Liquid carbon dioxide (LCO2) is the liquid form of the chemical compound carbon dioxide (CO2). Carbon dioxide is a colorless, odorless gas that is found in the Earth’s atmosphere, and it is also produced by various natural and human activities.
At standard temperature and pressure, carbon dioxide is a gas, but when it is pressurized and cooled to below -78.5 degrees Celsius (-109.3 degrees Fahrenheit), it becomes a liquid. Liquid carbon dioxide is often transported and stored in pressurized tanks, which are designed to maintain its liquid state at high pressure.
Liquid carbon dioxide has various uses in industry, including as a coolant and as a solvent. It is also used in the production of certain types of food and beverages, such as carbonated drinks and dry ice.
