Why Is Nitrous Oxide Stored as a Liquid

The nitrous oxide is supplied in cylinders containing between 450 and 18,000 L of gas. Nitrous oxide has a critical temperature above the room temperature, so it is stored as a liquid in pressurised cylinders, with nitrous oxide vapour present in the space above the liquid.
