Explanation:
Since carbon dioxide is a gas, it is easy to store and distribute. If squeezed into a steel canister, the gas streams out as you open the nozzle. Carbon dioxide is denser than oxygen. So when you spray the carbon dioxide on fire, it sinks under the oxygen, separating the fire from oxygen.
