Q. What is Dry ice?
Answer: Solid carbon dioxide
Notes: Dry ice is the solid form of carbon dioxide. 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. It is used primarily as a cooling agent.
The most common use of dry ice is to preserve food, using non-cyclic refrigeration. It is frequently used to package items that must remain cold or frozen, such as ice cream or biological samples, without the use of mechanical cooling.
