Dec 27, 2023 · Dry ice is a compound. Carbon dioxide (CO2) in solid form, one carbon atom joined with two oxygen atoms (1:2). These compounds may not be separated except by chemical means. Dry ice is a pure substance (compound) that does not melt. It bypasses the liquid state and forms directly from solid to gas (sublimation), and contrariwise, from gas to ...
Dry ice colloquially means the solid form of carbon dioxide. It is commonly used for temporary refrigeration as CO 2 does not have a liquid state at normal atmospheric pressure and sublimes directly from the solid state to the gas state. It is used primarily as a cooling agent, but is also used in fog machines at theatres for dramatic effects.

The journey of dry ice begins with carbon dioxide gas, which is collected as a byproduct from various industrial processes like ammonia production and fermentation. This gas is then pressurized and cooled until it becomes a liquid. When the pressure is suddenly released, the liquid CO₂ expands and cools rapidly, forming solid CO₂, or dry ice.

ERG 2024, Guide 120 (Dry ice) · Vapors may cause dizziness or asphyxiation without warning, especially when in closed or confined areas. · Vapors from liquefied gas are initially heavier than air and spread along ground. · Contact with gas, liquefied gas or cryogenic liquids may cause burns, severe injury and/or frostbite.

How is dry ice formed?
Dry ice is basically solid carbon dioxide that changes directly from a solid to a gaseous phase through the process of sublimation. Carbon dioxide in its gaseous state is a chemical compound that is odor-free, colorless and tasteless. Under pressure and at low temperatures, carbon dioxide becomes an opaque white solid.
