the mixture is always 0 degrees Celsius.

Kindness... Anyway, that's how ... As for my expression, it may be biased, so I'm sorry

Although the temperature is the same, the energy contained in water vapor is high, and the energy contained in water is not all determined by temperature, as well as state, pressure, etc., for example, two people of the same weight punch you, one is a muscular man, the other is a fat man, although the weight is the same, but it is definitely a muscular man who hits you more.

The temperature will change after liquefaction.

It is water vapor severely.

What he meant was that 100 degrees of steam liquefied to 100 degrees of water would release a lot of heat. Let me give you an example. 1 ton of 100 degree saturated steam can be heated to 100 degrees by 5 tons of 0 degree water, so the enthalpy of steam (you can understand the heat) of the same mass of water and steam must be 5 times larger than water.

Water vapor is severe.

Because after being scalded by water vapor, the water vapor liquefies when cold and is exothermic.

It became 100 degrees Celsius water.

The water is then exothermic. You say that's serious?

Water vapor scalding at 100 degrees Celsius is more serious, because water vapor liquefaction releases heat when it encounters the human body, which makes the temperature of the water encounter higher and the injury more serious, while water does not liquefy and release heat when it encounters the human body.

The constant temperature here means that at that point in time of liquefaction, i.e., the same temperature as the water, but more heat energy is released.

Junior high school physics knowledge, which is worse to be scalded by 100 water vapor or 100 water?

The heat emitted by changing the shape.
