The white gas emitted from the popsicle is downward.
The white gas emitted by the popsicle is not actually gas, but water vapor in the air.
Small water droplets when exposed to cold. These tiny water droplets go down because they are denser than air.
The density of water (4) is that of air. Obviously, the density of water is greater than that of air, so it will go down.
Density and buoyancy.
The object is in the water.
Object < water, where the object floats (floats).
Object = Water, the object is suspended.
Object》 Water, the object sinks to the bottom (sinks).
For any liquid.
Objects < liquids, objects float (or float).
Object = Liquid, the object is suspended.
Object liquid, the object sinks to the bottom (or sinks).
When the object is liquid (the object floats or is suspended).
Volume of the object in water: Volume of the object = Object: Liquid.
When object = water (object) is suspended, the volume of the object in the water: the volume of the object = 1:1

The air emitted from the popsicle is theoretically downward.
In summer, there is a large amount of water vapor in the air, and the water vapor meets the cold popsicle and liquefies to form small water droplets, that is, "white gas", because white gas is small water droplets, and the density is greater than the density of air, so the "white gas" coming out of the popsicle moves downward.
-
The white gas emitted from the popsicle is downward.
Because this white gas is a small droplet produced by the cold of water vapor in the air. These small water droplets are decreasing because they are denser than air.
At room temperature and pressure, the density of water is 1g cm3, while air is. It can be seen that the density of water is much higher than that of air, so it will decrease.
-
The white gas from the popsicle floated downward.
Reason: Because "white gas" is actually a small droplet formed by the liquefaction of water vapor in the air, its average density is greater than the average density of the air, so the white gas emitted by the popsicle floats downward.
The density of the liquid is greater than that of the air and it sinks.
First of all, it is necessary to understand that this "white gas" is not a gas, but like a fog. The reasons for its formation are as follows:
Popsicles are colder than the surrounding air, and the water vapor in the air (note that water vapor is invisible, it is a gas) will "liquefy" when it is cold, and many small water droplets together form "white gas". It's like the breath that comes out of our mouths in winter.
Relationship between density and buoyancy:
1. The object is in water.
Object < water, where the object floats (floats).
Object = Water, the object is suspended.
Object》 Water, the object sinks to the bottom (sinks).
2. For any liquid.
Objects < liquids, objects float (or float).
Object = Liquid, the object is suspended.
Object liquid, the object sinks to the bottom (or sinks).
When the object is liquid (the object floats or is suspended).
3. The volume of the object in water:
Volume of Object = Object: Liquid.
When object = water (object) is suspended, the volume of the object in the water: the volume of the object = 1:1
-
The white gas coming out of the popsicle will fall downward.
The white gas emitted by the popsicle actually liquefies the water vapor in the air into small droplets, because the density of the small droplets is greater than the density of the air, so the white gas should fall downwards instead of upwards. Cold air is less dense than hot air, so it runs down, driving these small droplets down.
-
It's downward, because this white gas is not actually a gas, but a small droplet of water vapor in the air when it is cold (near a popsicle). These tiny water droplets are denser than air, and of course they go down!
-
It should be downward.
White gas is actually small water droplets in liquid form, which are obviously denser than air, so downward.
In addition, the white gas emitted when boiling water is also downward. On the surface, it looks up, but in fact it is down. When a layer of white gas is formed, it will immediately fall downward; But in the moment after it was formed, another layer of white gas formed on top of it, so it felt like the white gas was rising.
Whether it is the white gas of the popsicle or the white gas of boiling water, it all falls downward.
-
Generally, the water vapor in the downward air is liquefied by cold and becomes small water droplets, which are larger in density and mass than the surrounding air, causing a decline.
But coupled with geographical factors, the rapid rise of the surface thermals in summer will lead to an upward state of "white gas".
-
That's a physical phenomenon, it emits white gas because of the difference in temperature, in fact, those white gases are small water droplets, he thinks there are all directions around

