Ice. The three states of water.
a) Water can be transformed into solid ice, liquid water, and gaseous water vapor.
This is called the tri-state of water
1.The water in the freezer in the refrigerator forms an icy solid substance.
2.An ice-like solid substance that dissolves into liquid water.
3.The water boiled in the kettle will change from liquid water to water vapor, but at the spout of the kettle.
The white smoke you see is the condensation of water vapor when it is cold.
into small droplets of water.
4.The water vapor in the air condenses into small liquid water droplets, clouds and fog.
b) Water changes its state due to changes in temperature.
1.The temperature at which water freezes is 0 is called the melting point.
2.When the water is boiling, there will be a phenomenon of bubbles coming out, which is called boiling. The temperature at which water boils is 100 is called the boiling point
c) Water vapor in the air.
1.When boiling, the surface of the water is constantly rolling, resulting in the phenomenon of water convection, and many bubbles rise upward, and when they rise to the surface of the water, they become invisible water vapor.
2.Water vapor is invisible, and the white smoke seen when water boils is a small droplet of water vapor condensed when it meets cold, instead.
Water vapour. 3.The phenomenon of water vapor condensing into small water droplets when it is cold is called condensation.
4.Boiling water produces water vapor, which comes out of the water, thus reducing the amount of water and heating the liquid into gas.
The phenomenon of the body is called vaporization.
4) Common phenomena in daily life.
1.When boiling dumplings or noodles, you can see the water surface rolling when the water is boiling, and you can see many small droplets (white smoke) condensed by the cold water vapor.
2.When eating hot pot or cooking anything, you can see a lot of white smoke (small droplets of water vapor condensed when it meets cold).
3.The clouds in the sky are also small droplets of water condensed by the rise of water vapor in the air and cold.
4.Pour the iced drink into the cup, and soon, there will be many small droplets on the outside of the cup.
5.White smoke next to the popsicle: When eating a popsicle, the white smoke around the popsicle is also a small droplet of water condensed by the water vapor in the air when it encounters the cold of the popsicle.
6.When I opened the freezer of the refrigerator, I could see a puff of white smoke descending, which was also the condensation of the water vapor in the air when it was cold.
into small droplets.
5) The three states of matter.
1.The distance between the molecules of solid matter is very small, and the attraction to each other is firm, so solid matter has a certain shape.
and volume. 2.The distance between the molecules of a liquid substance is relatively large, and the molecules are not so tightly bound to each other, so the water will flow.
3.The distance between the molecules of a gaseous substance is the largest, so the gas does not have a certain shape and volume.

Also known as dry water, it contains more than 98% water, and is an ecological and environmentally friendly product integrating microorganisms and chemical technology. Solid water has the physical characteristics of a solid substance as compared to ordinary water. At room temperature, it does not flow, does not evaporate, does not freeze at 0 degrees Celsius, and does not melt at 100 °C.
It looks more like an elastic gelatinous body on the outside. Therefore, it can be transported, used and stored by conventional means at room temperature. The singularity of solid water lies in the fact that it does not evaporate when exposed to the air and does not permeate into the soil.
Biodegradation occurs only in soils where there are microorganisms around plant roots, which are reduced to free water and released.

What does solid water mean1Solid water, also called dry water in foreign countries, contains more than 98% water; 2.Solid water is an ecological and environmentally friendly product integrating microbial and chemical technology; 3.
Solid water has the physical characteristics of a solid substance as compared to ordinary water. Quiet beam at room temperature, do not flow cautiously, do not evaporate, do not freeze at zero degrees Celsius, and do not evaporate at 100 degrees Celsius; 4.The outside of solid water is more like an elastic gelatin, so it can be transported, used and stored by conventional means at room temperature; 5.
The strange thing about solid water is that it does not evaporate when exposed to the air, it does not permeate when it spreads into the soil, and it only biodegrades in the soil where there are microorganisms around the plant roots, and is reduced to free water release.

Solid water is ice, and when the liquid water temperature reaches below freezing, it freezes, which is a natural physical change caused by low temperatures.

Introduction to Solid Water:
1. Solid water, also known as dry water in foreign countries, contains more than 98% of water;
2. Solid water is an ecological and environmental protection product integrating microorganisms and chemical technology;
3. Compared with ordinary water, solid water has the physical characteristics of solid substances. At room temperature, it does not flow, does not evaporate, does not form slow ice at zero degrees Celsius, and does not evaporate at 100 degrees Celsius;
4. The outside of solid water is more like an elastic gelatin, so it can be transported, used and stored by conventional means at room temperature;
5. The singularity of solid water is that it is exposed to the air and does not evaporate, and it is not permeable when it is dispersed into the soil, and it is only biodegraded in the soil where there are microorganisms around the plant roots, and it is reduced to free water and released.

Kiss! Hello, happy to answer your <>
Hydrophilic containing SSDs are: Solid water (abbreviation: dihydrogen monoxide, chemical formula:
h o) is an inorganic substance composed of hydrogen and oxygen, which is non-toxic and drinkable. It is a colorless and odorless transparent liquid at room temperature and pressure, and is known as the source of human life. Water can be divided into natural water (rivers, lakes, atmospheric water, seawater, groundwater, etc.) [containing impurities], distilled water [theoretically pure water], and artificial water (water obtained by combining hydroxide and oxygens through chemical reactions).
Water is one of the most common substances on the earth, an important resource for the survival of all life, including the inorganic chemical combination of human beings, and the most important component of living organisms. Water has played an important role in the evolution of life. It is a narrowly non-renewable, broadly defined renewable resource.
Pure water can conduct electricity, but it is very weak (conductivity can be ignored in daily life), and it is an extremely weak electrolyte. Water in daily life has more positive and negative ions due to the dissolution of other electrolytes, and the conductivity is enhanced. Hope mine can help you <>

1. Classification: gaseous: cloud.
Liquid: Rain. Solid: snow, hail, frost.
2. Classification reasons:
1. Clouds are gaseous.
A gaseous gas is a fluid like a liquid: it can flow and it can be deformed. Unlike liquids, gases can be compressed. If there is no restriction (container or force field), the gas can diffuse, and its volume is not limited.
2. Rain is liquid.
The liquid state is different from the gaseous state, which has a certain volume. The liquid state, unlike the solid state, is fluid and therefore does not have a fixed shape.
3. Snow, hail, and frost are solid.
Compared with liquids and gases, solids have a relatively fixed volume and shape, and the texture is relatively hard. Solids are divided into crystalline and amorphous, crystals have a fixed melting temperature, and amorphous does not have a fixed melting temperature.
The capacitance in the full state is much better. But there are individual special places that are good in a half-old state. >>>More
Low-capacity flash-based SSDs consume less energy and heat in the operating state, but high-end or high-capacity products consume more energy.
Solid State Disk (solid-state disk), that is, a hard disk made of a solid-state electronic memory chip array, consists of two parts: a control unit and a storage unit (DRAM or Flash chip). The storage unit is responsible for storing data, and the control unit is responsible for reading and writing data. It has the advantages of fast speed, durable and shockproof, no noise, and light weight. >>>More
