What is dry ice?
  • Dry Ice is the common name for solid carbon dioxide (CO2).
  • It gets this name because it does not melt into a liquid when heated; instead, it changes directly into a gas (This process is known as sublimation).
  • It is used primarily as a cooling agent.
  • Its advantages include lower temperatures than that of water ice and not leaving any residue.
  • It is extremely cold and sublimates into carbon dioxide gas. So, it is useful for a wide variety of projects.
