Coke can't be frozen directly.
Too low a temperature will expand the gas, which will lead to an explosion.
Heating will make the gas expand and eventually exceed the bearing limit of packaging materials, which may lead to the explosion of cans! If you freeze below 0℃, the volume of the liquid will expand and the tank will burst. That's it, so coke cans can't be heated or frozen at 0℃! Because Coca-Cola is a carbon dioxide beverage, overheating and supercooling will release carbon dioxide from the liquid, so let's not talk about explosion. It tastes bad, too! The optimum drinking temperature is about 15-25.
All unopened carbonated drinks and beer must not be put in the freezer, but can be put in the freezer, because the temperature of the freezer is basically around-15 degrees. If you want to drink frozen carbonated drinks, you can pour them into the ice box without filling them up, and the height of 70 cents is enough. Leave room for drinks to expand, and then you can take them out to eat or add them to wine or other drinks.
Practice of freezing coke
Prepare a bottle of coke, bottled or canned.
Shake the bought bottled coke vigorously, so that it produces rich foam inside.
Put the shaken coke in the freezer and take it out four hours later.
After taking out the coke, gently lift the bottle cap, and then rotate and shake the bottom of the bottle upward.
Take out the cup and pour the coke in. At this time, you will find that coke has become a semi-solidified body like a smoothie, and it is very refreshing to drink with a long spoon.
There is also an ordinary frozen coke.
Pour coke into a cup, put it in the refrigerator for a few hours, and then take it out to drink.
Matters needing attention of canned coke in freezer
First, when the temperature drops, the volume of water will increase. When water freezes, its volume expands. Therefore, the volume of frozen coke is much larger than before, which will deform the tank and even burst. For example, the picture below.
Second, when the liquid freezes * * * or partially freezes * * *, the solubility of gas will change, and the dissolved carbon dioxide in coke will be released, which will increase the pressure in the tank. Coupled with the influence of the increase in the volume of cola liquid itself, there will be great pressure in the tank. It's very dangerous to open it at this time.
Many beverage cans are marked with warnings such as "Do not put below zero". This is mainly aimed at cans and plastic bottles, because the plastic bottles themselves can be deformed to a certain extent, expanding the volume and reducing the pressure.
When carbon dioxide is dissolved in cola * * * Strictly speaking, other ingredients in cola will also have an impact. Here we can only make a rough analysis * * * Put it in a freezing room below zero, and it will not freeze quickly, because its freezing point has been lowered by dissolved carbon dioxide. * * * What's more, other ingredients in cola, such as sugar, will also lower the freezing point of liquid. ***
Therefore, in a certain temperature range below zero, cola is a liquid, and its volume will continue to expand. This will cause the pressure in the fuel tank to increase. * * * Pressure increase will further reduce the freezing point, but this effect is not obvious. * * * Then the following three situations may occur:
1, if the pressure exceeds the endurance limit of the tank, the coke will explode in the refrigerator. One of the links mentioned above mentioned that I opened the refrigerator and found frozen coke all around.
2. If the tank is strong enough to keep it cool, coke will start to freeze eventually. As the volume increases during freezing, it will crush the jar as shown above.
3. If the can is opened in the liquid state before the cola is frozen, firstly, part of the cola will be sprayed out of the can under great pressure; Secondly, when the pressure drops suddenly, the dissolved carbon dioxide will be released quickly. Liquid and gas are mixed and quickly sprayed from the tank mouth. This process can be violent, and that's how the accident happened.
