Like I know it is made from carbon dioxide but what actually makes it so special compared to normal ice? And why is it so dangerous if it is ice?
In: Chemistry
There’s nothing really special about it. We call it dry ice because it doesn’t have a liquid state (at normal atmospheric pressure), and it doesn’t add water to whatever you’re trying to keep cool (because it isn’t water).
It’s dangerous because it’s so cold, -80°C. Normal ice just needs to be below 0°C. That will damage your skin much faster than normal ice would. It will also fill a room with carbon dioxide as it sublimates, which will kill you with carbon dioxide poisoning. In a sealed container, it will also expand as it sublimates, resulting in a build up of pressure before it explodes
