At 180 °C, water vapor takes the shape of a smoke because a high temperature makes its molecules very small, and then it becomes a fog-like shape.
-
At 180 degrees, the shape of water vapor in the air should be foggy, and in the vacuum it is liquid.
-
It is not that water does not turn into vapor until it reaches 100°C, but that at standard atmospheric pressure, all water turns into vapor when it exceeds 100°C.
In fact, all liquids volatilize, and there is a maximum value of vapor pressure at a certain temperature, which is called saturation vapor pressure. When the vapor pressure above the liquid reaches the saturated vapor pressure, the number of volatile molecules in the liquid and the number of molecules returning to the liquid from the air remain in equilibrium.
The saturated vapor pressure of water at 100°C is equal to the standard atmospheric pressure, and when the water temperature tries to exceed 100°C, the vapor pressure above the water surface must exceed the standard atmospheric pressure to reach equilibrium, but this is not possible in open space, so the water absorbs heat through rapid volatilization (boiling), so that the water temperature is kept at 100°C and does not continue to rise, until the water has completely volatilized, and the temperature can continue to rise.

The landlord may have thought that water would only change from liquid to gaseous at 100 degrees, i.e. "vaporized". Of course, this is not the case, otherwise you will never dry your laundry. We often say 100 refers to the boiling point of water (in the standard state of 4 and 1 atmosphere), liquid water reaches this temperature and continues to absorb heat will "boil", boiling is a violent gasification phenomenon, in addition to water on the surface, vaporization also occurs inside the water, because the water inside absorbs enough heat, becomes gaseous into bubbles on the surface, we call boiling.
So reaching 100 (and continuing to absorb heat) is only necessary for water to boil, not "necessary for water vapor to exist".
-
At 180 degrees Celsius, the water vapor is basically formless and colorless, because it will vaporize at this time.
-
180° ambient water vapor. It must have been a mist, and although this mist of water vapor drifted in the air, the temperature was very high. Being able to write can cause physical injuries to people.
-
At 180 degrees Celsius, water vapor is shaped like a gas, just like oxygen and carbon dioxide molecules.
-
In the environment of 180°, it is the rotation of steam, she should have atomized water, and it is already boiling at 100°, so in the environment of 180°, it is a state of atomization.
-
In 180 words, there is water vapor today, it is a pure gaseous state, and then that is to say, if you are in the state of water vapor, you are not a situation that you can see, if you can see its gas state, it is contracted with it that it has liquefied, and what you can see is its water droplets, not its water vapor.
-
At 180 degrees Celsius, water vapor is in a vaporized form.
-
Generally, it is gaseous, because 180 degrees Celsius causes water to evaporate, and generally, water above 100 degrees Celsius will be converted into water vapor, so it is 100% gaseous.
-
At 180 years old, the shape of water vapor has changed to the shape of gas, that is, water molecules that are not visible directly.
-
It is in the form of a gaseous molecule, free in the air, in the form of a gas.
-
In this case, the water vapor should be atomized.
-
Water vapor is placed near 180°. When the water is heated to 100°, it will boil and boil, and it will hide in the water vapor. 180°, that's who really knows how to connect quickly.
-
I just remember that he just had each other and turned into gas, and he couldn't see anything, and it was the donkey stew mentality.
-
At 180 degrees Celsius, the water vapor turns into fog and is gone.
-
In an environment of 180 degrees, the water vapor will evaporate, and we should all know that 100 degrees is the evaporation point of water.
-
What happens to water vapor at 180? It will evaporate very quickly, because when the temperature reaches a certain temperature, it will evaporate very quickly.
-
Under normal pressure.
Water vapor at 180 degrees Celsius is gaseous.
Under high pressure, a liquid state may also occur.
-
In the maximum environment of 180 degrees, the reason why its water vapor is formed is also caused by the natural environment, and this is also a scientific process for us.
-
In the environment of 180 degrees Celsius, it is always tied, why is the shape of water vapor certainly not only affected by temperature? It is also affected by other aspects, by the specific situation, the specific situation.
-
Entering the water in a 180° room is really why the shape is so good. In the case of medium water vapor still. Or the shape of the water injection is still formed, we will not see.
-
I felt that the water vapor in that environment fell into a good shape, but it eventually turned into steam.
-
In this environment, it is considered high, and the water vapor is to look at the gas.
-
I also can't decide what the shape of water vapor is at 180 degrees, which seems like we haven't seen it before.
-
What shape is it? Actually, I don't know much, but at 180°, he has all become level seven, and he can't see it.
-
This user must be present with 7 small droplets.
-
In a 180-degree environment, if you really go to things, things are the same as each other, you can't see things at all, he has a way, you feel foggy.
-
In more than 180 rooms, the water vapor is immediately evaporated.
-
Water vaporThere is no fixed shape, there is volume.
When water is in the gaseous state, the distance between the molecules of water vapor is large, whereas after condensation into water, water molecules.
The distance between them becomes smaller, and the volume becomes smaller.
Water vapor, is the gaseous form of water (H2O). When water reaches its boiling point, it becomes water vapor at a standard atmospheric pressure at sea level.
, the boiling point of water is or 212°F.
Evaporation phenomenon. The vaporization process that only takes place on the surface of the liquid. Evaporation can occur at any temperature. The evaporation process absorbs heat and evaporates to cool.
Factors that affect how fast or slow evaporation is: temperature, wet state divergence, surface area of the liquid.
air movement on the surface of a liquid, etc.
The process by which water transitions from a liquid or solid state to a gaseous state and escapes into the atmosphere is called evaporation. It refers to the fact that the water comes into contact with the air at the normal lead ridge temperature, and the locust trace seeps into water vapor. Evaporation refers to the amount of water that is dispersed into the air by evaporation over a certain period of time.

