Wet Dry Ice

The solid form of carbon dioxide is called “dry ice” because it does not melt, as ordinary ice does, but rather goes directly from a solid to a gas—it sublimes. The liquid form of dry ice is not stable at “ordinary” pressures and temperatures (atmospheric conditions). If dry ice is allowed to sublime in a closed system, however, the pressure will increase to a point where the liquid form of carbon dioxide can be seen.
