What is the coldest thing in the world are people afraid of touching it

According to the information, liquid nitrogen is considered a cold substance. Let us tell you that there is plenty of nitrogen in our atmosphere. At the same time, about one-eighth of the earth is made up of nitrogen gas. It is a colorless and tasteless gas.

Let us tell you that the symbol of nitrogen in chemistry is N2. When the temperature of nitrogen goes below -195.8 degrees Celsius, then it converts into liquid form.

When there is no such place on our earth where the temperature is so low, nitrogen is always found in solid form. That is why it is converted into liquid artificially.

Dry ice is a solid form of carbon dioxide. Its special feature is that it is very cold. Let us tell you that the temperature of normal homemade ice is minus 2-3 degrees Celsius, but the surface temperature of dry ice is up to minus 80 degrees. However, it is not wet like normal ice. It is forbidden to touch it.

According to information, liquid nitrogen is much colder than dry ice. Usually its temperature is between -346°F and -320.44°F, which is very difficult for a person to bear. In such a situation, it becomes more dangerous than dry ice.
