[{"from": "human", "value": "Provide a description of this molecule. [Ar]"}, {"from": "gpt", "value": "The molecule appears as a colorless odorless noncombustible gas. Heavier than air and can asphyxiate by displacement of air. Exposure of the container to prolonged heat or fire can cause it to rupture violently and rocket. If liquefied, contact of the very cold liquid with water may cause violent boiling. If the water is hot, there is the possibility that a liquid \"superheat\" explosion may occur. Contacts with water in a closed container may cause dangerous pressure to build."}]
