Solution

Dry Ice

  • Dry ice is simply carbon dioxide that has been cooled and condensed.
  • When it reaches ambient temperature and pressure, it bypasses the melting process and expands directly into carbon dioxide gas.
  • Dry ice is made by compressing and cooling gaseous CO2 under high pressure, resulting in liquid CO2.
  • Dry ice is frequently used as a substitute for refrigeration for groceries and medical supplies due to its exceptionally low temperature of-78°C.

Uses of Dry Ice

  • Dry ice is used to keep the sensitive asphalt at the proper temperature during transportation from the manufacturing factory to the job site.
  • During breakdowns, use dry ice to keep the contents of the refrigerator cool.
  • Dry ice is the most efficient and cost-effective way of keeping perishables cooled or frozen.
