Dry ice is solid carbon dioxide(CO2). It got this name bcz it does not form liquid when heated it directly turns to gas.

Dry ice is made from carbon dioxide gas. The carbon dioxide gas is pressurized and cooled to form liquid CO2. The liquid carbon dioxide is injected into either a block press or pelletizer.
