Is a white cloud a liquid, or a gas? Is white gas a gas or a liquid

It's liquid. The formation of white clouds is formed by the evaporation of water on land into water vapor, and then rising to the high altitude and liquefied into small water droplets or Xiaoice crystals formed by condensation.

Clouds floating in the sky are made up of many tiny water droplets or ice crystals, and some are made up of small water droplets or Xiaoice crystals mixed together. Sometimes it also contains some large raindrops, ice and snow particles, and the base of the cloud does not touch the ground and has a certain thickness. Cloud formation is mainly caused by condensation of water vapor.

On the other hand, the water surface of rivers, lakes and seas, as well as the water of soil, animals and plants, evaporates into the air at any time and becomes water vapor. When water vapour enters the atmosphere, it becomes clouds that cause rain, or condenses into frost and dew, and then returns to the ground, seeping into the soil or flowing into rivers, lakes and seas. Later, it evaporates (sublimation) again, and then condenses (condensation) and declines.

The cycle goes on and on. After the water vapor enters the lower atmosphere from the evaporation surface, the temperature here is high, and the water vapor contained is more, and if this hot and humid air is lifted, the temperature will gradually decrease, and at a certain height, the water vapor in the air will reach saturation. If the air continues to be lifted, excess water vapor will be precipitated.

If the temperature there is higher than 0°C, the excess water vapor condenses into small droplets; If the temperature is below 0 °C, the excess water vapor condenses into Xiaoice crystals. When these small water droplets and Xiaoice crystals gradually increase to the point where the human eye can recognize them, they are clouds. So white clouds are liquids in the strict sense of the word.

If we know evaporation, sublimation, condensation, and condensation, it is easy for us to understand how clouds are formed. The water in the ocean, lakes, plant surfaces, and soil evaporates all the time, turning into water vapor and entering the atmosphere. Moist air containing water vapor rises upwards for some reason.

During the ascent process, as the surrounding air becomes thinner and thinner, the air pressure becomes lower and lower, and the volume of the rising air expands. When it expands, it dissipates its own heat, so the temperature of the rising air decreases. When the temperature decreases, the ability to contain water vapor becomes smaller and smaller, the saturated water vapor pressure decreases, the water vapor in the rising air quickly reaches a saturated state, and the temperature decreases again, and the excess water vapor attaches to the condensation nucleus suspended in the air and becomes small water droplets.

If the temperature is lower than 0, the excess water vapor condenses into ice crystals or supercooled water droplets. They are gathered together, supported by updrafts, and float in the air as clouds that we can see.

It is a collection of relatively dispersed water droplets, which are liquid in nature.

White gas is actually a small droplet of water vapor after liquefaction, which is a liquid. When the water vapor in the air encounters a colder object, it liquefies into tiny water droplets and floats in the air, so the "white gas" we see appears.

1. What is the difference between the white gas of ice cream and the white gas of hot soup?

Water vapor is not visible, these so-called "white gas" are small water droplets, the surrounding air encounters ice cream, the temperature is lowered, liquefied into small water droplets; The "white gas" of hot soup is formed by the liquefaction of hot water vapor when it meets the air. So these two kinds of "white gas" are the same principle. The difference is in the temperature.

2. The "white gas" of ice cream is floating downward, and the "white gas" of hot soup is floating towards **?

Upward, life experience tells us that it is the same. The "white gas" of the ice cream has a low temperature, a high density, and is downward. The "white gas" of the hot soup has a high temperature, a small density, and an upward movement. The density is due to the thermal expansion and contraction of the gas, resulting in a change in volume.

Note: Water vapor liquefies when cold to form small water droplets, which are not gases. Liquefaction: Exothermic.

The popsicles taken out of the refrigerator and the white gas emitted after the water spring stove is boiled are all formed by the liquefaction of water vapor. In winter, because the water vapor comes out of the human body with heat, when you breathe, the water vapor that comes out of the mouth suddenly meets the external cold and liquefies, liquefied into fine droplets, from gaseous to liquid, into fine droplets suspended in the air.

White clouds are liquid water.

Clouds are visible polymers floating in the air composed of small water droplets or Xiaoice crystals formed by the liquefaction of water vapor in the atmosphere when cold.

Clouds are the tangible result of the vast water cycle on Earth. When the sun shines on the Earth's surface, the water evaporates to form water vapor, and once the water vapor is supersaturated, water molecules collect around the dust (condensation nuclei) in the air, and the resulting water droplets or ice crystals scatter sunlight in all directions, which gives the appearance of clouds. In addition, clouds can take on a variety of shapes, and they are divided into many types depending on the height and shape of the sky.

It should be in liquid form.

Clouds are visible polymer noises that are formed in the air by the condensation (condensation) of water vapor in the atmosphere, supercooled water droplets, ice crystals, or a mixture of them. Clouds are the tangible result of the vast water cycle on Earth. When the sun shines on the Earth's surface, water evaporates to form water vapor, and once the water vapor is oversaturated, water molecules collect around fine dust (condensation nuclei) in the air, and the resulting water droplets or ice touching dendrites scatter sunlight in all directions, which gives the appearance of a stove cloud.
