What is the change of water in life, quietly The ice flowers on the window glass in winter are chang

The snow that falls in the winter is the water becomes; The hoarfrost of the autumn morning is watery.

Ice is a colorless and transparent solid, which is formed by the solidification of liquid water, condensed in a frozen environment, and liquefied and dissolved by high temperature, which is a normal natural phenomenon.

It can be naturally formed or artificially manufactured.

Ice is the solid form of water in nature, and the temperature is above zero degrees Celsius under atmospheric pressure.

, the ice will begin to melt and turn into liquid water. A Japanese research team found that when the ice began to melt, it was a molecule of water inside the crystal.

The beginning of the transition from crystallization is an opportunity to help clarify the mechanism of structural changes in aqueous proteins.

When exposed to strong light such as electric lamps, the inside of the ice melts, and a snow-like shape called "ice flakes" emerges. From the Japan Institute of Molecular Sciences and Okayama University.

In order to investigate the phenomenon of ice melting from the inside, researchers used a computer to calculate what happens to ice, which is made up of about 1,000 water molecules, when heated.

What is water change in life, quietly: the ice flowers on the window glass in winter are changed by water, dangdang: the white air around the ice cream is changed by water, bright: the water is boiling, the water vapor coming out of the pot is changed by water, and the dew on the grass is changed by water.

The snowflakes in winter are changed by water, the dew drops on the lotus leaves in summer are changed by water, the frost on the leaves in autumn is changed by water, and the white air coming out of the children's mouths in winter is changed by water.

Hail is changed by water, and snow is changed by water.

The white gas around the ice cream is watery.

Who changed the ice flower on the window sash?

In winter, the ice on the glass is changed by water, because the inside of the house is warm and there is water vapor, while the air outside is colder, and in the place where the cold and warm meet, water droplets will be formed, which is the same as rain.

When it rains, cold fronts and warm fronts meet, and in places where cold and warm alternate, precipitation is formed, because when water vapor is cold, it will condense, and after condensation, raindrops will fall. In winter, the glass is equivalent to the front of cold air and warm air, and the warm steam in the house will condense into water droplets when it meets the cool steam of the glass, and then be frozen into ice flowers.

In the cold winter, the temperature difference between indoor and outdoor is large, and the water vapor with higher indoor temperature is directly condensed into a solid when cold on the inner surface of the door and window glass, so that the ice flower is formed, and the outdoor gas temperature is low, and it is not easy to condense on the outer surface Xiaoice of the glass.

In winter, the outdoor temperature is low, and the indoor temperature is high, and the indoor water vapor (gaseous water) encounters the cold window glass, there are roughly several situations: first, if the outdoor temperature is not particularly low, the water vapor "liquefaction in cold", release heat, from gaseous to liquid, at this time there will be a lot of water vapor on the inside of the window, you can scribble on it; The second is liquefaction first, and then the temperature difference continues to increase, and then from liquid to solid, and water becomes ice; Third, if the outside temperature is very low, or the temperature difference between the inside and outside of the room is very large, the water vapor will directly solidify into ice (inside the window) when it is cold, and change from gaseous to solid, mainly because the temperature difference is too large and needs to release more heat than "liquefaction".

There are also some examples, such as taking out a bottle of soda from the refrigerator in summer, and after a while, there will be a lot of "sweat beads" on the bottle, which is the liquefaction of water vapor when it is cold; Take out a popsicle from the freezer, you can still see it "smoking", and after a while, there will be a "layer of frost" on the popsicle, which is the water vapor in the air solidified by cold. The difference between the two is that there is a critical value for the size of the temperature difference.

The white gas around the ice cream that the refrigerator takes out in the summer becomes water.

The ice sculptures at the exhibition are changed by water, and the snow is changed by water.
