Liquid carbon dioxide is carbon dioxide gas that is highly compressed and cooled to a liquid form. Carbon dioxide exists as a liquid below the critical temperature of 31C and above the triple point with a temperature of -56.6 C and 4.18 bar.
Features
- A colorless and odorless gas that can cause the nose to sting in high concentrations
- Toxic in high concentrations, an asphyxiant (does not support life)
- Slightly corrosive in the presence of moisture
- Heavier than air, carbon dioxide will collect in ducts, drains and low-lying areas
- Highly soluble in water at moderate pressures
