What s going on with the fog around the popsicle 10

You are right. When the water vapor in the air is cold, it condenses into small droplets that can be seen by the naked eye, and floats up to form a mist. Why is it not a phenomenon of sublimation?

Because fog is not composed of small ice crystals, the ice crystals are much larger and can only be produced in the upper-air atmosphere when updrafts are strongly disturbed. The key to both is that the water vapor caused by popsicles does not develop into ice crystals, so sublimation is non-existent.

Yes, it is the phenomenon of liquefaction of the moisture in the air around the ice cube when it is cold. As the air gets colder, the moisture content in the air becomes oversaturated.

This fog is formed by the liquefaction of the surrounding water vapor!

This is a question of the relationship between temperature and the state of matter, because the temperature of the popsicle is very low, and the surrounding water vapor liquefies into small water droplets when it encounters cold, and the small water droplets are the fog we see. When you put a piece of glass in front of the popsicle, you will notice that there are water droplets on the glass piece.

Sublimation refers to the direct transformation of a solid substance into a gaseous state, while fog is a liquid substance, so it is definitely not a sublimation phenomenon.

I'm coming, what you said is right, first of all, the temperature of popsicles in the air is lower than that of air, and the surrounding water vapor meets cold to form water mist, and the so-called sublimation phenomenon is directly formed by the solid state into a liquid state! For example, iodine will sublimate into a purple gaseous state at high temperatures!

The temperature of water vapor in the air is higher than that of the popsicle, and the heat transfer between the two occurs, and the temperature of the water vapor decreases to a certain extent, and a small amount of water gathers together to form a mist that we can see with the naked eye.

The condensation and fogging caused by the cold of the popsicle in the surrounding air should be studied.

He's not right, popsicles are cold, so the water vapor in the surrounding air will liquefy when cold and then it will turn into the fog you see. You're right.

That's due to the white mist produced by the liquefaction of the air when it is cold.

It is a small droplet formed by the condensation of liquefied water vapor in the air.

Air liquefies when cold, you are right.

you are right

That's due to the white mist produced by the liquefaction of the air when it is cold.

Are you in your third year of junior high school?

Physics will be talked about in the third year of junior high school! ~~

You're right, hehe, this little thing is real.

The white mist around the ice cream is a small droplet formed by the liquefaction of water vapor in the air around the ice cream when it is cold.

The white mist above the hot water is the small water droplets formed by the liquefaction of the water vapor produced in the hot water when it meets 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, China has a good record of using ice to relieve heat.

Later the royal palace had popsicles made of milk and sugar. In the time of Kublai Khan, the ancestor of the Yuan dynasty (about 700 years ago), there was a food cream similar to ice cream in the imperial palace, called ice cheese. At that time, the rulers of the Yuan Dynasty forbade people outside the royal family to make ice cheese.

It wasn't until the Italian traveler Marco Polo left China and returned to China that Yuan Shizu asked people to teach him how to make this kind of precious socks and clear lead. When Marco Polo returned, he passed on this method to the Italian royal family, which kept it a 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, and in 1777, ice cream was advertised on the streets of New York.
