The shelf life of dry ice depends mainly on how the dry ice is stored and the size of the brick. Dry ice is frozen carbon dioxide, the same gas that we exhale and that plants use for photosynthesis. It is never a liquid, it goes from a -109.3Â°F solid state directly into the gas stage. Because of these properties, dry ice enjoys most of its popularity at Halloween for making a fabulous witch's brew.
Dry ice sublimes at â78.5 Â°C (â109.3 Â°F) at Earth atmospheric pressures.
