Dry ice will not stay frozen in a standard freezer. Because dry ice's temperature is much lower (-109.3°F or -78.5°C), it requires much colder conditions to remain solid. In a regular freezer, dry ice will sublimate, turning directly from a solid to a gas, usually within 24 hours, depending on the block's size. For longer storage, specialized freezers are required that can maintain temperatures well below standard home freezer capabilities.
FAQs & Answers
- Why does dry ice not stay frozen in regular freezers? Dry ice sublimates at -78.5°C (-109.3°F), which is much colder than the temperature maintained by standard freezers, causing it to turn directly from solid to gas.
- How long does dry ice last in a standard freezer? Typically, dry ice will sublimate within 24 hours in a regular freezer, though exact duration depends on the size of the dry ice block.
- What kind of freezer is needed to store dry ice long term? Specialized freezers capable of reaching temperatures far below standard home freezers are required to keep dry ice solid for extended periods.
