The reason dry ice smokes when placed in water is that the temperature of the dry ice itself is very low. When placed in water or air, it quickly absorbs heat and sublimates, condensing nearby water vapor. the air in countless small water points. It is a white fog that looks like smoke. This has the same meaning as the “white mist” produced by ice in summer. These are all small water droplets, no other gaseous substances.
Dry ice is solid carbon dioxide. At room temperature and a pressure of 6079.8 kPa, carbon dioxide condenses into a colorless liquid. As the temperature continues to drop and the low pressure increases, the liquid quickly evaporates and condenses. in a piece of pressure. A compact solid substance similar to ice is dry ice.
WhenAs dry ice turns into a gas when heated, it condenses water vapor in the surrounding air into countless small spots of water, resulting in a white fog. If you pour hot water over dry ice, the white mist will appear thicker, like a fairyland.

Applications of dry ice in food preservation
Put dry ice in a food warehouse or in a train refrigerator, which Lowering the temperature can prevent bacteria from multiplying, thereby keeping fish, meat and fruits fresh. Dry ice has benefits that ice cubes can't match.
For example, it is light and weighs about 1/18 the same volume of water ice. Lightness makes transport easier. Additionally, dry ice leaves no liquid behind after sublimation, making it cleaner than rrefrigeration based on water ice and does not make food moist.
At the same time, the density of carbon dioxide generated after the sublimation of dry ice is greater than that of air. Therefore, carbon dioxide will attach to the surface of heavy foods, isolating them from oxygen and inhibiting them. the growth of bacteria and slow down its metabolism. Make sure fruits, vegetables and seafood are fresh and not spoiled.
It is worth mentioning that using dry ice to prepare delicacies can also create a warm and romantic atmosphere, making diners feel like they are in a fairyland. Nowadays, using dry ice to prepare delicious dishes has become a must-have for many high-end hotels.
Everyone knows that hot water cannot be put directly into the refrigerator, so what happens if you mett a cup of hot water straight from the refrigerator? Will it explode if you put hot water in the fridge?
What will happen if you put a cup of hot water in the refrigerator? This will cause food in the refrigerator to deteriorate.The temperature in the cold room of the refrigerator is generally maintained at around 4 degrees Celsius, which can provide better preservation of food. But if you put a cup of hot water in the refrigerator, the temperature inside the refrigerator will rise, which will affect the preservation of other foods in the refrigerator and even cause some foods to deteriorate.
Affects the life of the refrigeratorIf you put a cup of hot water directly into the refrigerator, in order to maintain a low temperature environment, the refrigerator must increase its operating efficiency to lower the temperatureerature, which increases the number of refrigerators. If this happens for a long time, it will affect the use of the refrigerator and shorten its life.
Causes freezing in the refrigerator.If hot water is placed directly in the low temperature environment of the refrigerator,When hot water encounters cold air, it will accelerate its evaporation rate, which will produce water vapor water in the refrigerator. If this water vapor is adsorbed on the interior wall of the refrigerator, it will form a refrigerator. , it will affect its work efficiency.
Will it explode if you put hot water in the fridgeUsually no.
Putting hot water in the refrigerator will generally not cause the refrigerator to explode, but it will affect the preservation of other foods in the refrigerator and the life of the refrigerator, so it is not recommended to put it directly. Put the hot water in the refrigerator. If you want to put it in, let it cool naturally to room temperature before putting it in the refrigerator.
How to remove ice cubes from the refrigerator1. Turn off the power to the refrigerator, then remove all food from the refrigerator
2. Take 1-2 bowls; and put them in the bowl. Fill the hot water, put it in the refrigerator and close the refrigerator door;
3. Put the hot water in the refrigerator for about 30-60 minutes, steam hot. will melt ice cubes in the refrigerator;
4. After the time is up, remove the water if there are still ice cubes in the refrigerator, you can use a shovel to lightly clean them; /p>
5. Finally, use a clean towel to clean them. Wipe the inside of the refrigerator and turn on the refrigerator;
6. Once the refrigerator has completely cooled, you can. to put backthe food in it.
How to eliminate odors in the refrigerator. Use toilet paper.Toilet paper has a certain degree of adsorption. If there is a smell in the refrigerator, you can take a roll of toilet paper and put it in the refrigerator. , which will reduce foreign objects in the refrigerator.
Tea bagTake an appropriate amount of tea, wrap it in gauze, and then put it in the refrigerator to absorb odors. However, it should be noted that the tea should be removed every 1-2 months. or so. Take out the bag and dry it in the sun.
