Frozen gas
- Unlike regular ice, which is made of water, dry ice is a frozen gas that turns directly from a solid to a gas when it sublimates. Also known as cardice, carbonic ice, or CO2 ice, it serves as an ideal solution for transporting perishable items, providing efficient refrigeration and cooling in lab or medical environments.

Dry ice constantly sublimates into carbon dioxide in gas form. If you store dry ice in a sealed container, the gas released will cause pressure to build up and may cause the container to explode. Do not store dry ice in a freezer.
Nov 28, 2023 · But what is dry ice? Dry ice is frozen carbon dioxide. A block of dry ice has a surface temperature of -109.3 degrees Fahrenheit (-78.5 degrees C). Dry ice also has the very nice feature of sublimation — as it breaks down, it turns directly into carbon dioxide gas rather than a liquid.
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]
2 days ago · When it comes to cooling agents, dry ice stands out as a remarkable substance with unique properties and diverse applications. Unlike regular ice, dry ice doesn’t melt into a liquid but instead undergoes a process called sublimation, turning directly from a solid to a gas.
Apr 18, 2024 · Understanding what dry ice is and how it changes phase as it warms up is crucial for ensuring safe applications. Knowing it has frigid temperatures and turns directly into a gas can inform proper handling and storage solutions. On that note, here are six crucial tips to safely handle, store, and dispose of dry ice. 1.
Jun 16, 2010 · Unlike the ice cubes in a cold drink, dry ice doesn't melt to become liquid at all. Instead, at room temperature, it changes directly from a solid to a gas a process called...

Within a certain pressure and temperature range, solid carbon dioxide (dry ice) does not melt. Instead it sublimates or passes directly to the gas phase. If a small amount of a pH indicator known as bromothymol blue is added to tap water, a blue-green colour results.
