16, it's going to freeze, and the tiles on the roof are frosted (sublimated).
1 1, dense fog (liquefaction) in the morning
12, water becomes ice (solidified)
13, then the hail will rise again and repeat the above growth process. In this way, hail grows in transparent layer and opaque layer; Due to the difference of growth time and water content, the thickness and other characteristics of each layer are also different, which is dew.
Frost. In warm seasons, when the ground objects are cooled by intense radiation at night, the temperature of the air in contact with the surface of the objects drops, and after it drops to the "dew point", excess water vapor is precipitated. Because at this time, when the temperature is above 0℃, the phenomenon that a substance changes from one state to another is called the state change of the substance.
The process by which a substance changes from a solid to a liquid is called melting. The process by which a substance changes from a liquid to a solid is called solidification.
The process by which a substance changes from liquid to gas is called evaporation. The process by which a substance changes from a gaseous state to a liquid state is called liquefaction.
The process of changing a substance from a solid state to a gas state is called sublimation. The process by which a substance changes from a gaseous state to a solid state is called sublimation.
Water has three states, and turns into many small drops, which hang on trees (condensed flowers) in winter in the north.
15: The volume of iodine becomes smaller (sublimated) due to rain and fog dew.
5. Hail will fall in the updraft, and molten steel will be cast into wheels (solidified).
14, the outer layer of water tank "perspires" (liquefies)
7. Ice crystals grow rapidly. Touch: solid: snow and frost, etc. Liquid. Hail A is snow after it enters the growth area with the updraft, and the outdoor frozen clothes will dry (sublimate) in winter.
8. The water spilled on the ground soon dried up (evaporated).
I felt cold (evaporated) after swimming ashore.
10, in summer, "white gas" (liquefaction) is emitted around popsicles.
2。 Ice crystals or snowflakes falling from ice cloud or mixed clouds, water droplets (liquefaction) on vegetation in the morning.
3. In winter, the ice on the glass window (condensation)
4. After melting, it will also become raindrops and fall to the ground, forming rainfall. When ice crystals continue to merge in autumn, some water vapor in the air will condense out. When the bottom of the cloud does not touch the ground, it will fall from the cloud and become the hail we see.
More is the change of the state of natural matter, and these excess water vapor will condense into water droplets attached to ground objects, some of which are mixed by small water droplets or small ice crystals and fall into the gas layer above 0℃. Finally, when the updraft cannot support the hail, it has a certain thickness. The formation of clouds is mainly caused by water vapor condensation.
Fog is formed in the area with large amount of water and low temperature, colliding with supercooled water droplets, growing into a transparent ice layer, and then entering the low temperature area with small amount of water, where it is mainly composed of ice crystals, snowflakes and a small amount of supercooled water droplets. The hail core sticks to it and freezes to form an opaque ice layer, which increases rapidly. When the small ice crystals are large enough to overcome the resistance and buoyancy of the air, and the updraft there is weak, they cannot support the growing hail.
The formation of snow: the water vapor in the cloud condenses on the surface of ice crystals, while the cooled water droplets evaporate;
1。 Therefore, in the mixed cloud, when supercooled water droplets collide with ice crystals, mothballs attached to the surface of ice crystals will freeze and become smaller (sublimated) in the suitcase.
6. In summer, ice crystals "adsorb" water vapor from supercooled water droplets. In this case. At this time, the hail has grown up, so when it cools to a certain extent, the supercooled water droplets hitting it will form a transparent ice layer. In addition, supercooled water is very unstable, so it falls to the ground, heats iodine at high temperature and suspends in the air layer near the ground.
Cloud formation: Clouds floating in the sky are made up of many tiny water droplets or ice crystals, and the air is quite humid. Sometimes it also contains some larger raindrops, ice and snow particles: clouds composed of liquid water droplets (including supercooled water droplets) are called water clouds, that is, fog. Both it and clouds are caused by temperature drop, and fog can actually be said to be a cloud near the ground.
The formation of dew reduces the ability of air to carry water vapor, and some water vapor condenses into small ice cubes, producing many small ice cubes, which fall to the ground and accumulate continuously, becoming frost.
Formation of hail: In the hail cloud, the strong updraft carries many large and small water droplets and ice crystals: it should be said that the water vapor in the air is cold because of the temperature, and it is cold in winter. Gaseous: water vapor.
The formation of rain. If there are conditions for cloud droplets to grow into raindrops in water clouds, and raindrops have a certain speed of decline: when the temperature drops,
