Have you ever seen dry ice?
Those of you who have seen it may have seen it in science classes at school, or when ice cream is packaged in ice cream shops.
Otherwise, when you order food that is sensitive to temperature, you'll see that it came with Aispaq.
This dry ice can not be made in a typical family, but it must be made using a professional machine.
To briefly explain the process of making this gas, first of all, we compress and cool CO.
This process is then repeated to remove moisture, creating liquid CO.
If you inflate it, make a crystal, compress it again, then dry ice is created.
The dry ice makes it sublimate in the atmosphere at temperatures between - 78 degrees Celsius and 79 degrees Celsius, and reduces the temperature by taking heat from nearby.
In this case, sublimation refers to the transformation from solid to gas, which means that dry ice is literally converted into gas rather than liquid.
If you translate dry ice literally, it is called " dried ice, " which is the name given because no green water was created.
As a result, this dry ice is not wet, and as compared to its size, it is highly vaporized, so it is used for cooling purposes.
But it's a very dangerous idea to touch this dry ice with your bare hands.
And it is often said that touching these dry ice with bare hands can cause burns, which is one of the popular mistakes.

When you touch cold dry ice, the reason why you are known to be affected is because when you touch dry ice, the damage looks like it was burned. We don't see much of the damage caused by frostbite in our daily lives, and the damage caused by the burn seems to have been caused by this misunderstanding.
(Baskin Robbins)
When wrapping ice cream in Baskin Robbins, an ice cream specialty store, the phrase " Dry Ice Cream is a risk of burn, so don't touch it. "
Maybe these little phrases have given people the wrong perception.
So I asked why Baskin Robbins 31 described it as a burn rather than a frostbite.
I received a reply saying that I used the usual expression because people generally think they'll get burnt if they touch dry ice.
I don't think it makes much of a difference since it is a phrase that shouldn't be touched.
However, if you take a closer look at frostbite, there are freezing damage and non-stability damage to the cold damage.
Examples of freezing damage are frostbite
Often, damage caused by touching dry ice is freezing and resembles burn damage.
If you don't live in a cold area, you don't usually get frostbite.
Otherwise, it can be found when you touch dry ice with your bare hands.
If you see frostbite damage, it is important to warm the affected area first.
Let's go somewhere warm if you are cold environment, removed from the body is wet, and you have to help you.
The principle of frostbite therapy is to relax blood vessels to make blood circulate more freely, and to release freezing between cells.
One easy way to do this is to immerse the frostbite area in warm water at 38 to 42 ℃ for 30-60 minutes.
Water temperature is important, but it does not dissolve well under 38 ℃.
If you have an ice cream bottle, immerse it in water at 38 ℃.
Depending on the extent of the frostbite, blisters may develop, but they should never pop and should not irritate the skin's surroundings.
The best way to do this is to go to the hospital and have a precise diagnosis.
The frostbite can not occur in this country, but it could be from dry ice.
Dry ice is very interesting, but it can cause smoke if you put it in the water, and it has a lot to play with.
For your information, dry ice should not be stored in a sealed place, but as it is sublimated, it increases the pressure and could explode if opened later.
