Answer 1

Answer:

Dry ice is made by liquefying carbon dioxide and injecting it into a holding tank, where it's frozen at a temperature of -109° F and compressed into solid ice. Depending on whether it's created in a pelletizer or a block press, dry ice can then be made into pellets or large blocks.

Answer 2

Dry ice is the solid form of carbon dioxide. It is used primarily as a cooling agent, but is also used in fog machines at theatres for dramatic effects. Its advantages include lower temperature than that of water ice and not leaving any residue.
