Which statement describes the CO2 discharge?

• A. The discharge forms a fine white Snow/Powder
• B. The discharge forms a visible liquid jet
• C. The discharge forms a dense colored smoke
• D. The discharge forms a warm mist

Answer: (A)

CO2 discharge appears as a fine white cloud or fog, often described as a snow-like plume. This happens because the CO2 rapidly expands and cools as it exits the cylinder and mixes with humid air, condensing moisture in the air into a visible white mist. The gas itself is colorless, and you won’t see a liquid jet, colored smoke, or a warm mist from CO2—those descriptions don’t match how CO2 behaves when released.
