For keeping goods cold during shipment what is an advantage of dry ice (frozen carbon dioxide) pver water ice?

Dry ice has the advantage of maintaining a much lower temperature than water ice, typically around -78.5°C (-109.3°F), which helps keep goods colder for a longer period. Additionally, dry ice sublimates into carbon dioxide gas, avoiding the mess and potential contamination associated with melting water. This makes dry ice particularly suitable for shipping temperature-sensitive items that require a consistent cold environment without the risk of water damage.
