Why are there water droplets on the beverage bottles taken out of the refrigerator in summer?

Because the mineral water has just been taken out of the refrigerator, its temperature is much lower than the indoor temperature in summer. When the hot air in the air encounters the cold mineral water, it will produce heat around the mineral water. After understanding the physical phenomenon of liquefaction (i.e., gas turns into liquid), water vapor turns into small water droplets, which is the white gas we see. In fact, it is composed of many small water droplets

This is the principle of liquefaction mentioned in junior high school physics. Gases will liquefy when they are cold. Each gas will have a freezing point, which is the temperature required for gas liquefaction. When the temperature of the object the gas touches is equal to or lower than When it reaches the freezing point of the gas, the gas will liquefy into a liquid. We call this process liquefaction

These are common sense to contemporary people and will be learned in compulsory education. When the beverage bottle is taken out of the refrigerator, the temperature is lower than the outside temperature, and the water vapor in the air will liquefy when it is cold. The liquefied small water droplets are adsorbed to the beverage bottle. The small water droplets accumulate more and more, and finally the drink looks like a drink. There is some water on the bottle.

Water turns into water vapor, and the small droplets formed in the air look like white mist (gas) to the human eye. The test is also very simple. You can use an alcohol lamp to put a beaker on the beaker and put a cold glass on it. To the water evaporation and liquefaction process.

In summer, the temperature is higher and the ice cream temperature is lower. When the air is cold, it liquefies and liquefies into small water droplets and becomes mist, so "white gas" will appear

Man is a warm-blooded animal. When the weather is cold, the temperature of the human body is higher than that of the air. The temperature of the gas emitted is high, and when it encounters cold air, it liquefies into small water droplets, which is the gas you see.
