This is probably really dumb but I wanted to know how dry ice makes that smoke. Is it water vapor? Or something else and why does it burn our skin when we come into contact with it.
In: Chemistry
Dry ice is a really cold and solid form of carbon dioxide. Thus any vapor coming from it is carbon dioxide gas. It makes the gas because it’s heating up to a temperature where carbon dioxide is a gas; the process of turning from a solid to a gas is called sublimation. It burns the skin because it is too cold for our skin to handle similar to the ice cube and salt “trick”.