Upstairs and downstairs are neighbors, don't fight for a trivial matter, little brother, listen to me, of course, upward, have you read junior high school? This is taught in junior high school. Since ice is solid, it is directly sublimated into a gaseous state, and if you don't know what sublimation is, you don't need to rush, you will understand it in junior high school.
It's a pleasure to be able to help you with what I've learned....Hope support.
-
Downward, the gas expands and contracts, the gas cools, the density increases, and the density increases, and it naturally floats downward.
-
downward, because carbon dioxide is denser.
-
Drift downwards because air is denser than cold air.
-
There is water vapor, water vapor, naturally upward.
-
The white gas coming out of the popsicle will fall downward. The white gas coming out of the popsicle actually liquefies the water vapor in the air into small droplets, because the density of the small droplets is greater than the density of the air, so the white gas should fall downward.
Water vapor, or simply water vapor or steam, is the gaseous form of water (H2O). When water reaches its boiling point, it turns into water vapor. At one standard atmosphere at sea level, the boiling point of water is or 212°F.
Water can also slowly evaporate into water vapor when it is below the boiling point. In a very low pressure environment (less than atmospheric pressure), ice will directly sublimate into water vapor. Water vapor may contribute to the greenhouse effect and is a type of greenhouse gas.
In addition, water vapor is not an energy source, nor is it a secondary energy source, nor is it a renewable energy source, water vapor is just a manifestation of the existence of water in a gaseous state.
Gaseous water is a small but important component of the atmosphere. Approximately there is in the troposphere. The phase of condensation water vapor to liquid or ice is mainly done by clouds, rain, snow, and other sediments, all of which are also the most important weather elements.
Fog and clouds are formed by condensing the surrounding clouds to condense nuclei. In the absence of nuclei, condensation can only occur at lower temperatures. After continuous condensation or deposition, cloud droplets or snowflakes form and contribute to their critical mass.
The average residence time of water vapor in the stratosphere is about 10 days. Water replenishment, precipitation, evaporation, is the result of transpiration, and other biological and geological processes in oceans, lakes, rivers, and plants.
Measuring water vapor concentrations is expressed as specific humidity or relative humidity. If precipitation were to condense immediately, the annual global average of water vapor would bring only about 25 millimeters of precipitation across the Earth's surface. However, the average annual precipitation is about 1 meter, which indicates a rapid turnover of water in the air.
Although the amount of gas emitted by volcanoes varies widely, water vapor is always the most common volcanic gas, and more than 60% of the emissions from volcanic eruptions are usually water vapor.
-
The reason why the popsicle is white and white is because the water vapor in the air next to the popsicle condenses into small droplets.
Since cold air is less dense than hot air, it will run downwards and drive these small droplets downwards as well.
-
Hello, it must be floating down, because the white gas coming out of the popsicle is actually a small droplet of water vapor around the popsicle condensed, so it must be heavier than the air, so it floats down!
-
This white gas is a small water droplet formed by the condensation of water vapor in the air when it is cold, and the density of the small water droplets is greater than that of the air, so the white gas falls downward.
-
Float downward.
White gas is formed by the liquefaction of water vapor in the air into small water droplets when cold, the density is greater than the density of the air, and the buoyancy is less than the gravity, so it is downward.
-
Of course it's floating upwards... Didn't you pay attention when you ate ice cream?
After evaporation, the vapor runs upward, and the density of the air coming out is less than that of air.
-
You often hear the forecast of the meteorological station, is the cold air falling, and how many degrees will the temperature rise when the weather is hot?
That's how it works: the cold goes down, the heat goes up.
-
The popsicle causes the water vapor in the nearby air to liquefy into small droplets, which look like a white mist that is denser than the air, and therefore sinks downward.
-
Popsicles will lower the temperature of the space around them, causing the water vapor and dust in the air to combine and liquefy to form small droplets, which we can see fluttering like "smoke" with the flow of air when the small droplets accumulate a certain amount. Actually, it should be fog... Hope to adopt.
-
In summer, there is a large amount of water vapor in the air, and the water vapor meets the cold popsicle and liquefies to form small water droplets, that is, "white gas", because white gas is small water droplets, and the density is greater than the density of air, so the "white gas" coming out of the popsicle moves downward.
Therefore, the answer is: water vapor meets cold popsicles and liquefies to form small water droplets, that is, "white gas"; Under; White gas is small water droplets, denser than air, so the "white gas" coming out of the popsicle moves downward
-
The white mist around the ice cream is in the air around the ice creamWater vaporSmall water droplets formed by liquefaction in cold.
The white mist above the hot water is a small water droplet formed by the water vapor produced in the hot water meeting the liquefaction of the cold air above.
Due to the high temperature and low density of the hot water vapor, it rises, causing the white fog above it to rise as well.
Due to the low temperature and high density of cold water vapor, it drops, causing the white fog around it to drop as well!
Origin
Popsicles. China is the homeland of popsicles. As early as more than 3,000 years ago, there were records of using ice to relieve heat in China. Later the royal palace had popsicles made of milk and sugar. to the Yuan ancestor Kublai Khan.
At the time (about 700 years ago), there was a similar ice cream in the palace again.
of food, called ice cheese. At that time, the Yuan Dynasty.
Rulers forbade people outside the royal family to make ice cheese.
Until the Italian socks clear lead traveler Marco Polo.
Before leaving China and returning to China, Yuan Shizu asked people to teach him how to make this treasure. When Marco Polo returned, he passed on this method to the Italian royal family, who kept it secret for about 300 years, until 1533, when the King of France married an Italian.
The method of making ice cream was introduced to France from Italy in 1777 in New York, USA.
Ice cream ads were just popping up on the streets.

