Question

Why is it dangerous to store dry ice in an air-tight containers?

Answer 1

• Solid form of carbon dioxide (CO₂) is known as dry ice.
• It is a substance that can undergo sublimation.
• The conversion of a solid phase substance directly into its gaseous form without passing through the intermediate liquid phase is known as sublimation.
• If it is stored in an air-tight container, it will undergo sublimation and the gaseous carbon dioxide formed creates greater pressure inside the container.
• As a result, it may explode.
• So dry ice should be kept in containers that allow the gas to flow.
