What happens to liquid gas if spilled onto seawater?
Direct Answer
Option A: Rapid boiling and phase change into large gas vapor clouds
When cryogenic liquid spills onto seawater, the significant temperature differential causes instantaneous boiling. This phase change results in rapid expansion, creating large, dense vapor clouds. These clouds can be flammable or toxic, posing severe risks to the vessel and crew, necessitating immediate activation of emergency shutdown and fire-fighting protocols.