Liquid. Solid: Noisy Laughter has both a fixed volume and a fixed shape.
Liquid liter containment state: There is a fixed volume but no fixed cavity shape, the amount of liquid of the same substance is loaded into different containers, and its shape is the same as the inside of the container, but the volume does not change with the container. For example, when a glass of water is poured into a basin, the shape changes but the volume does not change.
Gaseous: Neither fixed volume nor fixed shape, the amount of gas of the same substance is packed into different containers, and its volume and shape are the same as the inside of the container. For example, if the gas of a balloon is placed in a closed room, the gas will quickly spread and fill the whole room, and the volume and shape will change.

Water vapor is what water has no fixed shape and volume as follows:
When water is in the gaseous state, the distance between the molecules of water vapor is large, and after condensation into water, the distance between the water molecules becomes smaller and the volume also decreases.
Water vapor, which is the gaseous form of water (H2O). When water reaches its boiling point, it becomes water vapor, and at a standard atmospheric pressure at sea level, the boiling point of water is or 212°F.
When water is below the boiling point, water can also slowly evaporate into water vapor, while in a very low pressure environment (less than atmospheric pressure), ice will directly sublimate into water vapor, which may cause the greenhouse effect, which is a greenhouse gas.

This is applied to the knowledge of phase states in inorganic chemistry at the university, where water exhibits three different phases at different temperatures and pressures. Of course, from your question, you can tell why there is water vapour at 0 100 degrees Celsius at atmospheric pressure.
The water molecules have been sitting in irregular motion, especially the water molecules near the water surface, the probability of its movement in all directions is the same, but because of the mutual gravitational attraction between the water molecules, only a few imitation of the banquet can escape, but because of the large base, so the number is considerable. At the same time, it is considered that the activation of molecules at higher temperature can reduce the low reserve silver, and the number of molecules that can escape from grinding and rolling increases
Didn't go to the book anymore,

To put it simply, water will evaporate, and evaporation can take place at room temperature.
Further, the vapor pressure of water at room temperature and pressure is related to the nature of water, which can be simply explained as the energy required for water molecules to evaporate from van der Waals forces and hydrogen bonds. At room temperature, water molecules on the surface will randomly gain enough energy from the environment to evaporate. The amount of evaporation depends on the humidity of the air (there is a limit to the amount of water molecules that a certain amount of dry air can hold) and the air pressure and temperature.
100 The water is constantly supplied by an energy source to allow the water molecules to evaporate from the constraints of van der Waals forces and hydrogen bonds, and is not limited to the water on the surface, but according to the convection effect, all positions of the water reach the energy required for evaporation, so the bubbles are constantly generated from various positions where bubbles can be formed, and they become larger, causing the water to vaporize violently, and the energy provided by the energy source is much greater than the energy provided by the environment, so the boiling is much more intense than the evaporation.

Water vapor is everywhere in the air, increasing the velocity of the liquid surface air or the surface area of the liquid. That's definitely right.
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.
According to the statistics of previous years, the average height of women in our country is about 160cm. Women in the north are slightly taller, with an average height of 162cm, and women in the south are slightly shorter, with an average height of 158cm. But women's height has been rising, and it's no surprise that women are 180+ years later. >>>More
Isn't that a beautiful height match? The height difference of 10cm, think about it, it's a cute picture. Today's boys hope that they will be the strong party in love, of course, height suppression is a key, and girls also hope that their boyfriends can be taller and have a sense of security. >>>More
In fact, Hugo's words have nothing to do with the construction of cities, he means that the sewers of the city are the habitat of the exiles and the vulnerable, and the sewers shelter them, so the sewers are the conscience of the city.