It's going down, because when the air is cooled, the spacing between the molecules in the gas is shortened, so its specific gravity increases, so it goes down, and the same hot air goes up, like the steam you see.
-
Float downward. It should be that the density of the cold air is greater than that of the air, so it will sink.
You can open the refrigerator in your own home, and it is obvious that it is going down.

I'll help you :
The white air of the ice cream bubbles downward. Because this is a liquefaction phenomenon, that is, when the water vapor cools down, it turns into small water droplets.
Due to the low temperature around the ice cream, the water vapor around the ice cream liquefies into small water droplets, and many small water droplets form white gas.
Since the white gas is made up of small water droplets, their average density is greater than that of the surrounding air, so the white gas rises downward. Because the density is high, it is easy to sink.
I hope it will be helpful to you, and I wish you progress in your studies!

Popsicles are a thirst-quenching food that people all over the world love. Like water, it is cool and sweet, originated in China, and is suitable for summer consumption. It is simple and reasonable to make, so it is very popular with people, but it generally dissolves quickly at room temperature.

Precautions for eating popsicles
1. Do not eat before and after meals: eating before and after meals will affect appetite, due to the low temperature of ice cream, it will cause gastrointestinal vasoconstriction, which will affect its digestion and absorption ability and affect the absorption of various nutrients. If you want to eat it, it is recommended to put it between meals.
2. Don't refreeze the ice cream after melting: Freezing the ice cream after thawing will reduce the quality of the ice cream and easily breed bacteria. Therefore, when purchasing ice cream, try to store it in a closed freezer at -18 degrees Celsius. If the packaging is intact, do not buy the deformed ice cream, it is very likely that it will be thawed and deformed during transportation or sale and then re-frozen.

To be clear, this is a very normal phenomenon, because when you say white gas, it is actually formed by the condensation of water molecules floating in the air, but when the quantity reaches a certain level, blocking the light will show its own color, that is, white, because it itself is actually moisture, and its specific molecular weight is heavier than our daily air.
That's from the point of view of gravitation. The gravitational pull of the beast will cause the heavy things to sink down, and the light things will delay the two objects that are rich but incompatible in the same space. If you are together, heavy objects will sink downward, while light objects will be taken up if you are squeezed at the bottom.
You can see this by doing an experiment with oil and water, the oil and water mixture, you stir it together, but when it is standing, the clear object will be on the upper layer. There will be a phenomenon where a heavy object slides down, and a light object goes up, but if you say cold air, it will sink downward. He's heavier than normal air, and he's going down.
This is just the most common physical phenomenon.
To be clear, this kind of physics course should have been explained in detail in elementary school. You can even have a very detailed explanation.
