A gray cylinder contains which gas?

Explanation:
Color coding of medical gas cylinders is a safety cue that helps identify contents quickly. Gray is the color assigned to carbon dioxide in many standard codes, so a gray cylinder typically contains carbon dioxide. This distinguishes it from other gases like oxygen (usually green or white) and nitrous oxide (often blue). Always read the cylinder’s label and inspect the valve markings as color standards can vary by country or facility.
