Have you ever wondered “what is dry ice,” or “what is dry ice used for?” Well this article will tell you all about dry ice, how it works and what we use it for. So what is dry ice? Well dry ice is frozen carbon dioxide. Carbon dioxide is a gas that comes out of mammals when we breath out. A block of dry ice has a surface temperature of -109.3 degrees Fahrenheit. Also when dry ice breaks down, rather than turning into a liquid, it turns into the gas form of carbon dioxide. This is called sublimation. Touching dry ice with your skin is very dangerous and can cause burns and frostbite. This is because dry ice is so cold that when you touch it, the heat from your hand is absorbed by the dry ice.

This is why we use special gloves and gear to protect ourselves from the coldness of the dry ice. Although dry ice is dangerous, is is very useful because of it’s super cold temperature and sublimation. Dry ice is primarily used as a cooling agent but has many other helpful uses. One way that people use dry ice is, when they have to ship something frozen to another state, you can pack it in dry ice and it will be frozen all the way until it reaches it’s destination. Dry ice is used in cooking and is used in fog machine’s at theatre’s or dramatic events. Dry ice is an amazing and cool source of matter that is dangerous but very useful.
