Solid carbon dioxide is often called dry ice because at normal atmospheric pressure it never forms a liquid state. Instead of changing from a solid to a liquid and then to a gas, it jumps right from solid to gas. This is called sublimation. Dry ice is very cold, around 109 degrees below zero on the Fahrenheit scale. That’s cold enough to freeze flesh and cause frostbite which it why we always wear gloves when handling this stuff.
