Dry ice is the solid form of carbon dioxide (CO 2), a molecule consisting of a single carbon atom bonded to two oxygen atoms. Dry ice is colorless, odorless, and non-flammable, and can lower the pH of a solution when dissolved in water, forming carbonic acid (H 2 CO 3). [1]

Dry ice starts off life as carbon dioxide gas (CO2). From a gas, the CO2 needs to be converted into a liquid before it can become solid dry ice. In order to get the CO2 gas into a liquid, it is pressurized and refrigerated.

Nov 28, 2023 · Dry ice is frozen carbon dioxide that's used in everything from transporting goods to removing skin imperfections. Learn more about dry ice and how to use this versatile compound effectively and safely.

Oct 21, 2024 · Dry ice is the solid form of carbon dioxide (CO2). It is called "dry ice" because it does not melt into a liquid when it warms up; instead, it sublimates directly from a solid to a gas. This process happens at a temperature of about -78.5°C (-109.3°F).

Unlike regular ice, which is frozen water (H₂O), dry ice is frozen carbon dioxide. One of its most notable properties is that it sublimates, meaning it changes directly from a solid to a gas without passing through a liquid phase. This characteristic is what gives dry ice its “dry” nature.

Mar 17, 2025 · You can make dry ice using carbon dioxide. However, carbon dioxide vapor can be harmful if you breathe too much in, so it’s best to do this somewhere with plenty of fresh air—like outdoors or in an open garage.

Jul 25, 2024 · Dry ice – what is it? Dry ice is carbon dioxide in its solid state. Its temperature is approximately -78,5°C (-109 F). CO 2 in this form has a very brittle structure. It crumbles under slight stress.

Dry ice is the solid form of carbon dioxide (CO₂), a gas that occurs naturally in Earth’s atmosphere. Unlike regular ice, which is made from frozen water (H₂O), dry ice does not melt into a liquid as it warms. Instead, it sublimates—changing directly from a solid to a gas.

Mar 22, 2025 · Dry ice, carbon dioxide in its solid form, a dense, snowlike substance that sublimes (passes directly into the vapour without melting) at −78.5 °C (−109.3 °F), used as a refrigerant, especially during shipping of perishable products such as meats or ice cream.

Jun 16, 2010 · To make dry ice, carbon dioxide gas is first cooled and pressurized to turn it into a liquid, according to Continental Carbonic Products, Inc, a dry ice manufacturer. The liquid is then...
