Dry Ice: The Basics
Dry ice is solid carbon dioxide (CO₂) that sublimates (transitions directly from solid to gas) at -78.5°C (-109.3°F). It's produced by compressing and cooling gaseous CO₂ until it liquefies, then reducing the pressure to create solid CO₂ "snow" which is compressed into blocks or pellets.
Unlike regular ice, dry ice:
- Is approximately 3-4 times colder than water ice
- Leaves no liquid residue (hence "dry" ice)
- Creates gaseous CO₂ as it warms
- Requires special handling due to its extreme cold temperature
