Dry
Ice
Dry Ice, sometimes referred to as cardice or 'card ice', is the solid form of carbon dioxide. It has a lower temperature than water ice and does not leave any residue (other than incidental frost from moisture in the atmosphere). Unlike normal ice, dry ice changes from solid to gas when it absorbs heat. Dry Ice with the temperature of -78.40C, absorbs 573 KJ of heat per Kg compared to 335 KJ per kg for water ice.
Uses
- Used primarily as a cooling agent
- Used in cold storage for preserving frozen foods, ice cream, etc.
- Used in Dry Ice blasting where mechanical cooling is unviable.
